Summary
Cerebral hydatid cysts are rare, especially in the brainstem. Surgical removal of these brain cysts can be life-saving but carries significant risks, as demonstrated in these two cases.
Area of Science:
- Neurology
- Parasitology
- Neurosurgery
Background:
- Cerebral hydatid cysts are uncommon intracranial masses, with posterior fossa and brainstem locations being exceptionally rare.
- Hydatidosis, caused by the tapeworm Echinococcus granulosus, can affect the central nervous system.
Observation:
- Two cases of brainstem hydatid cysts mimicking brainstem tumors were observed.
- CT scans revealed hypodense lesions without contrast enhancement.
- MRI confirmed the cystic nature of the lesion, showing homogeneous, hyposignal intensity with smooth limits on precontrast T2-weighted images.
Findings:
- Surgical intervention involved cyst aspiration and membrane removal.
- Postoperative outcomes were varied, with one patient succumbing to complications and the other experiencing severe deficits.
- Postoperative CT scans confirmed complete cyst resolution.
Implications:
- This case series highlights the diagnostic challenges and surgical complexities of brainstem hydatid cysts.
- Early and accurate diagnosis is crucial for appropriate management and improved patient outcomes.
- The management of intracranial hydatid cysts requires a multidisciplinary approach.
