Patient Data

Urgent US not available had revealed an intracavernous mass without blood flow ? neuroma. MRI for clarification
Well-defined mass in the proximal right corpus cavernosum. Note mass is bright on T1 = methemoglobin with minor peripheral enhancement. Swollen right corpus caused extrinsic compression to the left
Case Discussion
Partial thrombosis of the corpus is rare and often well-defined (as in this case) due to the segmental nature of the corpus whereby there appears to be a septum dividing it into proximal and distal portions (proximal always seems to be involved). Microtrauma (at intercourse) is believed to be responsible for the development of thrombus. Treatment is expectant and usually successful with spontaneous resolution. MRI is helpful for diagnosis (as in this case) due to the presence of T1 hyperintensity = methemoglobin and absence of enhancement as might occur in a solid mass lesion.
