title: A case of thrombosis mimicking a buccal tumour: usefulness of MRI.
abstract: A rare case of thrombosis mimicking a tumour in the buccal region is reported. Since the entire round mass was located deeply, it was difficult to diagnose. Contrast computed tomography, magnetic resonance imaging (MRI) and ultrasound examinations may be useful, but MRI was most useful in this case because it allowed prediction of different kinds of histological structures in the soft tissue. The findings of T1 weighted imaging, T2 weighted imaging and examination with Gd-DTPA on T1 weighted imaging are useful for predicting the character of deeper soft tissue masses, and can differentiate thrombosis from lymphadenopathy, lipoma and other lesions.
