Primary calcification in post-transplantation lymphoproliferative disorder involving the hepatic graft: an exceptional finding.

Calcification within active post-transplantation lymphoproliferative disorders has, to our knowledge, never been described. We report the case of a 14-month-old boy who presented 4 months after orthotopic liver transplantation with a primary calcification in a lymphoproliferative nodule involving the hepatic graft. This calcification was detected by routine ultrasonography, visible on plain radiographs, and the post-transplantation lymphoproliferative disorder was histologically proved.

Radiographic skeletal survey and radionuclide bone scan in Langerhans cell histiocytosis of bone.

BACKGROUND: The lack of a consensus in the literature on the imaging strategy in Langerhans cell histiocytosis (LCH) bone lesions in childhood. OBJECTIVE: To evaluate the relative value of radionuclide bone scan (RBS) and radiographic skeletal survey (RSS) in the detection of LCH bone lesions, both in the initial work-up of the disease and during the follow-up period. MATERIALS AND METHODS: Ten children with bone lesions evaluated by means of RSS and RBS in a retrospective study (1984-1993). RESULTS: Fifty radiologically and/or scintigraphically abnormal foci were detected: 27 anomalies in the initial work-up (12 by both RSS and RBS, 8 by RSS only and 7 by RBS only) and 23 additional anomalies during follow-up (10 by both RSS and RBS, 10 by RSS only and 3 by RBS only). RSS+/RBS- lesions (n = 18) are more frequently encountered in the skull (P = 0.038), and more frequently lack radiologic signs of osteoblastic activity (P = 0.020), than RSS+/RBS+ lesions (n = 22). RSS-/ RBS+ abnormalities (n = 10) were most frequently insignificant. CONCLUSION: In the initial work-up both RSS and RBS should be carried out, while in the follow-up only RSS should be performed.

[The role of ultrasonography in abdominal pain in children in the emergency room].

Our retrospective study aims at defining the influence of ultrasonography on the management of acute abdominal pain in a pediatric population. This technique appears to be essential in the diagnosis of intussusception and thus, should be recommended in all cases of acute abdominal pain in the population at risk for this disorder. On the other hand, ultrasonography only plays a minor role in the management of the other diseases we observed, especially in acute appendicitis.
