Two diagnoses can be contemplated in case of sudden, painful increase
in the volume of a testis : torsion of the spermatic cord and acute or
chiepididymitis. Two cases observed in young adults show that acute te
sticular ischemia may occur without any torsion of the cord, probably
due to sudden vascular occlusion. However, except in some unfrequent v
ascular diseases, the etiology of such accidents in young adults in go
od health is still mysterious. The loss of the involved testis is the
rule. Possibilities of treatment are limited at present and render the
prognosis for the testis very poor.
