A neonate with congenital disseminated neurofibromatosis involving skin, subcutaneous tissues retropharyngeal, retroperitoneal and urinary bladder is presented. The massive presentation precluded radical surgical approach. This seems to be the first report of congenital widely disseminated neonatal neurofibromatosis in the English literature.
An antenatal detection of unilateral torsion of uterine adnexa was made by means of ultrasonography on the 32nd gestational week. This presented as an asymptomatic large "pseudo-cystic" mass, and was resected electively at the age of two weeks. A "fluid-fluid" level on ultrasonography is highly suggestive of this rare entity. This is the fourth case in the English literature to have been detected antenatally, and among the first dozen to be reported in the neonatal period.
Abnormalities of the fetal face were diagnosed prenatally by ultrasound in six cases. These included four cases of cleft lip and palate, one case of cyclopia with holoprosencephaly, and one case of fetal facial hemangioma. Of the fetuses with cleft lip and palate, one had trisomy 13, and one had Pierre Robin syndrome. Facial anomalies detected by ultrasound may suggest the presence of other accompanying malformations and may sometimes warrant chromosomal studies. Thus, careful imaging of the fetal face is an important part of ultrasound examination when evaluating the fetus at risk.

Bronchial mucoepidermoid tumours (MET) are rare in children. Only 11 cases have been reported in the literature, all of them of the low grade type. A cure is achieved by complete surgical removal of the tumour and bronchoscopy is only used for detection and biopsy. The case of a 12-year-old boy with MET in the bronchus intermedius posed a therapeutic dilemma. In this case, non-intentional removal of the tumour was achieved by bronchoscopy and the patient had no further surgery. Repeated bronchoscopies failed to show recurrence of the tumour after 2.5 years.
An ambulatory set-up is presented which comprises a simple armamentarium for management of women complaining of urinary stress incontinence. Since history appeared to be not sufficiently reliable for management of patients, diagnosis was based mainly on cystomanometry and radiology. Of 58 women who have completed at least six months of follow-up, 11 had been diagnosed as suffering from detrusor instability (DI) and 47 from genuine stress incontinence (SI). Treatment was medical in the former group and surgical in the latter. Significant or complete relief of symptoms was reported in 91% of the former group and in 81% in the latter.
It was the aim of this study to evaluate critically the value of history in patients complaining of urinary stress incontinence. Diagnosis was established mainly by radiologic and cystomanometric assessment. History included 21 symptoms subdivided into various items. Only 3 symptoms were proven significant in distinguishing between various diagnostic groups. Assessment of stress incontinence should be regarded as incomplete without other means of evaluation in addition to history.
Nine cases of different types of anterior abdominal wall defects were diagnosed prenatally by ultrasound: gastroschisis (one case), omphalocele (five cases), exstrophy of the cloaca (one case) and the extreme form of prune belly syndrome (two cases). The ultrasonic features of gastroschisis and omphalocele are well recognized by most experienced sonographists. The ultrasonic prenatal diagnosis of exstrophy of the cloaca has not been reported previously and it is a very rare entity. The anterior abdominal wall defect is larger than in omphalocene and is located infraumbilically. Fetal ascites and a lumbosacral myelomeningocele are present as well. The extreme form of prune belly syndrome is associated with the absence of the abdominal wall musculature and marked dilatation of the urinary tract, presented ultrasonically as multiple large cysts occupying the distended fetal abdominal cavity. The differential diagnosis of these entities and guidelines for their correct prenatal ultrasonic diagnosis will be discussed.
We treated a case of congenital membranous stenosis of the esophagus successfully by transendoscopic incision. We discuss various types of true congenital esophageal stenosis and their treatment, to distinguish these rare anomalies from the more frequently encountered acquired variety.
Congenital anterior urethral diverticulum (AUD) is a rare condition. We report a case of AUD associated with urinary ascites, bilateral urinomas and dysplastic kidneys. The diagnosis of urethral obstruction was established in utero by means of ultrasound. The right perirenal urinoma appeared "septated", and we believe that this is related to its hemorrhagic content. Improvement of the clinical condition and renal function was noted after decompression by bilateral cutaneous loop ureterostomy.
Seventeen cases of different types of fetal thoracic and intrathoracic abnormalities were diagnosed prenatally by ultrasound: nonimmune hydrops (5 cases), diaphragmatic hernia (3), Potter's syndrome (3), chylothorax (1), exstrophy of the cloaca (1), the extreme form of prune-belly syndrome (2), cystic hygroma (1) and short rib polydactyly syndrome (Majevski type) (1 case). The ultrasonic features of nonimmune hydrops, diaphragmatic hernia, Potter's syndrome and cystic hygroma are well recognized by most experienced sonographers. The ultrasonic prenatal diagnosis of exstrophy of the cloaca, a very rare entity, has not been reported previously. The condition consists of a large infraumbilical anterior abdominal wall defect, lumbosacral myelomeningocele, and fetal ascites. The extreme form of prune-belly syndrome is associated with the absence of the abdominal wall musculature and marked dilatation of the urinary tract, presented ultrasonically as multiple large cysts occupying the distended fetal abdominal cavity. In exstrophy of the cloaca, prune-belly syndrome, Potter's syndrome and short rib polydactyly syndrome the chest abnormality is similar-extreme shortening of the thoracic cage, which has various causes. The differential diagnosis of all these entities and guidelines for their correct prenatal ultrasonic diagnosis are presented.
Cloacal exstrophy is a rare malformation, but most of its prominent structural features can be observed by detailed ultrasonography. Reported is a case in which the anomaly was diagnosed on prenatal scanning.
