Waldenström macroglobulinemia (WM) is a type of non-Hodgkin lymphoma in which cancer cells produce large amounts of an abnormal protein that can cause hyperviscosity syndrome (HVS). A 43-year-old woman with WM, who developed seizures, had a head computed tomography scan that showed signs of cerebral venous thrombosis (CVT). Nevertheless, the value of immunoglobulin M was lower than 50 g/L, and evaluation of serum viscosity was not performed. Moreover, there was no history of bleeding, and the eye funduscopy was normal. These findings lead to think of causes of CVT other than HVS in a patient with WM.

Cysticercosis is a parasitic infection caused by larval cysts of the tapeworm Taenia solium. It is highly prevalent in rural areas of developing countries with poor sanitary conditions. We report a rare case of extensive disseminated cysticercosis in a 98-year-old woman who was brought to the emergency department following a fall. The x-ray revealed numerous ‘rice grain’ calcifications predominantly oriented in the plane of muscle fibres. A broad review revealed pelvic, chest and inferior limb involvement. The findings were consistent with cysticercosis.
