Abstract:
Solitary fibrous tumor (SFT) is a rare spindle cell tumor originating from mesenchymal tissue, and even rarer when it occurs intracranially. This case report described a 42-year-old man who presented with headache and limb weakness for more than 10 days. Magnetic resonance imaging (MRI) showed a well-defined multicompartmental cystic space-occupying lesion in the left occipital region, with surrounding edema and a compressed left lateral ventricle, the mass growing across the cerebellar vermis, which was initially diagnosed as hemangioblastoma. Neurosurgery was utilized to successfully remove the mass, and intracranial solitary fibrous tumor (ISFT) was identified by postoperative pathological analysis. Here, this article describes the imaging manifestations and pathologic features of a case of cystic intracranial solitary fibrous tumor, aiming to improve the understanding and diagnosis of this disease in order to provide an accurate therapy plan.
Insights
A rare cystic intracranial solitary fibrous tumor (ISFT) was identified in a 42-year-old man presenting with neurological symptoms. Surgical removal and pathological analysis confirmed the ISFT diagnosis, aiding understanding of this uncommon condition.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm.
- Intracranial occurrence of SFT is exceptionally rare.
- This case highlights a cystic variant of intracranial SFT (ISFT).
Observation:
- A 42-year-old male presented with headache and limb weakness.
- MRI revealed a cystic, space-occupying lesion in the left occipital region with mass effect.
- Initial diagnosis based on imaging was hemangioblastoma.
Findings:
- Surgical resection of the lesion was performed.
- Postoperative pathological analysis confirmed the diagnosis of intracranial solitary fibrous tumor (ISFT).
- The tumor exhibited cystic characteristics.
Implications:
- This case contributes to the understanding of cystic ISFT imaging and pathology.
- Accurate diagnosis is crucial for appropriate therapeutic planning.
- Enhanced awareness can improve diagnostic accuracy for rare intracranial tumors.
