Résumé

A 23-year-old Indian man presented with shortness of breath and new-onset confusion along with a rash on his chest on Postoperative Day 2, following internal fixation of his femur fracture. Although computed tomography pulmonary angiography was negative for filling defects in the pulmonary vasculature, it showed mosaic attenuation changes with some interlobular septal thickening. Magnetic resonance imaging of the brain showed patchy signal abnormalities, predominantly in the grey-white matter junction region with extensive susceptibility artefacts, consistent with petechial haemorrhages. The laboratory work-up showed thrombocytopenia and anaemia. A diagnosis of fat embolism syndrome was established, based on the clinical presentation combined with laboratory and imaging findings. The clinical and imaging features of fat embolism syndrome are discussed.

Résumé

A 28-year-old Chinese man presented with acute bleeding per rectum. Computed tomography showed a posterior outpouching arising from the distal ileum. The outpouching had hyperaemic walls, but no active contrast extravasation was detected. Technetium-99m pertechnetate scintigraphy showed focal areas of abnormal uptake in the right side of the pelvis, superior and posterior to the urinary bladder. These areas of uptake appeared simultaneously with the gastric uptake and demonstrated gradual increase in intensity on subsequent images. The diagnosis of Meckel's diverticulum was confirmed on surgery and the lesion was resected. The clinical and imaging features of Meckel's diverticulum are discussed.

Résumé

Spontaneous spinal epidural haematoma is a rarely encountered cause of back pain. It often leads to cauda equina syndrome, necessitating emergency spinal surgery. We report the case of a 19-year-old Chinese man who presented with pain in the lower back, which started after he had carried some heavy boxes. He denied a history of fall or trauma. Magnetic resonance (MR) imaging showed a hyperintense biconvex-shaped lesion in the posterior epidural space on both T1- and T2-weighted sequences, diagnostic of a spinal epidural haematoma. The patient, who was admitted and managed conservatively, had gradual resolution of his pain. No neurological deficit was detected on discharge or on follow-up. Repeat MR imaging showed total resolution of the lumbar spinal epidural haematoma. The clinical characteristics, MR imaging features, diagnosis and management of spontaneous spinal epidural haematoma are discussed.
