Abstract:
Primary malignant lymphoma is a non-Hodgkin lymphoma which occurs in the brain in the absence of systemic involvement. A 63-year-old woman presented to emergency service, complaining of sudden onset vomiting and dizziness. She was unconscious when she was admitted to the hospital. She had no complain, until a week ago when she experienced a headache nonresponding to analgesic. Preliminary diagnosis was cerebrovascular hemorrhage or intracranial mass. Magnetic resonance imaging and PET/CT yielded a mass filling all ventricles. Histopathology of the mass matched with malignant lymphoma located in the ventricles.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
