A lipoma is a benign fatty lump that commonly forms under the skin but can also occur deeper in the body.
A lipoma often feels like a soft, smooth lump under the skin that moves slightly when touched. Most are painless, though some become uncomfortable if they press on nearby tissues.
Imaging helps when the lump is deep, large, painful, growing, or not clearly behaving like a simple fatty lump.
Ultrasound, CT, or MRI help confirm fatty composition and assess whether the mass has simple or atypical features.
Many lipomas only need reassurance, while painful, enlarging, or unusual lesions may be removed or investigated further.
This entry explains the finding. The next step is having a radiologist interpret your specific scan, not a general definition.
