Abstract:
A case of Castleman disease in the anterior cervical region is presented. Ga-67 scintigraphy revealed moderate uptake in the thyroid region. Thyroid scintigraphy demonstrated the presence of an extrinsic thyroid tumor. Contrast-enhanced CT showed dense homogeneous enhancement within the tumor. Radionuclide tracer accumulation on gallium scintigraphy as well as dense contrast enhancement on CT scan may be characteristic of Castleman disease. Castleman disease should be considered in the differential diagnosis when increased tracer activity is noted in an anterior cervical extrathyroid tumor on Ga-67 scintigraphy.
