MR imaging of pancreatic changes in patients with transfusion-dependent β-thalassemia major
OBJECTIVE. The aim of this study was to evaluate MR imaging changes of the pancreas in patients with transfusion-dependent β-thalassemia major. SUBJECTS AND METHODS. Twenty patients with transfusion-dependent β- thalassemia major were examined using MR imaging at 0.5 T, with spin-echo T1- weighted, fast spin-echo T2-weighted, and gradient-echo T2*-weighted sequences. Image analysis was performed to assess pancreas-to-fat signal intensity ratios for all pulse sequences. Pancreatic exocrine and endocrine function and serum ferritin levels were assessed. Twenty healthy volunteers underwent MR imaging with the same three sequences and served as a control group. RESULTS. The pancreas-to-fat sign…
Teratoma with a malignant somatic component in pediatric patients: The Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) experience
BACKGROUND: Teratoma with a malignant somatic component (TMSC) is rare but described in adults, whereas information on pediatric presentation is sparse. PROCEDURE: The Associazione Italiana Ematologia Oncologia Pediatrica identified 14 cases of TMSC. Clinical files and pathology specimens were reviewed. RESULTS: The series (9 female, 5 male) showed the following disease: testis (2), sacrococcygeal (3), ovary (3), retroperitoneum (3), mediastinum (2), and foot soft tissue (1). Distribution of the somatic component was: carcinoma (4), pancreatic neuroendocrine tumor (1), neuroblastoma (3), rhabdomyosarcoma (3), rhabdomyosarcoma plus liposarcoma, chondrosarcoma, neurogenic sarcoma (1), chondro…
