PATHOLOGY: pararectal IMT. Axial and coronal reformations of contrast-enhanced CT on portal (a, b) and 8 min after injection delayed acquisitions (c, d). Pararectal solid and well-defined mass with moderated peripheral enhancement adjacent to the rectum and left seminal vesicle was detected. e Macroscopic view of the tumour after surgical resection. f Histological sample obtained after biopsy. Mesenchymal neoplasm composed of polygonal cells with clear cytoplasm and round normochromatic nuclei with abundant vessels and occasional scattered inflammatory cells was observed. Mixed within the neoplasm cells, there was a chronic inflammatory infiltrate of lymphoid cells. There were no foci of necrosis or mitotic figures
