Two new cases of pediatric tumoral calcinosis.

Tumoral calcinosis (TC) is a rare benign pathology, particularly in pediatrics. It is difficult to diagnose with its pathophysiology poorly understood. We report two pediatric cases of TC having benefited from radiological assessments and surgical excision. Final diagnosis was made by pathological examination. For the two cases, no sign of recurrence was noted ~30 months of follow-up.

Contribution of Scanopelvimetry in the Prognosis of Childbirth.

Objectives To determine the frequency of the demand of radiopelvimetry in pregnant women and to assess the obstetrical prognosis. Methods Retrospective study about 19 months, including a total of 45 pregnant women who underwent scanopelvimetry to evaluate the biometry of the pelvis. Scanopelvimetry was performed from 36th week of pregnancy. Results The average age of the patients was 26.9 years. The frequency of the demand of scanopelvimetry was 0.97%. The height of the patients was greater than 150 cm in 84.44%. The indications of radiopelvimetry were dominated by the clinical suspicion of pelvic narrowing (57.78%), followed by the cephalopelvic confrontation (33.33%) and the cicatricial uterus (8.89%). Narrowed pelvis was observed in 28.89% of cases (13/45), with a Magnin index of less than 21. A caesarean section during labor was performed in 24.44% of the cases. No death of newborn was reported. Conclusion The frequency of the demand of scanopelvimetry is low but the rate of surgical pelvis is high among suspect cases.

Atypical alveolar proteinosis.

Alveolar proteinosis is a rare pulmonary disease characterized by intra-alveolar accumulation of surfactant composed of lipoproteinaceous material, related to a lack of surfactant resorption by alveolar macrophages. Crazy paving pattern is characteristic, but not specific. The multinodular forms of this affection remain exceptional.

Endoscopic treatment of vesicoureteral reflux--a 20-year follow-up.

Endoscopic reflux therapy has gained more and more popularity, and the use of this method is increasing. These imaging patterns (well known by pediatric radiologists) should be known by the general radiologist as the first young patients treated 20 years ago are now adults.

Giant ameloblastoma.

Ameloblastoma is the most frequent of the odontogenic tumors. We report a case of a giant ameloblastoma involving the maxillary region and describe its ultrasonography and computed tomography findings.
