Posterior uveitis and primary cerebral reticulum cell sarcoma.

Primary cerebral reticulum cell sarcoma appeared as unexplained posterior uveitis. A retrospective review of 19 cases of cerebral reticulum cell sarcoma seen at Massachusetts General Hospital has not confirmed the previously described high incidence of ocular involvement in patients with this tumor. The presence of posterior uveitis remote from a definite cerebral mass should suggest the possible diagnosis of primary cerebral reticulum cell sarcoma.
