Von Hippel-Lindau (VHL) syndrome is a rare neoplastic disorder characterized by central nervous system (CNS) and visceral tumors. We here present 68Ga-labelled [1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid]-1-Nal3-Octreotide positron emission tomography computed tomography findings in a 52 year old female with VHL syndrome, demonstrating both CNS and visceral tumors.

Myositis ossificans is defined as formation of bone at the site of injured muscle. It is one of the rare complications of supracondylar fracture of humerus in children. Myositis mass usually develops on the anterior aspect in the brachialis muscle and produces restriction of range of motion, but complete ankylosis is rare. To the best of our knowledge, this is the first case to be reported in the literature as a consequence of myositis ossificans traumatica. In this case, a six-year-old child presented to the casualty department with pain in the right elbow after a fall on outstretched hand during play. After surgical excision through the anterior approach, the child had no symptoms referable to the elbow and a residual flexion deformity of 15 degrees with further painless flexion up to 100 degrees at last follow-up of one year after surgery.

BACKGROUND: This study was undertaken to identify the prevalence of pulmonary embolism (PE) in the emergency department (ED) of an urban teaching hospital and also to test a Bayesian model in estimating the number of CT pulmonary angiography (CTA) expected to be performed in an emergency department. METHODS: The data for this study was obtained through a retrospective review of electronic medical records for all ED patients suspected of PE who underwent chest CTA or ventilation perfusion scanning (V/Q) between 2009 and 2010. The data is presented as means and standard deviation for continuous variables and percentages with 95％ confidence intervals (95％CI) for proportions. The prevalence of PE was used as pre-test probability in the Bayesian model. Post-test probability was obtained using a Fagan nomogram and likelihood ratios for CTA. RESULTS: A total of 778 patients (560 females) with mean age of 50 years (range 18–98 years) were enrolled (98.3％ underwent chest CTA and 1.7％ underwent V/Q scan). A total of 69 patients had PE, rendering an overall prevalence of 8.9％ (95％CI, 7.1％ to 11.1％) for PE. We calculated that 132 CTA's per year could be avoided in our institution, without compromising safe exclusions of PE (keeping post-test probability of PE below 2％). CONCLUSIONS: Despite differences in our patient populations and /or study designs, the prevalence of PE in our institution is about average compared to other institutions. Our proposed model for calculating redundant chest CTA is simple and can be used by institutions to identify overuse of CTA.
