Abstract

The case is reported of a 55-year-old man with diffuse malignant lymphoma type B associated with transient optic chiasm infiltration and visual disturbances but with persistent hypopituitarism, hyperprolactinaemia and diabetes insipidus. The patient was administered chemotherapy and radiotherapy. Repeated MR and CT scans showed optic chiasm infiltration, which disappeared in the course of the chemotherapy but then recurred, changed its appearance and finally disappeared again. In the meantime visual disturbances occurred and disappeared during the therapy. Hypopituitarism, diabetes insipidus and hyperprolactinaemia were diagnosed and replacement therapy was administered. Later on abdominal pain occurred, and a CT scan revealed bilateral kidney masses and enlarged retroperitoneal lymph nodes. These were diffuse malignant lymphoma with regional lymphonodulitis in histology. Finally, hydrothorax and hydroretroperitoneum were diagnosed. The patient died as a result of systemic complications of the disease. The length of survival time documented following the hypothalamochiasmatic infiltration and diagnosis of lymphoma makes the case an unusual one for patients with CNS lymphoma. Hormonal disturbances accompanying the suprasellar region infiltration are very important from the practical point of view.
