Diffuse Penile Metastasis from Prostate Carcinoma: A Rare Clinical Entity and MRI Diagnosis

Penile metastasis is typically linked to disseminated malignancy, leading to poor outcomes. We present an unusual case of penile metastasis from prostate cancer, diagnosed via Magnetic Resonance Imaging (MRI). Most metastatic tumors to the penis originate from genitourinary organs, followed by the recto-sigmoid region. Common clinical symptoms include penile pain, nodules, malignant priapism, skin lesions, and urinary disorders. While a diagnosis may be suspected based on history and a comprehensive physical examination, it necessitates confirmation through imaging, biopsy, and histopathologic examination. MRI serves as a valuable, non-invasive imaging technique, assisting in assessing the size, location, and extent of penile metastases, crucial for deciding between surgical or palliative treatment option.
