CT - TESTICULAR MASS


The preferred method of evaluating testicular mass is using Ultrasound.

But weve got a CT pelvis showing a left testicular mass.
Since 25% of testicular tumor seminoma  present with metastases, it is good to have a CT when testicular tumour is suspected on USG.


DIFFERENTIAL DIAGNOSIS of testicular mass
1.Testicular Tumors
2.Testicular Cyst
3.Testicular abscess

TESTICULAR TUMORS


1.GERM CELL TUMOUR  - 95%
A.SEMINOMA - 50% OF GCT
Most common Testicular Cancer
Most common cancer in undescended testes

B.EMRYONAL CARCINOMA - 25% OF Germ cell tumor
More aggressive than seminomas

C.CHORIOCARCINOMA
D.TERATOMA



2.NON GERM CELL TUMORS 
SERTOLI CELL TUMORS - secretes oestrogens
LEYDIG CELL TUMOR - secretes  testosterone

3.METASTASIS : Most common tumors in males > 50 years
