Acute blue finger syndrome: a rare benign cause of acute digit discolouration

Acute blue finger syndrome is a rare benign condition that mimics digital ischaemia. We discuss the case of a 32-year-old woman who presented with a 6hour history of blue discolouration of the middle finger of the right hand, associated with pain and swelling. There was no history of trauma and this was the first time that the patient had experienced these symptoms. Examination found blue discolouration of the digit primarily on the volar aspect with associated swelling. All investigations, including blood tests, X-rays and Doppler scanning, were normal. The symptoms resolved spontaneously within 48 hours. There were no recurrent episodes or long-term sequelae. Patients presenting with an acutely blue finger need rapid assessment to exclude digit ischaemia. Knowledge of this rare benign condition may prevent unnecessary distress, invasive investigations and potentially harmful treatment of a healthy patient.

Rare case with plethora of upper urinary tract anomalies associated with pelviureteric junction obstruction: a surgical challenge managed with robot assistance

The genitourinary system for reasons unknown is more likely to have birth defects than any other system. The anomaly of collecting system draining the kidney represent mystifying subset of congenital anomalies. Pelviureteric junction obstruction (PUJO) is most common. Chronic obstruction can lead to stasis, urinary infection and stone formation in PUJO. Extrarenal calyces, which is characterised by presence of calyces and renal pelvis outside the renal parenchyma is one of the rare anomalies seen among the collecting system right gonadal vein drains into inferior vena cava. Its altered drainage into right renal vein is rarely seen and reported. Glut of these multiple anomalies in a single case is an extremely rare event. We hereby discuss a case of 40-year-old male patient with combination of all these anomalies and discuss the embryology, presentation and management.

Primary Ewing sarcoma of the kidney

Primary Ewing sarcoma (ES) or primitive neuroectodermal tumour (PNET) is a rare tumour in adults and primary renal involvement is extremely rare. Patients with renal ES or PNET respond to and would benefit from conventional ES treatment according to ES study protocols. Here, we report a case of a young woman, presenting with right flank pain and haematuria. After ultrasound and CT evaluation, a right middle pole renal mass was detected. The patient underwent radical right nephrectomy, and a grade 4 ES with peritoneal involvement was documented. Subsequently, the patient underwent adjuvant chemotherapy for 5 months. Follow-up 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT scan demonstrated bilateral cervical, hilar, mediastinal and retroperitoneal FDG-avid adenopathies associated with mild right-sided pleural effusion with no metabolic activity, signifying the role of PET/CT scan in tumour restaging.

Ileal conduit volvulus: rare complication of urinary diversion

Ileal conduit volvulus is a rare complication of urinary diversion. It has been suggested that various factors including prolonged length of the ileal segment, lack of fixation of the conduit to the peritoneum and failure to close the incised mesentery predispose patients to this complication. We present the case of a 76-year-old man who presented to hospital with severe abdominal pain and oliguria secondary to a volvulus of his ileal conduit. Investigations revealed early acute kidney injury as a result of urinary obstruction which was evident on abdominal CT. The patient subsequently underwent operative repair of the volvulus. Symptoms resolved following the procedure, kidney function improved and the patient was discharged without complication.

Peroneal artery entrapment syndrome (PRAES): a rare cause of ischaemic toes

A 75-year-old man presenting with intermittent discolouration of his left toes was referred to vascular surgery with suspicion of embolic vascular disease. A contrast-enhanced MR angiogram was performed which revealed bilateral dominant peroneal arteries (PRAs). There was evidence of short atherosclerotic stenosis directly at the point where the left PRA passes through the tibiofibular interosseous membrane which we postulate to be the source of the emboli. We present what is believed to be the first reported case of PRA entrapment complicated by distal toe emboli.

Behavioural changes as the first manifestation of a silent frontal lobe stroke

A 67-year-old man was admitted to our hospital after his relatives found him to have severe personality and behavioural changes. His behaviour was inappropriate and uninhibited. The patient reported no symptoms and he showed poor insight into his own behaviour. Neuroimaging showed an orbitofrontal lesion, due to an infarction of the anterior cerebral artery. The patient was diagnosed with frontal lobe syndrome.

