The case of a 43-y-old healthy woman presenting with spontaneous splenic ru
pture is reported. The outcome was favourable after splenectomy. Although t
he diagnosis of CMV infection was established by serology, PCR and immunost
aining, no viral inclusions were observed on spleen sections. The pathophys
iology of the lesions was unclear given the multiple interactions of the vi
rus with various cell populations, and particularly with the immune system.
