Middle cerebral artery ischaemic stroke can mimic brain tumors due to variable anatomy, leading to misdiagnosis. This case highlights a striatocapsular infarction initially mistaken for a neoplastic process.
Area of Science:
- Neurology
- Neuroimaging
- Vascular Neurology
Background:
- Ischaemic stroke in the middle cerebral artery (MCA) territory can present atypically.
- Variable MCA anatomy contributes to unusual clinical and radiographic findings.
- Misdiagnosis as neoplastic or infectious conditions is a known challenge.
Observation:
- A 69-year-old comatose woman was initially diagnosed with a brain tumor and significant edema.
- Referral for further evaluation was prompted by the unusual presentation.
- The patient presented with coma and was suspected of having a brain tumor.
Findings:
- Advanced imaging confirmed a large left-sided lenticular nuclear infarction.
- The infarction extended into adjacent brain regions, consistent with striatocapsular infarction.
- The final diagnosis was ischaemic stroke, not a neoplastic process.
Implications:
- Accurate diagnosis of MCA ischaemic stroke is crucial to avoid treatment delays.
- Awareness of atypical presentations can improve diagnostic accuracy.
- Distinguishing stroke from tumors is vital for appropriate patient management and therapeutic interventions.