Double axillary vein variation diagnosed with ultrasound guidance during infraclavicular nerve block intervention

The use of ultrasound guidance increases the safety of peripheral block interventions by allowing anaesthesiologists to simultaneously see the position of block needle, the targeted nerves and surrounding vessels. In this report, we represented three patients diagnosed with double axillary vein variation with ultrasound guidance during infraclavicular nerve block intervention. The patients were scheduled for different types of upper limb surgeries. All patients received infraclavicular nerve block for anaesthetic management. A double axillary vein variation was diagnosed with ultrasound during block interventions. Hydro-location technique was used in all cases and the procedures were completed uneventfully. In the current literature, there is limited number of reports concerning double axillary vein variation. Detailed knowledge of the axillary anatomy is important to avoid complications such as intravascular injection during peripheral nerve block interventions. The use of ultrasound guidance and hydro-location technique should be considered for nerve blocks, especially in the axillary area.

Pseudomonas meningoencephalitis masquerading as a stroke in a patient on tocilizumab

A previously high-functioning woman presents with clinical and CT features of a subacute ischaemic stroke. Her medical history is relevant for refractory giant cell arteritis on long-term high-dose prednisolone and recent commencement of tocilizumab (interleukin-6 monoclonal antibody). The potential for stroke mimic is considered and a magnetic resonance brain scan is requested. She rapidly deteriorates within 24 hours of admission and unexpectantly dies. An autopsy reveals that she has bilateral pulmonary emboli with lower limb deep vein thrombosis and Pseudomonas meningoencephalitis with frank pus on the brain. We discuss the potential risks of immunosuppression and the role of imaging in the diagnosis of stroke.

Intestinal obstruction caused by small bowel adenocarcinoma misdiagnosed as psychogenic disorder

We describe a case of intestinal obstruction caused by a small bowel adenocarcinoma misdiagnosed as psychogenic disorder. A woman in her 40s was admitted to Nagoya City University Hospital with fatigue, anorexia, nausea and vomiting. CT, oesophagogastroduodenoscopy and colonoscopy revealed no signs of organic abnormality in her gastrointestinal tract. As the patient had previously been diagnosed with and treated for depression, her symptoms were suspected to be due to psychogenic disorder. Therefore, she was diagnosed with severe depression and was administered antidepressant agents. Despite intense psychiatric treatment, her symptoms worsened and she was later diagnosed with ileus due to adenocarcinoma in the jejunum. After drainage by insertion of a transnasal decompression tube, a partial jejunum resection was performed. After the resection, the patient's symptoms including fatigue and depression resolved without the use of antidepressant agents.

Simultaneous presentation of thyroid storm and diabetic ketoacidosis in a previously healthy 21-year-old man

A 21-year-old young man with no history of diabetes or thyroid disease presented to the emergency department with simultaneous thyroid storm and diabetic ketoacidosis. Notable findings on admission were a ventricular rate of 235 beats/min, tachypnoea, tremors, polydipsia and a lack of fever. Due to the unusual constellation of symptoms, diagnosis was only possible after initial laboratory results came back. While the lack of fever is unusual in thyroid storm, diabetic ketoacidosis has previously been reported to suppress fever, and this case supports the occurrence of this phenomenon. This case was highly unusual because the patient had not previously been diagnosed with either type 1 diabetes or Graves' disease.

Rectal bleeding caused by a syphilitic inflammatory mass

A 47-year-old man presented with fatigue, decrease appetite, abdominal pain and rectal bleeding. His colonoscopy revealed a single, firm, raised, centrally ulcerated mass at the anorectal junction. During this same admission, he was diagnosed with HIV and syphilis, found to have multiple hepatic lesions and positive cerebrospinal fluidvenereal disease research laboratory test (VDRL). Biopsies from both the hepatic lesions and rectal ulcer showed spirochaetes by immunostaining. The initial presentation was felt to be secondary to a rectal inflammatory mass caused by syphilis.

Hypocalcaemia and hyponatraemia masquerading the diagnosis of Gitelman syndrome

Gitelman syndrome is the most common renal tubulopathy, recently exhibiting a dramatic rise of incidence in Asia.

A 50-year-old woman presented with vomiting, fatigue and quadriparesis. Physical examination revealed a positive Trousseau sign , hypotonia and areflexia.

