Pituitary apoplexy is a potentially life-threatening acute or subacute clinical syndrome occurring from enlargement of the pituitary gland, and pituitary insufficiency, from hemorrhage or ischemia from an unknown pituitary lesion, most frequently being a non-functioning macroadenoma. A close, and multidisciplinary management is required. The purpose of this case report is to increase awareness to pituitary apoplexy presentation and management by reporting clinical features and neuroradiological findings observed in a 70-year-old patient with an unknown pituitary lesion. He presented with pituitary apoplexy and brain ischemia at magnetic resonance imaging (MRI) including diffusion-weighted imaging (DWI), and apparent diffusion coefficient (ADC)maps. MR angiography (MRA) showed diffuse vasospasm of anterior and posterior circulation. Both MRI and cytochemical examination of the cerebrospinal fluid ruled out subarachnoid hemorrhage. Due to concomitant diseases, and absence of visual deficit, the management was conservative by medical and substitutive therapy, without surgery. Clinical follow-up showed clearcut improvement, and this was consistent with MRI and MRA evidence of vasospasm regression, and clearcut pituitary lesion shrinkage. Pituitary lesions with hemorrhagic infarction presenting with pituitary apoplexy may be associated with vasospasm and brain ischemia at diagnosis, also in the absence of subarachnoid hemorrhage. A correct MR evaluation of patients with pituitary apoplexy should include DWI, ADC maps, and MRA. Notably, early diagnosis of pituitary apoplexy-associated vasospasm and cerebral ischemia avoids the possibility of their detection only after neurosurgery.
