Delayed brain abscess as a complication of cerebral infarction: A rare case report and review of the literature.

INTRODUCTION

Systemic infections are a common complication of cerebral stroke, while the development of a cerebral abscess on the background of infarcted brain tissue is an extremely rare occurrence. Here, we present a new case alongside a literature review.

CASE PRESENTATION: A previously healthy 37-year-old man presented with sudden right-sided weakness and speech difficulties, progressing to complete aphasia. Initial tests showed no abnormalities, but subsequent CT scans revealed left basal ganglia infarction. Despite treatment and improvement, three months later, his condition worsened, leading to surgical intervention to excision of a cerebral abscess caused by Staphylococcus aureus. Following successful surgery and treatment, the patient showed improvement and was discharged for regular follow-up care.

DISCUSSION: The convergence of stroke and brain abscess poses serious clinical challenges, requiring prompt diagnosis and treatment to mitigate catastrophic consequences. Brain abscess, stemming from cerebral infection, may arise from various sources, including contiguous spread, hematogenous dissemination, or traumatic injury. Diagnosis is complicated by nonspecific radiological findings, which often lead to misdiagnosis. Risk factors include age, immunocompromised states, and certain medical conditions. Despite challenges, early detection and appropriate management, involving surgical drainage and antimicrobial therapy, are crucial for favorable outcomes.

CONCLUSION

Cerebral abscess following cerebral infarction is rare but should be suspected in patients with prior stroke or hemorrhage, experiencing worsening focal deficits and consciousness. Advanced age and comorbidities increase clinical suspicion.
