[Imaging features of retained surgical foreign bodies]. / Aspects radiologiques des textilomes.

PURPOSE: To study the clinical and radiological manifestations in patients with retained surgical foreign bodies. PATIENTS AND METHODS: Over the last five years, seven patients were found to have retained surgical foreign bodies after abdominal surgery. An analysis of the clinical signs, laboratory findings and imaging features was performed. RESULTS: The clinical and laboratory data were non-specific. The diagnosis of textiloma was suggested based on imaging findings and surgical history before surgical exploration. The characteristic imaging findings at ultrasound and computed tomography consisted of a fluid collection with internal wavy structures. The differential diagnosis includes pyogenic abscesses, hematomas and ruptured hydatid cysts. CONCLUSION: Ultrasonography and computed tomography are essential for the diagnosis and management of retained surgical foreign bodies after abdominal surgery.

Intraabdominal panniculitis. Report of three cases and review of the literature.

Intraabdominal panniculitis is a rare, benign idiopathic disorder of the mesentery. Patients usually present with abdominal pain and a palpable mass. The cross-sectional imaging findings are characteristic and consist of a fibrofatty central mesenteric mass lesion encapsulating the mesenteric vessels with displacement of the bowel loops, that can suggest the diagnosis. Imaging is also important to establish a definitive diagnosis by an image-guided percutaneous biopsy, assess extent of the disease for selection of appropriate therapy, exclude associated abnormalities namely malignancies, and for follow-up.
