Left testicular lesion RIGHT TESTIS: 4.2 x 2.2 x 2.9 cm. No intratesticular mass. Bilaterally symmetric Doppler flow characteristicsLEFT TESTIS: 4.3 x 2.1 x 2.8 cm. Bilaterally symmetric Doppler flow characteristics.There is a 0.6 x 0.5 x 0.4 cm well circumscribed mixed cystic and solid lesion inseparable from the left inferior mediastinum. This lesion demonstrates no appreciable vascularity. This lesion has not changed in its appearance when compared to 7/14/2014.RIGHT EPIDIDYMIS: No significant abnormalities noted.LEFT EPIDIDYMIS: No significant abnormalities noted.OTHER: No significant abnormalities noted.
Well-circumscribed mixed cystic and solid subcentimeter lesion inseparable from the left inferior mediastinum. This lesion demonstrates no appreciable vascularity and has not changed in appearance compared to 7/14/2014. An ultrasound report from 2002 provided by the patient documents the presence of a cystic lesion arising from the same left inferior mediastinum.Given this lesion's temporal stability from the prior study and a report from 2002 mentioning a cystic focus arising from the same the left inferior mediastinum location, a benign etiology is favored (such as a post inflammatory/fibrotic lesion.) The very minimal increase in size from 2002 and the presence of a complex mixed cystic and solid appearance compared to the cystic description in 2002 does not preclude a benign etiology and may represent expected evolution of a post inflammatory lesion. However, would recommend annual ultrasound surveillance monitoring of this lesion.
