Intracranial meningiomas in children: report of 8 cases.

Background/aims: Meningiomas, although common in adults, are rare in infancy and childhood. We present a single institution experience of children with meningiomas and a comparison of our findings with other published data.

Methods: We reviewed the files of 352 children harboring a brain tumor, over a 16-year period.

Congenital cervical teratomas.

Congenital cervical teratomas are rare, representing 3% of teratomas in childhood. Although mostly benign, they are associated with a high mortality rate due to respiratory distress and require immediate surgical excision. The diagnosis is usually suggested on the physical examination.

Pleuropulmonary blastoma in the area of a previously diagnosed congenital lung cyst: report of two cases.

Pleuropulmonary blastoma (PPB) is a rare primary malignant pulmonary tumor in pediatric patients. We report the development of PPB in the area of a previous pulmonary cyst in two children, one boy and one girl 5 and 12 years old, respectively. We present the clinical and radiological findings.

Cystic dysplasia of the testis: a rare cause of painless hemiscrotal enlargement in childhood.

Cystic dysplasia of the testis is a rare, benign cause of painless hemiscrotal enlargement in children. We present two cases of cystic dysplasia of the testis presenting with scrotal enlargement. The diagnosis was based on its specific sonographic findings and on the coexistence of a multicystic dysplastic kidney in one case.

Perforation of multiple gastric duplication cysts: diagnosis by sonography.

A case of perforation of multiple gastric duplication cysts is presented. The rarity of this case is based on its multiplicity, its small size, its perforation into peritoneal cavity, as well as on the detection of tiny foci of ectopic pancreatic tissue at the site of perforation. The sonographic appearance and the clinical manifestations are discussed.

New sonographic appearance of hepatic mesenchymal hamartoma in childhood.

We present clinical, radiographic, and sonographic findings in 3 children with hepatic mesenchymal hamartoma, a rare benign tumor of childhood. The presence of round hyperechoic parietal nodules within the cystic spaces of the hamartomas is a new sonographic finding.

Torsion of an accessory hepatic lobe in a child: ultrasound, computed tomographic, and magnetic resonance imaging findings.

A case of acute epigastric pain resulting from torsion of an accessory hepatic lobe is reported. Sonographic, computerized tomographic, and magnetic resonance findings are illustrated and the surgical management is discussed.
