A rare chronic fluid hematoma in the brain, mimicking a tumor, was successfully treated. This case highlights unusual intracerebral hematoma resolution, offering insights into rare neurological conditions.
Area of Science:
- Neurology
- Neurosurgery
- Pathology
Background:
- Intracerebral hematomas typically resolve, with chronic fluid collections being exceptionally rare.
- This case report focuses on an unusual instance of intracerebral fluid hematoma.
Observation:
- A 70-year-old female presented with a six-month history of memory disturbance.
- Imaging revealed a right frontal lobe lesion with cystic and solid components, mimicking a brain tumor.
- The lesion was adjacent to the lateral ventricle.
Findings:
- Surgical removal and pathological examination identified reactive changes from intracerebral hemorrhage.
- The fluid component may have resulted from dilution with cerebrospinal fluid, inhibiting coagulation.
Implications:
- This case expands the understanding of rare intracerebral hematoma presentations.
- Recognizing such entities is crucial for accurate diagnosis and appropriate neurosurgical management.
