PA is an uncommon infection of the central nervous system (CNS). Many reports were of the primary type, originating from a normal pituitary gland. In contrast, few were reported to be of the secondary type with abnormal coexisting lesions such as pituitary adenoma, craniopharyngioma, or Rathke's cleft cyst. Clinical presentations most commonly manifest as fever, altered consciousness, visual disturbances, and headaches, all of which may mimic pituitary apoplexy. Although craniopharyngiomas generally have a favorable prognosis, the formation of intratumoral abscesses can introduce additional morbidity. We present a case report of an 81-year-old Thai male who initially presented with visual disturbances for three months and later developed acute headaches with fever for two days. We aim to describe the patient's clinical presentation, laboratory and radiological investigations, and all therapeutic managements performed during his course of treatment. Thus, although this condition remains rare, a high index of suspicion and early diagnosis can lead to prompt treatment and better patient outcomes.MedicineArticleSCOPUS10.1016/j.inat.2026.1022522-s2.0-10503350645322147519
