Abdominal sonographic study of autosomal dominant polycystic kidney disease.
PURPOSE: The purpose of this study was to determine whether kidney size in patients who have autosomal dominant polycystic kidney disease (ADPKD) is related to renal function, hypertension, or extrarenal manifestations of the disease and to sonographically evaluate the abdominal manifestations of ADPKD. METHODS: Between 1994 and 1998, 400 individuals from 85 families with a history of ADPKD were examined. There were 213 persons with ADPKD and 187 unaffected family members; there were 182 males and 218 females, 1-82 years old (mean, 39.3 years). We obtained a complete medical history, performed a physical examination, measured the arterial blood pressure and serum creatinine levels, and performed abdominal sonography on each subject. The sonographic features that were studied were renal length and the presence and number of cysts on the kidneys, liver, and pancreas. RESULTS: There was a relationship between kidney size and age (p < 0.05), kidney size and renal function (p < 0.001), and kidney size and hypertension (p < 0.001). The overall prevalence of hepatic cysts in patients with ADPKD was 67%, and the prevalence increased with age. The presence of hepatic cysts was related to the severity of renal disease. Females had more severe polycystic liver disease, and massive polycystic liver disease (ie, hepatomegaly with innumerable cysts) was seen only in females. The prevalence of pancreatic cysts in the 187 persons in whom the pancreas was well evaluated sonographically was 5%. CONCLUSIONS: Kidney size in patients with ADPKD is related to renal function, hypertension, and extrarenal involvement and can be used to predict the outcome of the disease. Hepatic cysts are very common in patients with ADPKD and are related to age and renal function; pancreatic cysts are infrequent in these patients.

Sonographic appearance of a retained surgical sponge in the neck.
We report the sonographic appearance and clinical course of a retained surgical sponge in the neck beginning 6 months after a partial thyroidectomy. Sonograms showed a subcutaneous curvilinear hyperechoic interface with marked acoustic shadowing obscuring the left side of the neck. Three months later, a fistulous tract could be seen. Surgical exploration revealed a florid foreign tissue reaction due to a retained surgical sponge. Early diagnosis of retained sponges is important to enable expeditious removal before complications develop.

[Melanoma metastasis to the gallbladder].
Metastasis to the gallbladder is rare. Malignant melanoma is the tumor that most often metastasizes to this site. For this reason, the finding of solid lesions in the gallbladder wall in patients with advanced stage melanoma should lead to the suspicion of metastatic disease. The aim of this report is to describe and illustrate a case of surgically confirmed malignant melanoma metastasis to the gallbladder and to review the most significant ultrasound findings described in the literature for gallbladder lesions caused by melanoma.

[First radiological description of Morgagni's hydatid. Laparoscopic confirmation].
The authors explain the clinical case of a female patient suffering from secondary sterility; she was submitted, among other test, to the H.S.G. in order to study the possibility of a among other tests, to the H.S.G. in order to study the possibility of a cervical failure. The radiological findings obtained of Morgagni's Hydatis, not described previously in literature and their laparoscopic confirmation justify, we believe, its publication.
