Imaging Findings

Axial T1-weighted fat-saturated MR image (A) shows a 1.5-cm mass (arrow) with intermediate to high signal intensity in the subcutaneous fat of the right lower quadrant that extends into the right rectus abdominis muscle. Axial T2-weighted MR image (B) shows low signal intensity in the mass (arrow). Axial contrast-enhanced T1-weighted MR image (C) shows uniform enhancement of the mass (arrow).

  • Endometrioma
  • Hematoma
  • Hernia
  • Primary or secondary malignancy

Diagnosis

Endometrioma

Teaching Points

Endometrioma in a surgical scar is rare and occurs in 1% of patients who have undergone obstetric or gynecologic surgery. Patients with endometrioma in a surgical scar may present with localized cyclical pain. A fine-needle aspiration cytologic examination can be performed to confirm the diagnosis of endometrioma. If symptomatic, abdominal wall scar endometriomas often are removed surgically.
