Among patients with bacterial meningitis, a cerebral vasospasm typically occurs during the acute phase. We experienced a case of delayed cerebral vasospasm with infarction that was secondary to Listeria monocytogenes meningitis. An 82-year-old woman with Listeria monocytogenes meningitis, whose symptoms had been improving after the initiation of antibacterial therapy, fell into a coma on day 15 and developed generalized seizure. Magnetic resonance imaging (MRI) and MR angiography (MRA) indicated a cerebral vasospasm with multiple infarctions. The risk of vascular complications following acute bacterial meningitis requires close follow-up to identify neurological changes and a low threshold for vascular evaluation. In such cases, MRI and MRA have diagnostic utility.

Traumatic brain injury is frequently involved in cases of hypopituitarism. We report a case of panhypopituitarism due to transection of the pituitary stalk that we diagnosed 9 years after the traumatic brain injury. If a patient develops unexplained or non-specific symptoms, the physician should consider the possibility of hypopituitarism.
