Malignant Small Bowel Neoplasms

Magnetic resonance imaging of small bowel neoplasms

Magnetic resonance (MR) imaging is rapidly increasing clinical acceptance to evaluate the small bowel and can be the initial imaging method to investigate small bowel diseases. MR examinations may provide the first opportunity to detect and characterize tumours of the small bowel. Intra- and extraluminal MR findings, combined with contrast enhancement and functional information, help to make an...

Primary malignant schwannoma of the small bowel.

Primary malignant schwannoma of the small intestine is an extremely rare disease. We report a primary malignant intestinal schwannoma of the small bowel in a 66-year-old woman, who was admitted to the hospital because of fatigue and anaemia. On clinical examination there was a solid mass at the abdomen. Ultrasound scanning showed an abdominal tumour. Computed tomography showed a mass in the are...

Malignant melanoma involving the small bowel.

Small bowel is the commonest site of gastrointestinal metastases from cutaneous malignant melanoma. Five patients with malignant melanoma involving the small bowel are reported. One patient was operated on for suspected acute appendicitis, two patients for gastrointestinal bleeding and two patients for small bowel obstruction. Two patients remain well 4 and 5 years after surgery.

MR enteroclysis in the diagnosis of small-bowel neoplasms.

PURPOSE To evaluate the diagnostic accuracy and interobserver variance of magnetic resonance (MR) enteroclysis in the diagnosis of small-bowel neoplasms, with small-bowel endoscopy, surgery, histopathologic analysis, and follow-up serving as standards of reference, and to identify MR enteroclysis characteristics capable of enabling discrimination between benign and malignant small-bowel neoplas...
