We report a case with double primary intracranial tumors of different cell types without phacomatosis. The patient was hospitalized due to progressive memory impairment, headaches, dysarthria and right hemiparesis. Initial computed tomographic (CT) examinations revealed a large hyperdense tumor over the right frontal lobe, suggestive of an extra-axial meningioma. Additionally, there was unusual brain edema in the contralateral hemisphere that subsequently proved to originate from an intrinsic tumor. Staged craniotomies were used to treat the patient. Pathological examinations confirmed the two tumors to be a meningioma and a glioblastoma multiforme, respectively. The patient made an uneventful recovery after treatment. Although meningioma and glioma represent two common primary intracranial tumors, the simultaneous development of the two tumors is rare. A randomly occurring event most likely accounted for this linkage in the patient. We suggest that extraordinary brain edema far remote from the primary brain lesion warrants special attention for identifying other potentially undetected lesions.

Three patients, two women aged 72 and 45 years, and a man aged 80 years, presented with transient neurological deficits due to a brain tumour, a glioblastoma multiforme and two meningiomas respectively. A fourth patient, an 84-year-old man, had a transient ischaemic attack (TIA) with a meningioma as an incidental finding. The first woman had normal CT findings, but MRI revealed the neoplasm. Symptoms included motor loss, sensory disturbances, dysphasia and dysarthria, lasting from 30 seconds up to 10 minutes. The first two patients had surgery; the first one later died when the tumour recurred. The other two patients still exhibit a spontaneous recovery. Of all patients with a clinical presentation of a TIA, 0.4-1% harbour a brain tumour. Clinical symptoms do not distinguish 'transient tumour attacks' from TIAs with a primarily vascular origin. Transient tumour attacks are mainly seen with meningiomas, and to a lesser extent with high-grade gliomas. Changes in intracranial pressure leading to focal ischaemia may explain the occurrence of this phenomenon. A part from intracerebral tumours, non-vascular entities mimicking TIAs can also be seen with demyelinating processes, metabolic disturbances, epilepsy or migraine. Brain imaging is always required in patients with transient neurological deficits. A CT scan may provide false-negative results and in case of doubt, MRI is the preferred diagnostic tool.

October 2004. A 49-year-old right-handed man developed progressive cognitive difficulties over a 4-month period. There was impairment in recent memory, calculations and language. He also developed fatigue, weight loss, gait imbalance and urinary incontinence. Past history included transfusion-associated Hepatitis C. Neurologic exam showed mild dysarthria, dysnomia, left sided neglect, bilateral Babinski signs, and a prominent grasp reflex. Laboratory testing provided no positive etiologic data. An EEG showed generalized intermittent slowing suggestive of a diffuse encephalopathy and decreased background in the right hemisphere, suggestive of a structural lesion. MRI showed multiple areas of high signal on FLAIR imaging and patchy enhancement. FDG-PET showed multi-focal areas of increased uptake, correlating with the abnormal areas on MRI, on a background of decreased uptake. A 4-vessel cerebral angiogram showed no abnormalities. A brain biopsy showed diffuse infiltrates of large malignant cells that were immunoreactive with antibodies to CD20, diagnostic of diffuse large B cell lymphoma. In summary, the clinical presentation suggested bilateral hemispheric involvement, which was supported by physical examination, EEG, MRI, and PET scans. The differential diagnosis for this presentation is limited to demyelinating disease such as multiple sclerosis, vascular dementia, and infiltrating neoplasm such as glioblastoma multiforme or lymphoma. Diagnosis was made by morphologic and immunohistochemical analysis of brain tissue.

A rare case of simultaneous occurrence of three entirely distinct intracranial tumors is described. A 55-year-old male with no evidence of phacomatoses or history of radiation therapy presented with complaints of increased drowsiness, headaches, and dysarthria. Investigations revealed an olfactory groove meningioma, a glioblastoma multiforme in the left medial temporal lobe, and a diffuse glioma in the brain stem. Occurrence of multiple varieties of tumors at the same time is extremely rare. Theories that explain their occurrences including the role of common carcinogens, autocrine growth factors, and tumor suppressor genes are discussed.
