Summary
A rare benign colonic schwannoma mimicked malignancy on MRI due to restricted diffusion and enlarged lymph nodes. Definitive diagnosis required histopathology, even after oncologic resection.
Area of Science:
- Gastroenterology
- Oncology
- Radiology
Background:
- Colonic schwannomas are rare gastrointestinal mesenchymal tumors.
- Distinguishing benign schwannomas from malignancy preoperatively can be challenging.
- This case highlights a benign colonic schwannoma mimicking malignancy radiologically.

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
