文摘

Intramuscular nodules can be the clinical presentation of several groups of lesions, such as reactive disorders and benign and malignant tumors. Here, we present three cases with similar clinical features and image aspects on Doppler ultrasonography. Two of the lesions were diagnosed as intramasseteric hemangioma and the third as intramasseteric metastasis from high-grade pleomorphic sarcoma of the thigh. The diagnosis of intramasseteric nodules is challenging, and various differential diagnoses must be considered. Clinical features, evolution time, and information from complementary examinations, such as Doppler ultrasonography and fine-needle aspiration cytology, are useful in making a precise diagnosis and providing appropriate treatment.
