Acute appendicitis: CT and US correlation in 100 patients.

Purpose: To compare the accuracy of computed tomography (CT) and ultrasonography (US) in the diagnosis of acute appendicitis.

Materials And Methods: One hundred consecutive patients were examined with US and CT, and the results, independently reported, were correlated with surgical and histopathologic findings (69 patients) and data from other laboratory and clinical follow-up (31 patients).

Results: Fifty-four patients had acute appendicitis; 46 patients did not.

Polycystic liver disease with obstructive jaundice: treatment with ultrasound-guided cyst aspiration.

A 59-year-old woman with polycystic liver (PCLD) and kidney disease (PCKD) presented with jaundice, fever, and abdominal pain. A computered tomographic (CT) scan performed immediately after an endoscopic retrograde cholangiopancreatogram (ERCP) clearly demonstrated a hepatic cyst obstructing the biliary system. The cyst was then aspirated under ultrasound guidance with complete relief of obstruction.

Acute splenic sequestration crisis in two adults with sickle cell disease: US, CT, and MR imaging findings.

Acute splenic sequestration crisis (ASSC) is a rare complication in adults with sickle cell disease that is diagnosed clinically by means of sudden splenic enlargement and a rapid fall in hematocrit. Two cases of ASSC in adults with heterozygous sickle cell disease (sickle cell-thalassemia and sickle cell-hemoglobin C disease) were studied with use of duplex Doppler ultrasound (US), computed tomography (CT), and magnetic resonance (MR) imaging. In both cases, US showed patency of the splenic vein and multiple hypoechoic lesions on the periphery of an enlarged spleen that were of low attenuation on CT scans and hyperintense on both T1- and T2-weighted MR images.

Pelvic mucocele following colostomy: CT and ultrasound findings.

Mucocele formation is a rare complication of colorectal surgery. We present a case of a mucocele following colostomy and mucosal proctectomy for fecal incontinence. The pathophysiologic and radiologic features are similar to those of mucocele of the appendix.

Imaging evaluation of children after falls from a height: review of 45 cases.

The injury pattern in the child who falls from a height is markedly different from that in the adult, so a different imaging protocol is needed. To help establish such a protocol, the authors reviewed the charts and imaging records of 45 children and infants 12 years of age and younger who had fallen one to six stories. Extremity fractures were the most common injury, occurring in 20 patients.
