title: Imaging and clinical spectrum of rhabdomyosarcoma in children.
abstract: We retrospectively analyzed the MRI findings of rhabdomyosarcoma (RMSA) in 23 patients to evaluate its role in staging and management. Heterogeneous signal abnormalities were noted in the sarcoma lesions with significant contrast enhancement. Seven head and neck cases showed direct bone invasion and destruction; only one had distant bony metastasis. Metastasis was noted in the lymph nodes, lung, bone, abdominoperitoneum, and head and neck soft tissue. MRI findings of RMSA are most helpful in staging and assessing therapeutic response.
