Abstract
Neurocysticercosis is the most common parasitic infection involving the central nervous system and is a major health problem in endemic regions. Bone changes in cysticercosis are rare with paucity of reported cases in both humans and animals. The reported changes are usually erosions, infarctions and necrosis, defects/lytic changes, and heterotopic bone formation. In this report, we present computed tomographic temporal bone changes characterized by thickening with increased density of both the inner and outer tables, a cystic lesion interposed between the thickened calvarium and a defect in the outer table of the right squamous temporal bone. Lesions were also seen in the brain parenchyma, subarachnoid space, and muscles with subcutaneous nodules. Radiologists in endemic areas should add this feature to their gamut of localized thickened cranial vault. This rare and important finding will help us understand the devastating multisystem effects of parasites.
