Clinics in diagnostic imaging (166). Nonketotic hyperglycaemic chorea-hemiballismus.

ABSTRACT: A 68-year-old woman with poorly controlled diabetes mellitus presented to the emergency department with choreoathetoid movements affecting the upper and lower left limbs. Computed tomography of the brain did not show any intracranial abnormalities. However, subsequent magnetic resonance (MR) imaging of the brain revealed an increased T1 signal in the right basal ganglia, raising the suspicion of nonketotic hyperglycaemic chorea-hemiballismus. Management consisted of adjusting her insulin dose to achieve good glycaemic control. The patient subsequently recovered and was discharged after eight days. There are many causes of basal ganglia T1 hyperintensity, including hyperglycaemia in patients with poorly controlled diabetes mellitus. This case emphasises the importance of MR imaging in the early diagnosis of hyperglycaemia as a cause of chorea-hemiballismus, to enable early treatment and a better clinical outcome.

Corticosteroid induced hyperosmolar hyperglycaemic state and hemiballismus.

Project description:We present an 89-year-old man with new onset of left-sided hemiballismus affecting his face, arm and leg. He was found to have hyperglycaemia with a glucose level of 20.2 mmol/l and had started prednisolone 3 months earlier for polymyalgia rheumatica. A T 2-weighted magnetic resonance scan of the brain showed a hypointense lesion of the right lentiform nucleus. At follow-up, his symptoms had improved with treatment for diabetes mellitus. To our knowledge, this is the first patient to develop hemiballismus after starting corticosteroids.

Project description:A 16-year-old Chinese male patient presented with constipation lasting five days, colicky abdominal pain, lethargy, weakness and body aches. He was able to pass flatus. Abdominal radiography showed a distended stomach causing inferior displacement of the transverse colon. Computed tomography revealed a dilated oesophagus, stomach and duodenum up to its third portion, with a short aortomesenteric distance and narrow angle. There was also consolidation in the lungs bilaterally. Based on the constellation of clinical and imaging findings, a diagnosis of superior mesenteric artery syndrome complicated by aspiration pneumonia was made. The patient was subsequently started on intravenous hydration, nasogastric tube aspiration and antibiotics. Following stabilisation of his acute condition, a nasojejunal feeding tube was inserted and a feeding plan was implemented to promote weight gain. The clinical presentation, differentials, diagnosis and treatment of superior mesenteric artery syndrome are discussed.

Project description:Hydrocoele of the canal of Nuck is a rare condition in adult women caused by a failure of complete obliteration of the canal of Nuck. It may be likened to a patent processus vaginalis in men. In most cases, the diagnosis is made during surgery as it is often mistaken for an inguinal hernia. We report a case where the diagnosis of this condition was made preoperatively on imaging. The salient anatomy, clinical features, radiological images and surgical management are discussed and the medical literature reviewed.

Project description:A 30-year-old woman presented with a six-month history of left posterior heel pain. Physical examination revealed a tender, inflamed and indurated posterior heel with a visible bony prominence of the posterosuperior aspect of the calcaneus. Lateral ankle radiography showed a prominent left posterosuperior calcaneal tuberosity and thickening of the distal Achilles tendon outline. Magnetic resonance imaging demonstrated high-signal inflammatory fluid in the retrocalcaneal bursa, increased signal intensity and thickening of the Achilles tendon, and prominence of the posterior calcaneus tuberosity with reactive marrow oedema. The findings are consistent with Haglund's deformity. The patient underwent hind foot surgery after failing a six-month course of conservative therapy. There was no further recurrence of symptoms after surgery. The clinical and radiological features of Haglund's deformity are described, including a short discussion of other causes of hind foot pain.

Project description:A 20-year-old National Serviceman presented with left knee pain and swelling after training for his physical fitness test. Lateral knee radiography and magnetic resonance (MR) imaging showed patellar tendon-lateral femoral condyle friction syndrome (PT-LFCFS), on a background of patella alta and patellar malalignment. The patient was treated non-operatively with a course of physiotherapy and given advice on rest and activity modification. PT-LFCFS is a less well-recognised but important cause of anterior knee pain and represents an entity in a spectrum of disorders related to patellofemoral instability. We herein discuss the MR imaging findings specific to and associated with this condition, as well as briefly describing treatment options. In addition, we showcase a range of commonly encountered abnormalities that affect the infrapatellar fat pad and briefly discuss their specific MR imaging findings.

Clinics in diagnostic imaging (199). Pyometra.

Project description:A 92-year-old woman presented to the emergency department with urinary symptoms, fever and suprapubic tenderness. Her inflammatory markers were raised. Urine and blood cultures were negative. Computed tomography performed to look for a source of sepsis showed distension of the uterine cavity with high-attenuation fluid, an air-fluid level and gas locules along the uterine wall. The causes, clinical presentation and imaging features of pyometra are discussed.

Clinics in diagnostic imaging (194). SVC aneurysm.

Project description:A 68-year-old woman presented with weight loss of 7 kg over two years. Clinical examination revealed no specific abnormality and the patient was otherwise asymptomatic. Chest radiography performed to screen for malignancy revealed a soft tissue opacity projected over the mediastinum. Computed tomography of the thorax showed an enhancing anterior mediastinal mass with heterogeneous enhancement and contrast pooling in the arterial phase, followed by homogeneous enhancement in the venous phase, consistent with an aneurysm arising from the superior vena cava. This case highlights superior vena cava aneurysms as extremely rare causes of anterior mediastinal masses. Other causes of anterior mediastinal masses were also discussed.

Clinics in diagnostic imaging (205). Baxter's neuropathy.

Project description:A 48-year-old woman presented with chronic right heel pain and paraesthesia over the foot. Magnetic resonance imaging of the right foot demonstrated isolated atrophy of the abductor digiti minimi. A diagnosis of Baxter's neuropathy was made and the patient was managed successfully via surgical release. We describe the clinical and radiological features of Baxter's neuropathy and, with brief examples, outline other causes of chronic heel pain.

Clinics in diagnostic imaging (195). Plantar fibromatosis.

Project description:A 46-year-old man presented with a six-month history of lumps in the sole of his left foot. Physical examination revealed two nodules, one tender and one firm, at the plantar left foot with no overlying skin changes. Although the initial radiographs were normal, magnetic resonance imaging of the left foot demonstrated two nodules along the medial band of the plantar fascia, characteristic of plantar fibromas. The patient opted for surgical excision. There was no further recurrence of symptoms after surgery. We describe the clinical and radiological features of plantar fibromatosis and briefly discuss other causes of lumps and pain in the sole of the foot.
