Contrast-enhanced computed tomography scan of the abdomen showed multifocal inflammatory wall thickening and thick-walled abscess pockets with the beaded appearance of subcutaneous small abscesses in the precoccygeal and perianal area (fig. 2, fig. 3).
Follow-up colonoscopy after recovery of pancytopenia demonstrated disappearance of the multiple active aphthous ulcerations; diffuse fibrotic scar formation (suggesting accelerated mucosal healing) was noted instead.

Follow-up colonoscopy was performed 3 months later and demonstrated diffuse fibrotic scar instead of multiple ulcerations (fig. 4).
