Castleman's disease is a rare benign lymphangioproliferative disorder. The hyaline vascular subtype has a better outcome and is curable after surgical resection. Typically, Castleman disease manifests in the thorax, with rare reports of a renal hilum location. We present a 42-year-old male patient who had an incidentally detected right hilar hyaline vascular type of Castleman's disease, which we managed with surgical excision. Cross-sectional imaging modalities help in suggesting the diagnosis based on enhancement patterns and, more importantly, define the extent of the tumor pre-operatively. Although the renal hilum is a rare location for Castleman disease, it needs to be considered when imaging features suggest it.
