OBJECTIVE There have been few reports of lingual dermoid cysts with a congenital discharging fistula. We report such a case, which mimicked lipoma on computed tomography, and we discuss relevant clinical and radiological features. METHOD We present a case report and a review of the English language literature concerning lingual dermoid cysts either mimicking lipoma or with a congenital discha...

Computed tomography (CT) was performed on 25 patients with Wilson disease (hepatolenticular degeneration). The diagnosis was confirmed biochemically. CT was normal in seven patients, five of whom presented clinically with the hepatic form of the disease. In 10 patients, CT abnormalities were graded as mild: there were atrophic changes around the basal ganglia and in the cortex and cerebellum. I...

A 51-year-old Caucasian female presented for evaluation of a superior posterior mediastinal mass. The lesion was incidentally found after the patient was involved in a motor vehicle collision. During her trauma evaluation, a computed tomography scan of the chest showed a left paraspinal lesion measuring 2.4 cm by 2 cm (Figure 1). The Hounsfield units were consistent with fluid versus low densit...

V.A. Kumar T.M. Hofstede L.E. Ginsberg SUMMARY: Palatal tumors are often treated with palatectomy or maxillectomy. The resulting surgical defect produces an oroantral communication. An obturator is a removable prosthesis used to close the palatal or maxillectomy defect. Fifteen patients who had undergone palatectomy or maxillectomy for carcinoma and subsequent obturator prosthesis placement wer...

Palatal tumors are often treated with palatectomy or maxillectomy. The resulting surgical defect produces an oroantral communication. An obturator is a removable prosthesis used to close the palatal or maxillectomy defect. Fifteen patients who had undergone palatectomy or maxillectomy for carcinoma and subsequent obturator prosthesis placement were retrospectively studied. Obturators were chara...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2014-205597 DESCRIPTION Case report A 30-year-old woman presented with severe lower, colicky abdominal pain and difficulty in passing flatus. Clinical examination revealed suprapubic tenderness. An abdominal CTwas performed which revealed a soft-tissue mass in the pe...

INTRODUCTION Muscle X-ray attenuation (MXA) in Hounsfield units (HU) is decreased in dystrophy, aging, and immobilization. We hypothesized a decrease also during bed rest (BR). METHODS Twenty-five healthy men performed BR for 90 days, 8 of whom performed flywheel exercise 2-3 times per week. Muscle cross-sectional area (CSA) and MXA were assessed by computed tomography. RESULTS In the contr...

Background The predominant cause of coronary artery calcification is atherosclerosis. Although fast x-ray computed tomography (CT) has been demonstrated to be a sensitive technique to detect coronary calcification, the increasing prevalence of calcification with age has been associated with a low specificity for identifying obstructive atherosclerosis. We hypothesized that the specificity of th...

The effects of partial volume averaging on computed tomographic images of temporal bone structures were evaluated. The models chosen for study included a cadaver stapes, two metallic prosthetic stapes, and a formalin-fixed temporal bone. The studies measured the changes in apparent dimension and Hounsfield units with incremental filling of voxels with metallic densities, changes in the angle of...

BACKGROUND Tibia shaft fractures are among the most common fractures. However, the incidence of tibia fractures does not increase in the elderly. Osteoporotic bone resorption is possibly compensated for by periosteal apposition, which improves the mechanical properties of the bone. The purpose of this study was to identify a correlation between geometric indices of transverse bone scans and rad...
