AI Article Synopsis
- Atypical spindle cell/pleomorphic lipomatous tumor is generally classified as a benign tumor, but can be confusing to diagnose due to varying MRI findings.
- In this case, imaging suggested a potential atypical lipomatous tumor or liposarcoma, leading to a wide resection after a needle biopsy showed benign to low-grade malignancy.
- The final diagnosis was confirmed through detailed histopathology techniques, highlighting the importance of tissue analysis over imaging alone for accurate diagnosis.
Article Abstract
Atypical spindle cell/pleomorphic lipomatous tumor is categorized as a benign lipomatous tumor, but various MRI findings pose accurate diagnostic challenges. In our case, both MRI and PET/CT scans indicated the possibility of atypical lipomatous tumor/well-differentiated liposarcoma or dedifferentiated liposarcoma. Needle biopsy suggested benign to low-grade malignancy; hence, we opted for the wide resection. The final diagnosis of atypical spindle cell/pleomorphic lipomatous tumor was confirmed through histopathology analysis, including immunohistochemistry and fluorescence in situ hybridization. Since achieving an accurate diagnosis solely through imaging can be challenging, histopathology remains essential.
