Penile metastasis of malignant tumors is a very rare condition, often occurring as a part of systemic metastases, and is therefore associated with a poor prognosis. Although there have been reports of magnetic resonance imaging findings of penile metastasis, longitudinal imaging changes have not been presented previously. We report a case of a 80-year-old male patient with penile metastasis from prostate adenocarcinoma. First magnetic resonance imaging demonstrated multiple penile nodules in the left corpus cavernosum corpora cavernosa, and these nodules were fused and across the septum of the penis, forming an enlarged, diffusely spreading mass on the follow-up exam 5 years later. In this case, a longitudinal evaluation of magnetic resonance imaging demonstrated the course of the extension of the rare penile metastasis.
恶性肿瘤的阴茎转移是一种非常罕见的情况，通常作为全身转移的一部分出现，因此预后较差。尽管已有阴茎转移磁共振成像表现的报道，但此前尚未有纵向成像变化的相关报道。我们报告一例80岁男性前列腺腺癌阴茎转移患者。首次磁共振成像显示左侧海绵体有多个阴茎结节，5年后的随访检查中，这些结节融合并穿过阴茎隔膜，形成一个增大的、弥漫性扩散的肿块。在该病例中，磁共振成像的纵向评估显示了这种罕见阴茎转移的扩展过程。
