Partial thrombosis of the corpus cavernosum - a malignancy mimicker

Catarina Ala Baraças et al. BJR Case Rep. .

Abstract

Partial thrombosis of the corpus cavernosum is a rare condition, typically seen in young patients. Etiology, physiopathology and treatment are still not entirely understood. The authors report a case of a 49-year-old male with gastric cancer, who successfully treated a thrombosis of the corpus cavernosum conservatively. Diagnostic considerations and treatment options are discussed.

Figures

Figure 1.
Figure 1.
Non-contrast CT (1a) shows an asymmetrical enlargement of the proximal segment of the right corpus cavernosum. In contrast-enhanced CT (1b), the mass remains hypodense with a hyperdense rim of enhancement, causing mass effect on the left corpus cavernosum.
Figure 2.
Figure 2.
Ultrasound (2a, 2c) at the base level of the penis revealed a well-circumscribed right-sided corpus cavernosum, enlarged and round-shaped, with heterogeneous decreased echogenicity. Doppler ultrasound (2b, 2d) showed no vascularity inside the abnormal image.
Figure 3.
Figure 3.
MRI (1.5 T) at the base of the penis. Axial view T1 weighted image shows the enlarged right corpus cavernosum, which is T1 hyperintense (*) comparing to the surrounding corpora. The left corpus cavernosum is displaced and compressed.
Figure 4.
Figure 4.
Axial T2 weighted FatSat (4a) and T2* images (4b) demonstrate iso/hyperintensity of the thrombus, due to extracellular methemoglobin. There is a membrane in the distal boundary of the thrombus displaying a low signal (arrow). There is a similar membrane in the contralateral corpus cavernosum (arrowhead).
Figure 5.
Figure 5.
Sagittal (5a) and coronal (5b) T1 weighted images with gadolinium contrast-enhanced demonstrate a lack of enhancement of the thrombosed right-sided corpus cavernosum, with a rim enhancement.
