16-year-old girl with history of lymphatic malformation of the posterior left chest status post debulking. CHEST:LUNGS AND PLEURA: No significant abnormality of the lungs or pleura.MEDIASTINUM AND HILA: The heart and pericardium are normal. No mediastinal or hilar lymphadenopathy noted.CHEST WALL: A marker was placed over the palpable mass.A lobulated, T1 iso and T2 hyperintense mass measuring approximately 54 x 34 mm is seen within the left erector spinae musculature at the level of T9/T10 (series 601, image 22). This mass enhances and contains multiple flow voids on T2 weighted images. The mass extends anteriorly to the left T9 neural foramen (series 1505, image 255). A second mass with similar signal and enhancement characteristics is seen in the inferior latissimus dorsi. This mass measures approximately 39 x 19 mm (series 601, image 14) and extends through the chest wall but is extrapleural. A third, 12 x 9 mm mass is seen in the inferior left paraspinal musculature (series 601, image 4) with similar signal and enhancement characteristics. These masses appear to have increased in size and extent from the CT. Scattered foci of diffusion restriction are noted within these masses.Additional fat signal is seen throughout the left paraspinal and posterior chest wall musculature.Left thoracic curve noted. The spinal canal appears normal.UPPER ABDOMEN: The partially visualized liver, spleen, and kidneys appear normal. The gallbladder is normal.
Multiple masses in the left paraspinal and posterior chest wall musculature with signal and enhancement characteristics most suggestive of hemangiomas. These masses have increased in size compared to 2008.
