[Show abstract][Hide abstract] ABSTRACT: To assess the prevalence and morphologic characterization of pulmonary nodules in children on a chest computed tomography (CT).
Two hundred and fifty-nine trauma chest CTs in children aged 0-18 years were retrospectively reviewed by two radiologists, each with more than 10 years of experience. Images were acquired on a 64-row CT. Pulmonary lobes with trauma affections such as contusion or haemorrhage were excluded. All pulmonary nodules were evaluated for distance from the pleural surface, location, calcification and size on axial slices.
A total of 1,190/1,295 (92 %) pulmonary lobes without traumatic injury were included in this study. In 86 of 259 (33 %) patients, 131 pulmonary nodules were detected. Number of nodules per patient ranged from 1 to 4. Calcifications were seen in 19 % (25) of all nodules. Diameters ranged from 1 to 5 mm. 59 % (77) were located in the lower lobes, 9 % (12) in the middle lobe and 32 % (42) in the upper lobes. 84 % of the non-calcified nodules >2 mm showed a slightly angular or triangular (mostly pleural nodes) shape.
Pulmonary nodules smaller than 5 mm can be detected frequently in children without malignant disease and are predominantly located in the lower lobes.
• Pulmonary nodules in children with trauma CTs were retrospectively analysed • Pulmonary nodules seen on CT are frequent in children without malignant disease • Nodules in this group are more frequent in the lower lobes • No age dependency for the number of pulmonary nodules in children was observed.

[Show abstract][Hide abstract] ABSTRACT: Primary thoracic wall malignancy is a rare and diverse entity in children. Surgical treatment commonly involves major chest wall resection causing large defects requiring complex reconstruction. In adults, the use of alloplastic and/or xenogenic materials and muscle flap repair is well established. However, literature provides only little information on procedures in children. We report our experience in 8 consecutive children who underwent chest wall resection and reconstruction with regard to surgical treatment and outcome.
Retrospective study of all children with primary malignant chest wall tumors requiring rib resection and reconstruction with prosthetic material performed in our institution between November 2002 and April 2010. Endpoints were postoperative complications and long-term results, focusing on scoliosis defined radiologically by the Cobb angle.
8 children (7 male, 1 female) with a median age of 10.6 (4.1-18.9) years underwent resection of thoracic wall tumors. A mean number of 3 (1-5) ribs were resected. Stability was obtained using rigid prosthetic material (STRATOS™ titanium bar) in 2 patients and/or non-rigid prosthetic material (Goretex® patch in 6 patients, Vicryl® patch in 3 patients, Tutopatch® in 1 patient). A muscular flap was added in 5 patients. Postoperative complications included superficial wound infection (n = 2) and dislocation of a titanium bar necessitating removal in 1 patient. No infections of the prosthetic material were observed. No perioperative mortality occurred. At a mean follow-up of 37.5 (4-97) months, 6 patients were alive. 2 patients died due to early tumor recurrence. Mild scoliosis (Cobb angle 10-20°) was detected in 2 of the surviving patients (33%).
Surgical reconstruction after resection of malignant thoracic wall tumors using non-rigid prosthetic material is safe and effective in pediatric patients, whereas rigid prosthetic material might dislocate. Scoliosis represents a long-term complication after chest wall reconstruction and should be monitored during routine follow-up.
