A rare case of cholesterol granuloma in the thyroid without an abnormality of lipid metabolism

High-riding jugular bulb (HRJB), although rare, may pose a challenge as it may be mistaken for other non-alarming condition, such as middle ear effusion. Patients with HRJB classically present with pulsatile tinnitus. We report a unique case of a 26-year-old patient with underlying beta thalassaemia who presented with a 2-month history of intermittent epistaxis and rhinorrhoea. Otoscopic examinations revealed a pulsatile bluish mass behind the right tympanic membrane and a dull left tympanic membrane. Imaging performed revealed a finding of dual retrotympanic pathology, which consisted of a right dehiscent HRJB and left cholesterol granuloma. We highlight a rare case of dual retrotympanic mass as well as its management.

Pulmonary Changes

Electron microscopy and energy dispersive x-ray microanalysis (EDXA) are found to be very useful tools for identification of etiologic agents in pneumoconiosis or interstitial pulmonary disorders. Pulmonary interstitial fibrosis and granulomatosis are frequently associated with occupational and environmental pollution. Numerous reports of pneumoconiosis in various occupations such as coal and gold miners are presented in the literature. However, there is no known documented case of pulmonary changes in workers in the sandpaper industry. This study reports a rare case of pulmonary granulomatosis containing deposits from abrasives of sandpaper diagnosed by using EDXA.

New Zealand White Rabbits

This cytochemical study was designed to investigate early metabolic changes in the aortic wall that might lead to or accompany development of atherosclerotic plaques in rabbits. The hypothesis that the primary cellular alteration leading to plaque formation might be due to changes in either carbohydrate or lipid metabolism led to histochemical studies that showed elevation of G-6-Pase in atherosclerotic plaques of rabbit aorta. This observation initiated the present investigation to determine how early in plaque formation and in which cells this change could be observed.Male New Zealand white rabbits of approximately 2000 kg consumed normal diets or diets containing 0.25 or 1.0 gm of cholesterol per day for 10, 50 and 90 days. Aortas were injected jin situ with glutaraldehyde fixative and dissected out. The plaques were identified, isolated, minced and fixed for not more than 10 minutes. Incubation and postfixation proceeded as described by Leskes and co-workers.
