Purpose To evaluate the clinical significance of indeterminate pulmonary nodules at diagnosis (defined as ≤ 4 pulmonary nodules < 5 mm or 1 nodule measuring ≥ 5 and < 10 mm) in patients with pediatric rhabdomyosarcoma (RMS). Patients and Methods We selected patients with supposed nonmetastatic RMS treated in large pediatric oncology centers in the United Kingdom, France, Italy, and the Netherlands, who were enrolled in the European Soft Tissue Sarcoma Study Group (E pSSG) RMS 2005 study. Patients included in the current study received a diagnosis between September 2005 and December 2013, and had chest computed tomography scans available for review that were done at time of diagnosis. Local radiologists were asked to review the chest computed tomography scans for the presence of pulmonary nodules and to record their findings on a standardized case report form. In the E pSSG RMS 2005 Study, patients with indeterminate pulmonary nodules were treated identically to patients without pulmonary nodules, enabling us to compare event-free survival and overall survival between groups by log-rank test. Results In total, 316 patients were included; 67 patients (21.2%) had indeterminate pulmonary nodules on imaging and 249 patients (78.8%) had no pulmonary nodules evident at diagnosis. Median follow-up for survivors (n = 258) was 75.1 months; respective 5-year event-free survival and overall survival rates (95% CI) were 77.0% (64.8% to 85.5%) and 82.0% (69.7% to 89.6%) for patients with indeterminate nodules and 73.2% (67.1% to 78.3%) and 80.8% (75.1% to 85.3%) for patients without nodules at diagnosis ( P = .68 and .76, respectively). Conclusion Our study demonstrated that indeterminate pulmonary nodules at diagnosis do not affect outcome in patients with otherwise localized RMS. There is no need to biopsy or upstage patients with RMS who have indeterminate pulmonary nodules at diagnosis.

Tomography Appearance

Congenital perilymphatic fistula is an abnormal communication between the inner ear and middle ear. Inner ear anomalies have been described on computed tomography scans. Middle ear anomalies have been found at surgery; the most frequent are anomalies of the stapes and round window. This retrospective study describes the appearance of the inner and middle ear on computed tomography scans, and of the middle ear at surgery, in 10 patients (15 ears) in whom perilymphatic fistula was found at surgery. Twelve of 15 stapes were abnormal at surgery; 4 of these 12 (33%) could be seen on computed tomography scans. Two stapes normal at surgery were normal on computed tomography. Three round windows were abnormal at surgery; none of these was seen on computed tomography scans. There were also four dysplastic cochleas, four dysplastic vestibules, and three dilated vestibular aqueducts. Computed tomography scans identified an abnormal inner ear, middle ear, or both in 8 (53%) of the 15 ears with perilymphatic fistula. An inner ear or middle ear anomaly on computed tomography may heighten clinical suspicion of congenital perilymphatic fistula.

Abstract Objective: To describe the main tomography findings in patients diagnosed with pulmonary infection caused by Mycobacterium kansasii. Materials and Methods: Retrospective study of computed tomography scans of 19 patients with pulmonary infection by M. kansasii. Results: Of the 19 patients evaluated, 10 (52.6%) were male and 9 (47.4%) were female. The mean age of the patients was 58 years (range, 33-76 years). Computed tomography findings were as follows: architectural distortion, in 17 patients (89.5%); reticular opacities and bronchiectasis, in 16 (84.2%); cavities, in 14 (73.7%); centrilobular nodules, in 13 (68.4%); small consolidations, in 10 (52.6%); atelectasis and large consolidations, in 9 (47.4%); subpleural blebs and emphysema, in 6 (31.6%); and adenopathy, in 1 (5.3%). Conclusion: There was a predominance of cavities, as well as of involvement of the small and large airways. The airway disease was characterized by bronchiectasis and bronchiolitis presenting as centrilobular nodules.