Suspecting hypocalcaemia, she was given intravenous 10% calcium gluconate (10 mL administered slowly over 10 min) but her manifestations persisted. An exhaustive laboratory work up revealed the diagnosis of Gitelman syndrome.

The peculiarity of this case however, is entailed in its coexistence with hypocalcaemia and hyponatraemia. In addition, the age of primary presentation being 50 years further culminates its atypicality.

Multiple electrolyte imbalances were corrected by oral and intravenous supplementation and a high sodium-potassium diet was advocated. Administration of spironolactone imposed a pitfall in the management of our patient due to exacerbation of pre-existing hyponatraemia.

On follow-up, her electrolyte profile was stable and corresponding symptoms were alleviated.

Aortitis and pachymeningitis: an unusual combination in granulomatosis with polyangiitis (myeloperoxidase-associated vasculitis)

Aortitis and pachymeningitis are uncommon manifestations of the antineutrophil cytoplasmic antibody-associated vasculitides, a group of systemic autoimmune diseases mainly affecting small vessels. We present a case of a 71-year-old woman with a remote history of idiopathic chronic granulomatous pachymeningitis complicated with aortic thickening due to autoimmune aortitis.

Hepatitis in patients with syphilis: an overlooked association

We present the case of a patient who sought treatment for fever and a maculopapular rash involving the trunk, limbs, palms and soles. The patient also presented with hepatomegaly and elevated levels of liver enzymes (with a higher increase of alkaline phosphatase). With the proposal of early syphilitic hepatitis, during the stage of secondary syphilis, a venereal disease research laboratory and Treponema pallidum haemagglutination tests were requested, which confirmed the diagnosis. All altered parameters improved with antibiotic treatment for secondary syphilis. Syphilitic hepatitis is an often overlooked presentation of syphilis and should be considered as a differential diagnosis in patients with elevated levels of liver enzymes and risk factors for syphilis.

Actinomycosis of the omentum with invasion of the abdominal wall, small bowel and transverse colon mimicking malignancy

We report the case of a 59-year-old Russian man who presented with a painless, slow-growing, epigastric mass. CT revealed a large heterogeneous mass within the omentum infiltrating into adjacent tissues. During diagnostic laparoscopy, the omental mass was noted to be firm, raising the suspicion of malignancy. Surgical en-bloc resection of the mass, including the posterior rectus sheath, transverse colon and small bowel, was performed with primary anastomoses at laparotomy. Histological examination was inconsistent with malignancy and revealed the mass to be actinomycosis, confirmed by microscopy and gram staining. Surgical resection was followed by an 8-week course of penicillin and doxycycline antibiotic therapy. This treatment resulted in full clinical and radiological recovery with no complications. Although the clinical and radiological findings, in this case, were highly suspicious of malignancy, abdominal actinomycosis should be considered a differential diagnosis in patients with infiltrative abdominal masses and mild constitutional symptoms.

Largest giant juvenile fibroadenoma of the breast

Juvenile giant fibroadenoma is a rare benign tumour of the breast accounting for 0.5% of all fibroadenomas. The presentation can be very dramatic and may result in breast deformity and may mimic a rare malignant tumour. It is indeed a great challenge to provide the best treatment for these patients in terms of clinical and psychological care. Meticulous surgical planning is required to ensure a fine balance between adequate resection and the best cosmetic outcome for a developing breast. Every effort should be made to preserve the developing breast irrespective of the size of the tumour as it is in this case. We report the world's largest juvenile fibroadenoma of the breast in a 16-year-old girl who presented to our hospital with a 28x25 cm mass on her left breast in which breast conservation was done. A detailed literature search and management of these lesions are discussed.

Very rare case of synchronous volvulus of the sigmoid colon and caecum causing large-bowel obstruction

Large-bowel obstruction caused by volvulus is potentially life threatening if not managed promptly. Sigmoid colon is the most common site of volvulus followed by caecum. Synchronous double colonic volvulus is an exceedingly rare entity, with only five cases published previously. We present the case of a 77-year-old man with a synchronous sigmoid and caecal volvulus. He underwent total colectomy with ileostomy formation with a view to reverse the ileostomy at a later date.
