Osteoclastoma-like giant cell tumor of the renal pelvis, similar to the entity more commonly occurring in bone, is very rare, having been reported in twelve previous cases to our knowledge. This is the first report of this entity, to our knowledge, to include its cross-sectional imaging appearance. A hyperdense area within the lesion on non-contrast CT may correspond with extensive hemorrhagic content of the lesion identified histologically. As in most prior cases, an adjacent smaller urothelial carcinoma of the renal pelvis was also identified. In the limited reported cases, this entity has exhibited highly aggressive behavior with poor prognosis.
肾盂骨巨细胞瘤样肿瘤，类似于更常见于骨骼的实体，非常罕见，据我们所知，以前已有 12 例报道。据我们所知，这是该实体的首次报告，包括其横断面成像表现。病变在非增强 CT 上的高密度区域可能与组织学上确定的病变广泛出血内容相对应。与大多数先前的病例一样，还发现了一个相邻的较小的肾盂尿路上皮癌。在有限的报告病例中，该实体表现出高度侵袭性行为和不良预后。
