Anterior abdominal wall lipoma ultrasound case study

CASE–1

Clinical History

A 45-year-old patient presented with a slowly growing, painless swelling in the epigastric region of the anterior abdominal wall. The swelling has been present for several months to years with no history of trauma, infection, or constitutional symptoms. Clinical examination revealed a soft, mobile, non-tender subcutaneous lump.

Ultrasound Findings

Ultrasound examination demonstrates a well-defined, oval, encapsulated, homogeneous echogenic soft tissue lesion within the subcutaneous plane of the anterior abdominal wall in the epigastric region. The lesion is oriented parallel to the skin surface and contains fine internal linear echogenic striations. No calcification, cystic degeneration, surrounding edema, or invasion of the underlying musculature is identified. Color Doppler demonstrates no significant internal vascularity.

Report Line

A well-defined encapsulated homogeneous echogenic lesion is seen within the subcutaneous plane of the anterior abdominal wall in the epigastric region, measuring approximately ____ × ____ × ____ mm. The lesion demonstrates fine internal linear echogenic striations with no significant internal vascularity on color Doppler. No underlying muscular invasion or surrounding inflammatory changes are noted. Ultrasound features are suggestive of a lipoma.

Impression

Features are consistent with a Anterior abdominal wall Lipoma

Report Line

A well-defined encapsulated homogeneous echogenic lesion is seen within the subcutaneous tissue of the right flank region of the anterior abdominal wall, measuring approximately ____ × ____ × ____ mm. The lesion demonstrates fine internal linear echogenic striations with no significant internal vascularity on color Doppler imaging. No extension into the underlying abdominal wall musculature is identified. Sonographic features are suggestive of a benign lipoma.

Impression

Features are consistent with a subcutaneous plane of the right flank region of the anterior abdominal wall Lipoma,

Recommendation

Clinical correlation is recommended. Surgical consultation may be considered if the lesion is symptomatic, increasing in size, cosmetically concerning, or if histopathological confirmation is required after excision. Follow-up ultrasound may be performed if interval growth or atypical features develop.

Key Learning Points

Lipoma is the most common benign soft tissue tumor of the anterior abdominal wall.
Typical ultrasound appearance is a well-defined, encapsulated, homogeneous echogenic lesion with fine linear internal striations.
The lesion usually lies within the subcutaneous fat and is oriented parallel to the skin surface.
Color Doppler typically demonstrates absent or minimal internal vascularity.
Absence of irregular margins, marked vascularity, calcification, or deep tissue invasion favors a benign lipoma.
Rapid increase in size, pain, heterogeneous echotexture, or infiltrative margins should prompt further evaluation with MRI or tissue diagnosis.
Symptomatic or enlarging lipomas are usually treated by surgical excision.
