Presentation
History of two cesarian sections, presented with a cyclic painful nodule at the cutaneous scar.
Patient Data
There is an ill-defined subcutaneous soft tissue mass abutting the anterior margin of the left rectus abdominis muscle. It elicits an iso-to slight high signal to the muscles on T1, inhomogeneous high signal on T2 with heterogeneous enhancement on postcontrast sequences. No extension to the underlying rectus abdominis muscle.
Case Discussion
The clinical history of cyclic painful nodule and its location at the site of cesarean section scar as well as the MRI features are most consistent with scar endometriosis which was confirmed by biopsy.
