Diagnostic approach to intramasseteric nodules

Abstract Background Intramuscular nodules can be the clinical presentation of several groups of lesions such as reactive disorders, benign and malignant tumors. Cases Herein we present three cases with similar clinical features and image aspects in Doppler ultrasonography. Two of them were diagnosed...

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