[Pituitary tumour as a presenting symptom of a systemic lymphoma].

Pituitary non Hodgkin malignant lymphomas are rare. We report a case of large cell systemic lymphoma with pituitary and meningeal localizations in a 40-year-old patient. The clinical picture was panhypopituitarism with MRI appearance of pituitary adenoma and VII and VIII cranial nerves involvement. Diagnosis was made by identification of lymphomatous cells in CSF. The patient deceased in less than one year despite chemotherapy.
