Summary
Hibernoma, a rare benign tumor from fetal brown fat vestiges, can appear in the interscapular region. Imaging shows specific characteristics, and complete excision is the recommended treatment for this non-malignant condition.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Hibernoma is a rare benign neoplasm originating from brown adipose tissue remnants.
- It is often mistaken for other lipomatous tumors, necessitating accurate diagnostic approaches.
Observation:
- A case of interscapular hibernoma is presented.
- Computed tomography (CT) revealed a well-circumscribed, hypodense mass with peripheral enhancement.
- Magnetic resonance imaging (MRI) demonstrated intermediate high T1 and T2 signal intensities with incomplete fat suppression.
Findings:
- Hibernoma exhibits distinct imaging features on CT and MRI.
- The tumor is benign with no malignant potential, characterized by its origin from brown fat vestiges.
Implications:
- Hibernoma should be considered in the differential diagnosis of soft-tissue tumors, particularly lipomatous ones.
- Complete surgical excision is the established and effective treatment for hibernoma.
- Accurate diagnosis prevents unnecessary aggressive treatment for this benign condition.
