Introduction: Pituitary apoplexy is a rare, life-threatening condition resulting from hemorrhage or infarction of the pituitary gland, most commonly in patients with pre-existing pituitary tumors. It typically presents with a sudden headache, visual disturbance, ophthalmoplegia, and altered mental status. An uncommon but serious complication is ischemic stroke in the middle cerebral artery (MCA) territory, particularly in the absence of direct internal carotid artery (ICA) compression. Case: We report a case of a 36-year-old male who presented with headache, visual impairment, and fever. Initial computed tomography (CT) brain imaging demonstrated a heterogeneous sellar lesion with peripheral calcification measuring 2.4 × 3.2 × 2.7 cm, suggestive of a pituitary mass with possible apoplexy, without evidence of acute cerebral infarction. The patient subsequently developed dysarthria, hemianopia, and reduced consciousness, prompting repeat neuroimaging. Follow-up CT revealed a large hypodense area in the right fronto-parieto-temporal region consistent with ischemic infarction. Magnetic resonance imaging confirmed an acute infarct in the right MCA territory without hemorrhagic transformation. A sellar-suprasellar mass measuring 2.3 × 2.8 × 3.8 cm was identified, consistent with a pituitary macroadenoma with intratumoral hemorrhage compressing the optic chiasm, but without direct right ICA compression. Time-of-flight mineralocorticoid receptor antagonists demonstrated attenuated flow in the right ICA (C2–C7), suggesting intracranial ICA thrombosis and reduced perfusion in the right MCA and its branches. Laboratory evaluation revealed hyperthyroidism and hypocortisolism, with no evidence of coagulopathy. The patient was treated with corticosteroid replacement and carbimazole and referred for neurosurgical management. Conclusion This case highlights a rare association between pituitary apoplexy and MCA stroke, possibly mediated by vasospasm, inflammation, or hypercoagulability. More research is needed to understand this connection and improve treatment strategies.
