A 50-year-old man who presented with a history of sudden onset of frontal headache and visual impairment was admitted to another medical centre and MRI revealed a non-enhancing sellar lesion with suprasellar and infrasellar extension. Thereafter, the patient's consciousness deteriorated progressively and he showed signs of herniation; he was then referred to our centre for further evaluation. CT scanning revealed infarction of the left internal carotid artery territory. Transcranial resection of the tumour followed by a large decompressive craniotomy restored the blood flow in the internal carotid artery. Histological examination revealed the tumour to be a pituitary adenoma that contained formed blood elements. The patient's neurological status did not improve and he died on the ninth postoperative day despite vigorous treatment for controlling intracranial pressure. This case study documents a rare presentation of pituitary apoplexy that caused signs of raised intracranial pressure due to mechanical obstruction of an internal carotid artery with resulting infarction.eninfo:eu-repo/semantics/closedAccessCerebral infarctionDecompressive craniectomyPituitary apoplexyVascular occlusionCerebral infarctionHemorrhageManagementSurgeryNeurosciences & neurologyCarotid artery diseasesCarotid artery, internalHumansMagnetic resonance imagingMaleMiddle agedPituitary apoplexyTomography, x-ray computedArticle0002542681000252-s2.0-3964911560248048315418262423Clinical neurologyNeurosciencesHypophysis Apoplexy; Pituitary Neoplasms; Cranial Nerve DiseasesDesmopressinGlucocorticoidAdultArticleArtificial ventilationBlood flowBrain damageBrain edemaBrain herniaBrain infarctionBrain surgeryCancer surgeryCase reportComaComputer assisted tomographyConsciousness levelCraniotomyDiabetes insipidusHeadacheHealth centerHistopathologyHumanHuman tissueHypophysis adenomaHypophysis apoplexyInternal carotid artery occlusionIntracranial pressure monitoringMaleMedical assessmentMicroscopyNeurologic examinationNuclear magnetic resonance imagingPostoperative periodPriority journalVisual impairment
