Unenhanced MRI shows the exact position and morphology of the lesion in sagittal view, with the characteristic capsule of the mass suggesting a working diagnosis of lipoma (Figure 1).
Lipoma arises from the subcutaneous tissues of proximal phalanx of the right first digit.

The fatty, lobulated mass was found to be localized in the subcutaneous tissue and was attached close to the proximal and middle phalanx of the digit without interfering with the fascicles of the tendon (Figure 2).
Removal of the tumor including the extensions into the tendon sheath.

The neoplasm was removed completely including the extensions into the tendon sheath avoiding damage to the neurovascular bundles (Figure 3).
