“…A recent retrospective series showed that 34% of all SFTs occur in the abdominopelvic region, indicating that the abdominopelvic cavity is the primary site of SFT [3]. Among these, SFTs arising from the mesentery are rare, and only six cases to our knowledge have been reported within the mesorectum [4][5][6][7][8][9]. SFTs are mesenchymal neoplasms.…”

“…This tumor has been observed in various locations, and recently, several cases of abdominopelvic SFTs have been reported [3]. Mesorectal SFTs are rare, and to our knowledge, only six cases have been reported [4][5][6][7][8][9]. Compared to SFTs in the pleura, SFTs within the pelvic cavity are often larger and are associated with a higher likelihood of malignancy at the time of detection [7,10].…”

Solitary fibrous tumors (SFTs) are rare tumors that predominantly occur in the mesorectum. Few case reports have been published on mesorectal tumors, and this is the seventh case report. A 49-year-old female patient presented with a hypervascularized mesorectal tumor discovered incidentally during a routine medical examination. Using preoperative three-dimensional computed tomography (3D-CT), we identified vessels originating from the superior rectal and lateral sacral arteries, which are important sources of nutrients, and performed the procedure safely and without bleeding. Considering the lack of preoperative diagnosis and rectal blood flow, high anterior resection was performed. The histopathological diagnosis confirmed SFT, and the patient is currently doing well with no recurrence. Although SFT of the mesorectum occurs infrequently, it should be included in the differential diagnosis. In addition, the usefulness of preoperative 3D-CT, including the arterial phase, has been emphasized in such cases. This is the seventh reported case of a rare SFT in the mesorectum. Currently, there is no literature highlighting the usefulness of 3D-CT for SFTs of the mesorectum. However, it is a valuable preparatory tool for preoperative evaluation.
