The case of a 61 years old female patient with coincidental tuberculum sellae meningeoma and pituitary adenoma is demonstrated. Because of deteriorating vision of the left eye and bitemporal hemianopia the patient was investigated. Primary arranged computertomographical investigation showed a tall intra- and suprasellar solid homogeneous tumor. The plain skull film revealed sellar enlargement; angiographically craniolateral displacement of Aa. cerebri anteriores was found. Only MRI cleared up two coexisting tumors, an intrasellar lower enhancing tumor close to another extra-/parasellar. Neuroendocrinological investigations including insulinhypoglycaemiatest and the combined pituitary anterior lobe test showed findings to be seen typically in tuberculum sellae meningeomas. Only very discrete signs for a disturbance of anterior lobe secretion could be found. Postoperatively only a discrete deterioration of clinical symptoms and neuroendocrinological findings were noticed. The diagnosis of two coincidental tumors was confirmed histologically. Two years after operation no tumor-recurrence was seen. This case is comparable with cases published until now.
