Medullary sponge kidney (MSK) is an uncommon kidney malformation, characterized by cystic dilatation of the precalyceal papillary collecting ducts. Urography and computed tomography scan represent the gold standard to detect this congenital disorder. A clear diagnosis is not always feasible, especially in the presence of a concomitant renal mass, which in turn can be difficult to detect in MSK patients. When conventional imaging is inconclusive, a renal biopsy can be considered in doubtful cases. Here, we report a unique case of a Bellini duct carcinoma in a patient with MSK and we review the literature on this complex condition.
髓质海绵肾（MSK）是一种罕见的肾脏畸形，其特征为肾小盏乳头集合管囊状扩张。尿路造影和计算机断层扫描是检测这种先天性疾病的金标准。明确的诊断并不总是可行的，特别是在存在并发肾肿块的情况下，而在 MSK 患者中，这种肿块又很难被发现。当常规影像学检查不明确时，在可疑病例中可考虑进行肾活检。在这里，我们报告了一例 MSK 患者合并 Bellini 导管癌的独特病例，并对这一复杂情况的文献进行了回顾。
