MRI and suspected acute pyelonephritis in children: comparison of diffusion-weighted imaging with gadolinium-enhanced T1-weighted imaging.

Objectives: To evaluate the performance of diffusion-weighted imaging (DWI) against the reference standard of gadolinium-enhanced T1-weighted imaging (Gd-T1-WI) in children.

Methods: Thirty-nine consecutive patients (mean age 5.7 years) with suspected acute pyelonephritis underwent magnetic resonance imaging (MRI) including DWI and (the reference standard) Gd-T1-WI.

Idiopathic varicocele in adolescents: risks of the inguinal approach.

Introduction: The aim of this study was to evaluate the medium-term results and complications of open inguinal varicocelectomy, including vein ligation, intraoperative venography, and antegrade sclerotherapy.

Materials And Methods: Sixty-four children were treated between 2000 and 2009 for idiopathic varicocele. Fifty children were examined 6 months after surgery.

Imaging of a primitive clitoral epidermoid cyst.

An 11-year-old Caucasian girl was investigated for a clitoromegaly that had increased in size over 5 weeks. Clitoromegaly is a rare condition in childhood. Among nonhormonal causes are tumours, both benign and malignant.

Uterus didelphys, hemihydrocolpos and empty ipsilateral lumbar fossa in a newborn girl: involuted dysplastic kidney rather than renal agenesis.

We report a case of Herlyn-Werner-Wunderlich syndrome diagnosed in the neonatal period. US revealed the classic association of a uterus didelphys with blind hemivagina and no ipsilateral kidney. The diagnosis was established by postnatal US and confirmed by MRI.
