Primary small bowel tumors: a radiologic-pathologic correlation
1Section of Radiology, Department of Gastroenterology, Postgraduate Institute of Medical Education and Research, Sector 12, Chandigarh 160012, India.
Background:
Primary small bowel tumors are rare and their preoperative diagnosis is unsatisfactory. The cornerstone of diagnosis remains contrast radiography. The present study was done to evaluate the radiologic findings of primary small bowel tumors as shown on enteroclysis and to correlate these observations with surgical and histopathologic findings.
Methods:
Seventy two patients with primary small bowel tumors identified by enteroclysis were evaluated. All the patients were subjected to jejunal biopsy or surgery. The diagnosis was established by histopathologic examination in all cases.
Results:
Radiologic findings were suggestive of benign tumors in 19 patients and malignant tumors in 31 patients. Nonspecific findings in the form of diffuse involvement of the small bowel were noted in 22 patients. There was 100% radiologic-surgical correlation. Leiomyomas and lymphomas were the most common benign and malignant tumors, respectively. Tumor specificities were 89.5% for benign tumors and 41.5% for malignant tumors.
Conclusion:
Distinctive morphologic patterns as shown on enteroclysis are highly suggestive of specific tumor types in the majority of cases.
