    Castleman's disease as cervical mass: a report of three cases and review of the literature
    (Cic Edizioni Int, 2009) Cakabay, B.; Akbulut, S.; Sezgin, A.; Gomceli, I.; Arikok, A. T.; Ozmen, C. Akgul; Ozbek, E.
    node hyperplasia involving lymphatic tissue in the neck, mediastinum, abdomen and other areas. Disease was described for the first time in 1956 by Castleman. The etiopathogenesis of the disease is unknown. The disorder can be classified into three histopathological types: hyalin-vascular, plasma-cell and mixed. We report three cases of the Castleman's disease (hyaline-vascular type) in three female patients with unilateral swelling of the neck. None of the patients developed any local or distant recurrence in postoperative follow-up.

    Visualization of the normal appendix in children by non-contrast MDCT
    (Acta Medical Belgica, 2007) Akay, H. Ozturkmen; Akpinar, E.; Ozmen, C. Akgul; Ergun, O.; Haliloglu, M.
    Objective : We studied the proportion of normal appendices, identified on non-contrast MDCT scans of the abdomen and pelvis in children with possible renal stones. Materials and methods : A total of 105 patients were included in the study, comprising 40 girls (38%) and 65 (62%) boys, with a mean age of 7.3 years. Non-enhanced abdominal computed tomographies were evaluated retrospectively, and the visualization, location, contents, diameter of the appendix, and the amount of abdominal fat were recorded. Results : The appendix was clearly distinguished in 72 patients (68.5%). The difference in appendix visualization rates between patients with low and medium amounts of abdominal fat was statistically significant (p < 0.001). Visualization increased with age. The greatest external diameter was between 2.8 and 10 mm, with a mean of 5 +/- 1.34 mm. Conclusion : MDCT without contrast will be more useful when used in patients of 6 years old and over, for visualization of the appendix. A better visualization of retrocaecal appendix by MDCT provides a greater advantage over US. Prospective comparative studies will determine the role of this method in the diagnosis of acute appendicitis in pediatric patients.
