2 months later
2 months later US in the transverse plane through the scrotal sac is dominated by a large complex loculated hydrocele compressing the enlarged right epididymis and testis.
Ashley Davidoff MD 133330
Doppler US in the sagittal plane through the right testis and epididymis shows normal vascularity to the testis and epididymis, both significantly compressed by a complex hydrocele.
Ashley Davidoff MD 133330
A Further 2 Months Later
2 months later US in the transverse plane through the scrotal sac is dominated by a large complex loculated hydrocele characterized by progressive thickening of the septations compressing the right testis.

These findings and the chronic history are most consistent with Tuberculous epididymitis

Epididymal Abscess

88 year old male presents with left scrotal pain and swelling

US in the sagittal plane through the right hemiscrotum shows a loculated collection in the left epididymis with compression of the left testis. Associated findings include overlying skin thickening.  These findings are consistent with an epididymal abscess
Ashley Davidoff MD 133175
US in the transverse plane through the left epididymis shows a multiloculated collection in the epididymis which extends through the tunica vaginalis into the surrounding soft tissues. Associated findings include overlying skin thickening. These findings are consistent with an abscess. A tumor of the epididymis is also included in the differential diagnosis as a less likely possibility.
