The occurrence of PVNS in the TMJ is very rare. We report a case of PVNS which
was misdiagnosed as a parotid tumor at first. CT and conventional radiograph revealed
a well defied mass demonstrating higher attenuation than adjacent soft tissue. Erosion
and expansion of the cortical plate of the mandibular condyle and sclerotic change
beneath the margin of the lesion were also shown. MRI demonstrated well defined mass
of very low signal intensity on both T1 and T2-weighted images due to ferromagnetic
effect of the high concentrated hemosiderin and clearly delineated the extent of the
lesion. Histopathologic findings and characteristic appearance of the various imaging
methods were described and the usefulness of these images for diagnosis and
pretreatment evaluation of PVNS were also discussed.
