Spontaneous regression of primary malignant intracranial lymphoma.
A rare case of intracranial multiple tumor, which disappeared spontaneously on serial cranial computed tomography (CT) scans, is described. The initial CT scan showed multiple, well-enhanced lesions in the right frontal and parietal lobes. The lesions disappeared spontaneously without any treatment during the 2 following months of observation. One month later, however, a newly formed tumor was found on serial CT-scanning. Surgical intervention confirmed the histologic diagnosis of a non-Hodgkin's, large, and diffuse-type malignant lymphoma. The possible mechanism of temporal disappearance of tumors on CT scanning is discussed.
