MRI Highlights the Hypervascularity of Breast Keloids.

Keloids are benign fibroproliferative lesions resulting from abnormal wound healing, forming at sites of cutaneous injury or surgical incisions, not infrequently occurring following breast surgery. Five patients with keloid scars on their breasts, who underwent subsequent breast MRIs following breast surgery are described. Details on breast imaging studies, clinical course, pathology findings and therapeutic interventions were abstracted from the electronic medical records. Enhancement on MRI was qualitatively, not quantitively, determined on peak phase sequences. Regression of enhancement corresponding to the clinical attenuation of a hypertrophic scar was observed in one case three years postoperatively. This study demonstrates that breast keloid surgical scars are associated with exuberant neovascularisation.
