Duodenal Tuberculosis: Radiological Features on Barium Studies and their Clinical Correlation in 28 Cases
BACKGROUND: A retrospective analysis of 28 cases of duodenal
tuberculosis (TB) was done to evaluate radiological findings and their
value in the diagnosis of the disease. subjects AND METHODS: Upper
gastrointestinal and small bowel series of 28 patients with duodenal
tuberculosis were analysed for radiological findings. The diagnosis of
duodenal TB was confirmed by surgery and biopsy in 18, on the basis of
radiological findings and response to treatment in 9, and on the basis
of findings on upper gastrointestinal scopy and biopsy in 1 patient.
RESULTS: The study included 28 patients (14 males, 14 females). The
mean age was 32.1 (range 5-65). Twenty-three (82.2%) patients presented
with obstructive symptoms while five manifested with dyspeptic
symptoms. Of the latter, 4 had ulcerations in the third and fourth
parts of the duodenum. In the remaining patient, the mucosa of the
duodenum could not be clearly visualised. Two patients had extrinsic
impression at the D2-D3 and D3-D4 segments. In 23 patients with
obstructive symptoms, 18 demonstrated luminal narrowing of varying
degrees and 5 had a sharp band-like cut-off at the third part of the
duodenum. Of the 18 patients with luminal narrowing, 13 had extrinsic
compression, 12 had proximal dilatation and 14 had ulcerations mainly
in the second and third parts of the duodenum. Biliary involvement was
seen in 3 patients without any signs or symptoms directly referable to
the biliary involvement. CONCLUSION: Though duodenal TB lacks specific
radiological features, barium studies help to localise and define the
area of narrowing and ulcerations and help to confirm the presence of
lymph nodes causing compression of the duodenum
