Abstract

This article aims to evaluate the Magnetic Resonance Imaging (MRI) semeiotic aspect of an intramuscular hemangioma in the masseter of two patients and review the literature regarding the diagnostic possibilities of MR imaging in interpreting the characteristics of benign and malignant types of this intramuscular lesion in order to ensure a correct diagnosis and treatment. Two patients, aged 29 and 25 years, underwent an MRI examination using a 1.5 Tesla superconducting magnet (Siemens, Erlangen, Germany), with a dedicated surface coil, in one case before and after administering a paramagnetic contrast agent (gadolinium). In both cases, MRI showed the intramuscular haemangioma both with and without the use of the paramagnetic contrast agent. MR images, taken before and after administering the paramagnetic contrast agent, provide important information about the type of intramuscular lesion analyzed, by which it is possible to differentiate a benign mass from a malignant one.
