title: Cerebral lymphomatoid granulomatosis. A report of two cases, with disseminated necrotizing leukoencephalopathy in one.
abstract: Neuropathologic findings in 2 cases of cerebral lymphomatoid granulomatosis with sequelae are presented. A 30-year old male with macular rash and pulmonary lymphomatoid granulomatosis responded to Prednisone terapy but developed acute intracranial hypertension with coma. A necrotizing hemorrhagic lesion was evident in the left putamen surrounded by diffuse and perivascular atypical lymphoplasmacytic infiltration. An 18-year old girl developed pulmonary lymphomatoid granulomatosis, diplopia, slurred speech and right hemiparesis. Brain scan, angiography and EEG suggested a left fronto-parietal mass assumed to represent lymphomatoid granulomatosis. She responded well to cerebral irradiation, intrathecal methotrexate and cytoxan but relapsed with seizures and increasing respiratory insufficiency. At autopsy, stigmata of cerebral lymphomatoid granulomatosis were absent but a parenchymatous degeneration consistent with disseminated necrotizing leukoencephalopathy following antileukemic therapy in children, was found.
