18F-fluorodeoxyglucose-positron emission tomography-computed tomography (18FDG-PET-CT) and non-contrast CT. Upper row: lung lesion (red arrowheads), lower row: small intestinal lesion with wall thickening in the left lower abdominopelvic cavity (yellow arrowheads).

In addition to FDG accumulation in the lung lesion, focal accumulation (SUVmax 4.30) was found in the small intestine in the pelvic region of the left lower abdomen, where circumferential wall thickening was observed (Figure 1). Computed tomography (CT) showed wall thickening in the pelvic region of the left lower abdomen (Figure 1).
Plain abdominal X-ray imaging. (a) Plain abdominal radiography (standing position) showed no patency capsule or shape deformity. (b) Plain abdominal radiographs (lateral and decubitus positions) showing the localization of the patency capsule (PC, in the lateral and decubitus views. The PC had already dissolved into a shell only (yellow box).

No obvious PC was observed on standing plain abdominal radiography (Figure 2a). Reviewing the standing view again, we could barely recognize the shell overlapping the sacrum (Figure 2a,b).
Small bowel capsule endoscopy (SBCE) findings. SBCE revealed a neoplastic lesion with stenosis and a patency capsule shell on the oral side of the stenosis.

Furthermore, SBCE revealed the PC shell in the intestinal tract on the oral side of the stenosis (Figure 3).
Balloon-assisted enteroscopy. A neoplastic lesion with stenosis and loss of villous structure is observed in the jejunum, approximately 70 cm from the ligament of Treitz (yellow arrowhead). The patency capsule shell and small bowel capsule endoscopy passed at the time of the examination.

A neoplastic lesion with stenosis and loss of villous structure was observed in the jejunum, approximately 70 cm from the ligament of Treitz (Figure 4).
