4-year-old female with right chest wall swelling and lymphatic malformation. Evaluate structure and extent of the malformation. Well encapsulated right chest wall mass with intermediate T1 and high T2 signal demonstrating minimal delayed enhancement measures 5.2 x 4.9 x 2.3 cm (coronal series 401, image 20; axial series 501 image 20), previously measuring 5.7 x 2.5 x 3.8 cm. This mass is a slightly different orientation than on prior exam and measurements are made in a slightly different orientation. The mass is now more rounded in the axial plane and previously appeared more triangular. The difference in orientation may be secondary to positioning during imaging or possibly differential growth. Again seen are T2 hypoattenuating serpentine signal voids within the mass. No restricted diffusion to suggest abscess. No additional lesions are identified. No abnormal signal seen within the adjacent osseous structures.
Well encapsulated right chest wall heterogenous mass with minimal delayed enhancement likely representing a lymphangioma is in a slightly different orientation than on prior exam.
