RESUMEN

Arcanobacterium haemolyticum, found as normal flora in healthy individuals, is an unusual culprit for pharyngitis and sinusitis in young adults, rarely leading to severe infections. Here, we present a singular case involving a 19-year-old immunocompetent male who experienced complications arising from A haemolyticum sinusitis, leading to orbital and intracranial sinogenic complications. The patient developed severe cerebral vasospasm with delayed cerebral ischemia, necessitating aggressive management encompassing daily catheter-directed intra-arterial infusions, surgical source control, and maximal medical therapy. This case explores the challenging diagnostic and management aspects associated with cerebral artery vasospasm secondary to bacterial meningoencephalitis. The abrupt neurological decline in such patients presents a dilemma in recognizing the occurrence of cerebral vasospasm versus the progression of meningoencephalitis. By utilizing computed tomography brain perfusion scans, we were able to identify delayed cerebral ischemia due to cerebral vasospasm, acknowledging that this modality was not used to identify classical territorial stroke infarcts. This decision was made based on the understanding of the potential for bacterial-induced cerebral vasospasm to involve both hemispheres.
