Intraabdominal abscess: current concepts in radiologic evaluation.

Forty patients with suspected abdominal abscess had computed tomography (CT) and plain film examinations; 15 also had ultrasound study. CT was found to be the most consistently accurate examination, both for the detection of abscess and evaluation of its extent. Ultrasound was positive in a high percentage of cases in which it was used. Although plain films correctly suggested the presence of an abscess in over half the proven cases, confirmatory evidence from CT or ultrasound was often required to persuade clinicians of the presence of an abscess and to provide detailed information regarding its extent and configuration.

Ultrasonic imaging of the amniotic and chorionic cavities.

This paper presents two cases illustrating separate chorionic and amniotic sacs at 5 to 6 weeks of estimated gestational age. With higher resolution scanning units and higher-frequency transducers, the delineation of the amniotic membrane can be seen before it fuses with the chorionic membrane; this should not be interpretated as an abnormality.

Imperforate anus and colon calcification in association with the prune belly syndrome.

Two patients with the prune belly syndrome demonstrated colon calcifications and anorectal malformations. Bladder outlet obstruction was present in both cases. Calcifications were also found in the renal collecting system and bladder of one patient. No fistula was demonstrated between the genitourinary tract and bowel in either infant at autopsy. The calcification in the colon and urinary tract is probably secondary to stasis.

Posterior urethral valves as a cause of neonatal uriniferous perirenal pseudocyst (urinoma).

Two neonates with uriniferous perirenal pseudocysts (urinomas) secondary to posterior urethral valves are presented. Early diagnosis was achieved and both patients survived. The characteristic roentgenographic appearance of the pseudocyst is described. An investigation for lower urinary tract obstruction should always be undertaken when pseudocyst or ascites is seen in the neonate. Prompt diagnosis and treatment is essential to avoid irreversible renal damage, electrolyte or fluid imbalance, or respiratory compromise.

Principles and applications of a dynamically focused phased array real time ultrasound system.

The physical principles and clinical applications of a high-resolution, dynamically focused phased-array real time ultrasound are described. Advantages of the real time technique include rapid survey capability, efficient selection of an appropriate tomographic plane, identification of pulsating structures, and dynamic studies. The capabilities of a high resolution phased array with extended dynamic focusing to a range of 15-20 cm are demonstrated in vascular, abdominal, and obstetric imaging. Appropriate clinical examples showing normal and pathological anatomy are presented. Comparisons with conventional B scans are illustrated.

The use of CT scanning in resolving "pseudo" lesions of the liver.

The authors have presented three cases in which bowel, fat, or fluid interposed between the liver and abdominal wall resulted in an equivocal or abnormal radionuclide scan of the liver. Ultrasound was useful in suggesting the etiology in only one instance. In all three cases, however, computerized tomography clearly demonstrated the etiology of the defect or "pseudo" lesion seen on the radionuclide scan.

Toxopachyosteose diaphysaire tibio-peroniere (Weismann-Netter-Stuhl syndrome): two case reports.

Two patients with the Weismann-Netter-Stuhl syndrome are presented, one with classic and widespread findings, the other with minimal changes. Subsequent to its initial description in the French literature seven cases have been reported in English. The syndrome is characterized by anterior bowing of the tibia and fibula with posterior cortical thickening and trabecular irregularity in the region of bowing. Other long bones may be similarly affected. Scoliosis and pelvic findings are frequent. Short stature is usually present. The syndrome appears to be a generalized diaphyseal dysplasia.

Antenatal detection of fetal structural defects with ultrasound.

A case report of a cystic hygroma detected in utero by ultrasound at 16 weeks' gestation is presented. The potential for early second trimester detection of both CNS and non-CNS structural defects by diagnostic ultrasound is discussed "High risk" groups for fetal structural defects can be identified for screening purposes.
