Abstract
Among pituitary tumors, prolactin (PRL)-secreting pituitary adenomas are by far the most frequent ones. The development of symptomatic hydrocephalus due to a pituitary adenoma is an exceptional event. The authors describe a 37-year-old man who had a pituitary adenoma associated with obstructive hydrocephalus that was managed by endoscopic transnasal transsphenoidal surgery. Postoperative CT and MRI scans showed resolution of the obstructive hydrocephalus and the foramen of Monro was open. Postoperatively, the patient had visual and headache improvement. Subsequently, the patient is a candidate for cranial surgery or medical therapy to complete the treatment. The present case highlights the fact that pituitary adenomas with obstructive hydrocephalus should be distinguished from other tumors especially colloid cysts.

We describe a patient who had a pituitary adenoma associated with obstructive hydrocephalus treated by endoscopic transnasal transsphenoidal surgery
The present case was unusual because the patient had a pituitary macroadenoma secreting prolactin with obstructive hydrocephalus
Summary
Sellar tumours have a large histological variability and represent approximately 10% - 15% of all intracranial neoplasms; from them pituitary adenomas represent 95% of lesions [1]. Depending on the population surveyed, their reported annual incidence varies from 1.0 to 7.6 per 100,000 populations [2] [3]. Patients with prolactinoma usually present with endocrinological symptoms and, less commonly, with visual defects due to compression of the optic chiasm [4]. The development of symptomatic hydrocephalus due to a pituitary adenoma is an excep-. (2014) Obstructive Hydrocephalus Caused by Pituitary Adenoma: A Case Report. Transnasal surgery for transsphenoidal access to the pituitary and adjacent skull base has undergone rapid evolution in recent years. The transsphenoidal approach for pituitary adenomas may be complicated by incomplete resection because of limited visualization and inability to maintain free circulation of cerebrospinal fluid [8].
