Table 2 Computed tomography findings of intraperitoneal tuberculous abscess in 8 patients

Case	Location, size (cm), shape and margin of the abscess	Location of the enlarged lymph nodeand its size (cm)	Number of rim-enhanced lymph nodes
1	(1) Subphrenic space, 3 × 3.5 × 7.2, irregular shape, the margin was poorly defined (2) Perihepatic space, 5 × 8.9 × 12.2, irregular shape, the margin was poorly defined with adhesion to the gastric wall and gallbladder (3) Lower abdominal cavity, 4.5 × 5.8 × 7.1, irregular shape, the margin was well defined	Pericardial region and para-aortic region; the largest lymph node was < 1	Small number
2	Middle-lower abdominal cavity, 6.5 × 6.8 × 7.6, irregular shape, the margin was well defined encasing the mesenteric vessels	Mesenteric root and beside the abscess; the largest lymph node was < 1	Small number
3	Peripancreatic region, 3.7 × 4.1 × 4.5, regular shape, the regional margin of the abscess was poorly defined	Peripancreatic and portacaval space; the largest lymph node was 2.7 × 1.8	Multiple
4	(1) Lower abdominal cavity, 5.1 × 6.0 × 6.2, irregular shape, the regional margin was poorly defined (2) Lower abdominal cavity, 2.1 × 3.8 × 5.5, irregular shape, the margin was well defined	Lymph nodes clustered in the mesenteric root; the largest lymph node was < 1	Small number
5	Peripancreatic region, 3.1 × 3.8 × 5.1, regular shape, the regional margin was poorly defined	Peripancreatic region and the hepatogastric ligament; the largest lymph node was 2.5 × 1.7	Multiple
6	Beside the jejunum, 2.5 × 4.2 × 5.0, regular shape, the regional margin was poorly defined encasing the mesenteric vessels	Peripancreatic region and the hepatogastric ligament; the largest lymph node was 2.3 × 1.5	Multiple
7	Beside the ileum, 3.2 × 4.0 × 5.1, regular shape; the regional margin was poorly defined encasing the mesenteric vessels	Para-aortic region and mesentery; the largest lymph node was 0.8 × 1.3	Small number
