Summary
Spindle cell hemangioendothelioma in skeletal muscle is rare. This case report details the first imaging evaluation of an intramuscular spindle cell hemangioendothelioma, showing findings similar to intramuscular hemangioma.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Spindle cell hemangioendothelioma (SCH) is a rare vascular tumor.
- Intramuscular occurrence of SCH is exceptionally uncommon.
- No prior studies have documented the imaging characteristics of intramuscular SCH.
Observation:
- A 46-year-old woman presented with a tumor in the right extensor digiti minimi muscle.
- The tumor was surgically resected en bloc.
- The patient remained disease-free for 8 years post-resection.
Findings:
- Radiologic imaging revealed findings consistent with intramuscular hemangioma.
- This represents the first reported imaging evaluation of an intramuscular spindle cell hemangioendothelioma.
- Histopathological confirmation of the diagnosis is implied.
Implications:
- This case expands the understanding of rare tumor presentations in skeletal muscle.
- Imaging findings may aid in the diagnosis of intramuscular SCH.
- Further research into the imaging features of rare intramuscular neoplasms is warranted.
