Successful sleeve lobectomy of pediatric inflammatory myofibroblastic tumor.

Inflammatory myofibroblastic tumor (IMT) is an uncommon solid tumor that was originally described in the lung. A 4-year-old girl was admitted to hospital with urticarial rash. On chest radiographs, an opacity was seen in the inferior zone of the left lung, and computed tomography showed a mass in the left lower lobe. Left lower sleeve lobectomy was performed, and the diagnosis was confirmed as IMT. Sleeve resection is the best option in lesions located in the mainstem bronchus or secondary carina. Herein, we present a rare case of IMT of the lung that was successfully treated with sleeve lobectomy. There have been fewer than 15 childhood cases of IMT reported in the literature, and the present 4-year-old patient is one of the youngest.

Extraspinal Incidental Findings on Routine MRI of Lumbar Spine: Prevalence and Reporting Rates in 1278 Patients.

OBJECTIVE: The aim of the present study was to determine the prevalence and reporting rate of incidental findings (IF) in adult outpatients undergoing lumbar magnetic resonance imaging (MRI). MATERIALS AND METHODS: Re-evaluation of a total of 1278 lumbar MRI images (collected from patients with a mean age of 50.5 years, range 16-91 years) captured between August 2010-August 2011 was done by a neuroradiologist and a musculoskeletal radiologist. IFs were classified according to organ or system (liver, gallbladder, kidney, bladder, uterus, ovary, lymph node, intestine and aorta). The rate of reporting of a range of IF was examined. The outcome of each patient's treatment was evaluated based on review of hospital records and by telephone interviews. RESULTS: A total of 253 IFs were found in 241 patients (18.8% of 1278). Among these, clinically significant IFs (n = 34) included: 2 renal masses (0.15%), 2 aortic aneurysms (0.15%), 2 cases of hydronephrosis (0.15%), 11 adrenal masses (0.86%), 7 lymphadenopathies (0.55%), 6 cases of endometrial or cervical thickening (0.47%), 1 liver hemangioma (0.08%), 1 pelvic fluid (0.08%) and 2 ovarian dermoid cysts (0.15%). Overall, 28% (71/253) of IFs were included in the clinical reports, while clinically significant findings were reported in 41% (14/34) of cases. CONCLUSION: Extraspinal IFs are commonly detected during a routine lumbar MRI, and many of these findings are not clinically significant. However, IFs including clinically important findings are occasionally omitted from formal radiological reports.
