title: Microprolactinoma with visual field defect: An unsuspected etiology.
abstract: Microprolactinomas present usually with menstrual disturbance and galactorrhoea. The presence of visual field defects is not expected in these patients as the tumor does not involve structures outside the sella. Visual field defects in a case of microprolactinoma confuse the clinician and warrant extensive search for an alternate etiology. We present a young lady with microprolactinoma and visual field defects. Etiological work-up revealed a diagnosis of idiopathic intracranial hypertension (IIH) associated with microprolactinoma. Treatment with Acetazolamide and Cabergoline completely resolved the clinical symptoms and visual defects. The unusual occurrence of IIH in a case of microprolactinoma as the cause of visual field defect is highlighted in our case report.
