From: Role of diffusion-weighted MRI in evaluation of pediatric musculoskeletal soft tissue masses
A 3-month-old female patient, presented with a large mass at the left axilla. A, B Coronal T1WI and coronal T1WI with contrast: A large well-defined lobulated soft tissue mass of low signal intensity is seen involving predominantly the left axillary region and compressing chest wall posteromedially with no intervening fat planes between the mass and left lung apex. It is seen lateral abutting head of humerus with areas of cystic necrosis appear as small foci of low signal intensity. Heterogeneous enhancement noted in post-contrast series. C, D Coronal T2WI and coronal STIR: The mass shows heterogeneous high signal with small foci of high signal intensity representing areas of break down. E Axial DWI: The mass elicits high signal intensity. F Axial ADC map: The mass elicits low signal intensity with a mean ADC value of solid portion (0.681 × 10–3 mm2/s). Pathological result was a case of rhabdomyosarcoma
