Solitary rectal ulcer syndrome mimicking rectal neoplasm on MRI.
Solitary rectal ulcer syndrome (SRUS) is a rare condition that typically affects young adults and describes a spectrum of clinicopathological abnormalities. The diagnosis of SRUS is usually made on the basis of a combination of presenting symptoms and endoscopic and histological appearances. Characteristic radiological appearances have been described on transrectal and endoanal ultrasound, defecating proctography and barium enema. The radiological appearance of solitary rectal ulcer on MRI has not been previously described. MRI appearance of thickened ulcerated mucosa in the anterior rectal wall are non-specific and was indistinguishable from a malignant process. However, given that solitary rectal ulcer has a pre-disposition to occur in the anterior rectal wall, the presence on MRI of thickened rectal mucosa in this location could suggest solitary rectal ulcer in the correct clinical context.
