Rectum and perirectal space can be affected by a wide variety of tumours and tumour-like conditions,
which may present with similar symptoms to those of rectal adenocarcinoma,
such as hematochezia,
or change in bowel habits.
On the other hand,
tumours of the perirectal space are commonly congenital,
asymptomatic and they are malignant only in 20-35% of cases (1)
Anatomical characteristics of perirectal space are complex and magnetic resonance (MR) is the modality of choice for its assessment,
since it provides high soft tissue contrast and depicts layers of rectal wall as well as anatomic landmarks of pelvis.
It is essential to achieve the best knowledge of these features,
since multidisciplinary teams are becoming increasingly important and the radiologist should be a fundamental component of them.
