Delayed peritoneal and retroperitoneal abscesses caused by spilled gallstones: a complication following laparoscopic cholecystectomy.

Many complications following laparoscopic cholecystectomy have been reported. We report a case of delayed peritoneal and retroperitoneal abscesses caused by spilled gallstones from a laparoscopic cholecystectomy performed 1 year earlier. This diagnosis was suggested only at sonography because the aggressive behavior of the lesions containing nonopaque gallstones suggested, by computed-tomography scan, peritoneal metastatic disease.

Sonographic detection of ingested foreign bodies in the inferior vena cava.

Ingested foreign bodies usually proceed uneventfully through the intestinal tract; complications rarely occur. The wide variety of clinical presentations they produce often make the diagnosis difficult. We report two cases of sonographic detection of foreign bodies in the inferior vena cava, namely one toothpick and one small (chicken?) bone, which probably caused a duodenocaval fistula. Both patients were initially investigated for recurrent septic episodes, weight loss, and deterioration of general condition.

Crescent-shaped necrosis: a new imaging sign suggestive of stromal tumor of the small bowel.

We report three cases of unsuspected stromal tumors of the small bowel (STSB). These cases were diagnosed preoperatively by sonography, the imaging was completed for some with barium studies, computed tomography, magnetic resonance imaging, or angiography. To our knowledge, the use of this noninvasive technique for detecting this type of tumor has not been described in the literature. Moreover, we believe that some sonographic findings such as crescentic tumoral necrosis may appear highly suggestive of STSB.
