Ultrasound imaging of subepithelial rectal tumors (review)
Subepithelial rectal tumors are a group of histologically heterogeneous neoplasms located under the epithelium of the mucosa and have no specific clinical manifestations. Differential diagnosis of these tumors is an urgent problem, since the prognosis and treatment choice depend on the specific type of tumor. The aim of the work was to study the possibilities of the ultrasound method in the diagnosis of subepithelial rectal tumors and to identify signs for each type of tumor. An analysis of the literature data showed that ultrasound as an integral part of complex diagnostics using medical imaging methods (ultrasound, CT, MRI) makes it possible to identify and characterize these tumors, providing valuable information for the treatment.
