Summary
A woman experienced sudden hemiplegia due to an acute hematoma. Advanced magnetic resonance imaging (MRI) and computed tomography (CT) confirmed the diagnosis, leading to successful surgical intervention.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Acute hemiplegia necessitates rapid diagnosis and intervention.
- Magnetic resonance imaging (MRI) and computed tomography (CT) are crucial for evaluating emergent neurological conditions.
Observation:
- A patient presented with acute onset hemiplegia.
- MRI revealed a hyperintense mass on diffusion-weighted imaging (DWI) with specific T2*/T2/PD signal characteristics.
- T1-weighted imaging demonstrated an inhomogeneous lesion with central acute clot and peripheral plasma.
Findings:
- Computed tomography (CT) confirmed a hyperdense hematoma, excluding other mass lesions.
- The imaging findings were consistent with an acute intracranial hemorrhage.
Implications:
- Prompt diagnosis via advanced neuroimaging is critical for emergent conditions like hemiplegia.
- Surgical evacuation of the hematoma via decompressive craniotomy can be a life-saving intervention.
