case_images: A 64-year-old man who underwent radical cystectomy for bladder cancer 4 years ago. (a) Axial T2-weighted magnetic resonance image shows a large cyst extending along the proximal half of the penile shaft. Note the cyst includes septa (arrowheads) and solidified material (arrow). (b) Sagittal T2-weighted magnetic resonance image shows a large cyst extending along the proximal half of the penile shaft. Note the cyst includes septa (arrowhead) and solidified material (arrow).

case_images: Solidified material and septa, probably belonging to an organized hematoma, were noted within the cyst [Figure 1].
case_images: A 64-year-old man who underwent radical cystectomy for bladder cancer 4 years ago. (a) Axial contrast-enhanced fat-suppressed T1-weighted magnetic resonance image shows the enhancement of the urethra (red arrow) and cyst wall (green arrows). (b) Axial contrast-enhanced fat-suppressed T1-weighted magnetic resonance image shows the enhancement of the urethra (red arrow), penile crura (blue arrows), and the cyst wall (green arrows). (c) Axial contrast-enhanced fat-suppressed T1-weighted magnetic resonance image shows the enhancement of the cyst wall (green arrows).

case_images: The cyst wall, as well as the penile crura and residual urethra, showed enhancement following gadolinium administration [Figure 2].
case_images: A 64-year-old man who underwent radical cystectomy for bladder cancer 6 years ago and partial urethrectomy for urethral recurrence two years ago. (a) Sagittal T2-weighted magnetic resonance image shows a lobulated lesion in the penile root. (b) Sagittal fat-suppressed T2-weighted magnetic resonance image shows a lobulated lesion in the penile root.

case_images: The penile mass extended from the cystectomy stump posteriorly into the penile shaft, invading the penile crura, and urethra [Figure 3].
case_images: A 64-year-old man who underwent radical cystectomy for bladder cancer 6 years ago and partial urethrectomy for urethral recurrence two years ago. (a) Axial T1-weighted magnetic resonance image shows a heterogeneous mass extending along the proximal penile urethra (blue arrow). (b) Axial T2-weighted magnetic resonance image shows a heterogeneous mass extending along the proximal penile urethra (blue arrow). (c) Coronal fat-suppressed T2-weighted magnetic resonance image shows a lobulated mass with high signal extending along the proximal penile urethra (blue arrow). (d) Axial contrast-enhanced fat-suppressed T1-weighted magnetic resonance image shows the enhancement of the mass in the penile root (red arrow). (e) Axial contrast-enhanced fat-suppressed T1-weighted magnetic resonance image shows the enhancement of the mass in the penile shaft (red arrow).

case_images: T1-, T2-, and fat-suppressed T2-weighted sequences, consistent with a complex hemorrhagic cystic lesion. There was no anal canal or puborectal muscle invasion, but both corpora cavernosa were invaded. The mass exhibited intense heterogeneous enhancement following gadolinium administration [Figure 4].
case_images: A 64-year-old man who have undergone radical cystectomy for bladder cancer and partial urethrectomy and chemotherapy for urethral recurrence. (a) Coronal T2-weighted magnetic resonance image shows that the cyst has significantly enlarged and appears more infiltrative than before. (b) Sagittal T2-weighted magnetic resonance image shows that the mass has significantly enlarged and appears more infiltrative than before. (c) Axial T2-weighted magnetic resonance image shows that the mass has significantly enlarged. (d) Axial T2-weighted magnetic resonance image shows that the mass has significantly enlarged. (e) Axial T2-weighted magnetic resonance image shows that the mass has significantly enlarged. (f) Axial T2-weighted magnetic resonance image shows that the mass has significantly enlarged.

case_images: One year after the initiation of the chemotherapy, the pelvic MRI showed that the penile mass was now 62 x 46 x 30 mm (CC x AP x T) and appeared more infiltrative than it was a year ago [Figure 5].
case_images: A 64-year-old man who have undergone radical cystectomy for bladder cancer and partial urethrectomy and chemotherapy for urethral recurrence. Axial computed tomography image shows multiple metastatic pulmonary nodules (arrowheads).

case_images: In addition, thoracic computed tomography examination revealed multiple metastatic pulmonary nodules in both lungs [Figure 6].
