Kimura disease involving parotid gland and cervical nodes: CT and MR findings

Abstract

Kimura disease is a rare disease that occurs in Orientals. The majority of lesions occur in the head and neck and most patients have involvement of regional lymph nodes and the major salivary glands. We present a patient with parotid gland and submandibular lymph node involvement. On post-contrast CT the parotid gland enhanced intensely and the enlarged lymph nodes either enhanced diffusely or had rim enhancement. On MR the nodes had high T1-weighted and T2-weighted signal intensities as did portions of the parotid mass. There were suspected flow voids in the parotid mass. The clinical, pathological, and imaging findings are reviewed.
