Two hundred and twenty-seven cases of carcinoma metastatic to the eye and orbit have been reviewed previously. The orbit alone was involved in 28 cases: theses lesions constitute the basis of this clinicopathologic study. The most common signs and symptoms produced by orbital metastasis included exophthalmos (75%1, pain (29%), decreased vision (29%), periorbital swelling (25%), a visible mass (21%), ophthalmoplegia, and diplopia (18%). The ophthalmologists' preoperative (or premortem) clinical diagnoses were: orbital mass, 36%; metastatic carcinoma, 29%; leukemia, 7%; melanosarcoma, 4%; mixed tumor of lacrimal gland, 4%; and meningioma, 4%. The sites of the primary tumors in the 28 patients with orbital metastasis were as follows: breast, eight; lung, four; genitourinary tract, four; pancreas, one; and ileum, one. In 10 patients the site of the primary carcinoma was not determined. In 17 of the 28 patients, symptoms of orbital metastasis preceded detection of a primary tumor elsewhere in the body. In 10 of the remaining 11 patients, detection of the primary tumor had preceded the onset of orbital symptoms. In one patient, symptoms of the primary tumor and of orbital metastasis appeared at about the same time. The median survival of patients with carcinoma metastatic to the orbit was 15.6 months from the time of orbital surgery. This was much better than the median survival of the 227 patients in the overall study (7.4 months) and far better than the median survival of the patients with metastasis to the anterior segment of the eye (only 5.4 months).

A comparison of the results obtained by 99m Tc-DTPA, 99m Tc-PP and 67Ga-citrate scanning in ten meningioma patients is reported. The association of conventional brain scanning, bone scanning and "tumor-positive" scanning makes it possible to identify the primary tumor, its real extent, the perifocal damage and the contiguous bone damage.

This report presents a very rare case of metastatic meningioma of the parotid gland from a recurring intracranial lesion. The primary tumor, intracranial residues, and parotid metastasis were histologically benign. Meningiomas rarely metastasize; even rarer are cases in which both the primary and the secondary tumors have benign histological characteristics. The 11 cases reported in the literature have been critically reviewed. The case we present is noteworthy also for the exceptional localization of the metastasis in the parotid gland.

A 50-year-old man, transferred from another hospital, was admitted because of adult onset seizures. Nine months earlier, he had undergone an esophagogastrectomy; the lesion was confirmed to be a carcinoid tumor. Laboratory tests, chest x-rays, and electrocardiogram were normal. A second liver and spleen scan was performed. A computed tomographic scan revealed a well-circumscribed homogeneous enhancement of a lesion in the left frontal superficial area. On the 10th day, the patient underwent a left frontal parietal craniotomy. Postoperatively, he manifested no residual neurological deficits and was discharged on the 6th postoperative day. A week later, he was readmitted for treatment of aphasia and right hemiparesis; he was treated and discharged. The patient survived 16 more months. The occurrence of central nervous system metastasis from carcinoid tumor is rare. This tumor resembled, in many respects, a parasagittal meningioma. Radiological findings on the computed tomographic scan were typical of these tumors. This patient was diagnosed as having metastatic disease just 9 months after the diagnosis of the primary tumor and 13 months from the onset of any symptoms. This is a short period of time compared with that reported in other cases.

A case of rare extracranial metastasis from a recurrent intracranial meningioma is described. Incidentally discovered asymptomatic pulmonary metastases were diagnosed as meningioma by transthoracic fine needle aspiration (FNA) biopsy. The aspirate contained spindle-shaped tumor cells and other forms that seemed to correspond to the fibroblastic, syncytial and angioblastic areas seen in the histologic sections of the primary tumor. Cytomorphologically, metastatic meningioma appears to be sufficiently distinctive to permit its cytologic differentiation from other spindle-cell tumors. Although meningiomas metastasize rarely, this diagnosis should be considered in the interpretation of a transthoracic FNA biopsy of a pulmonary nodule or nodules in a patient with a history of recurrent intracranial meningioma, especially when the aspirate mainly consists of spindle-shaped neoplastic cells.

A 68-year-old male was hospitalized because of headache, nausea, and disturbance of consciousness. Neurological examination on admission disclosed somnolence, disorientation, marked neck stiffness, papilledema, and quadriparesis. Computed tomography (CT) scanning demonstrated a round mass with marked contrast enhancement in the right sylvian fissure and small contrast-enhanced masses in the interpeduncular, quadrigeminal and ambient cisterns. CT also showed marked peritumoral edema, a midline shift, and hydrocephalus. The patient's consciousness level and respiration deteriorated 3 days after admission and a craniotomy was performed. The tumor, which was well demarcated, firmly attached to the sphenoidal ridge, and grossly appeared to be a meningioma, was totally removed. Histologically, the tumor had two well defined components, glioblastoma and fibrosarcoma. The patient underwent ventriculoperitoneal shunting, chemotherapy, and radiotherapy after surgery, but the primary tumor soon recurred, with scalp metastasis, and he died 5 months postoperatively. Autopsy revealed metastases to the liver, spleen, and spinal cord. The histogenesis of this mixed tumor and the mechanism of extracranial metastasis are discussed, and the literature is reviewed.

Three cases of intracranial perineural metastasis from adenoid cystic carcinoma of the head and neck are presented. The metastases presented more than 1 year (14 months to 5.5 years) after the primary tumor had been successfully treated without any evidence of local recurrence. Computed tomography of the intracranial metastasis demonstrated well-demarcated, hyperdense, enhancing extraaxial masses indistinguishable from meningioma. An intracranial extraaxial mass lesion with the appearance of a meningioma in a patient with known adenoid cystic carcinoma of the head and neck, regardless of the presence or absence of local recurrence, should be considered as metastasis until proved otherwise.

The authors report the case of a patient harbouring a parietal convexity tumor whose clinical and CT features were suggestive of a meningioma. Unexpectedly the tumor was a well differentiated adenocarcinoma from a colon cancer with a markedly PAS positive intragland content represented by wide areas of mucoid degeneration. Brain metastases from colon cancer are usually late occurrences and it is extremely rare that the brain lesion be discovered while the primary tumor is still unknown. The authors discuss about the pathogenesis of the CT appearance of adenocarcinoma which is, usually, slightly hyperdense. On the basis of the reported findings it is suggested that mucoid degeneration may induce the development of a well defined CT pattern represented by a very high density appearance with no contrast enhancement.

A very unusual case of metastatic spread of a meningioma is described. The clinical presentation was of extradural spinal cord compression, without evidence of a primary tumor. Computed tomography did not reveal any intracranial meningioma; the histopathology of the extradural spinal tumor was identical with that of two intracranial meningiomas previously excised.

We report a patient with renal cell carcinoma metastatic to the left trigone, which mimicked an intraventricular meningioma. The metastasis was recognized 1.3 years after removal of the primary tumor, a longer disease-free interval than any previously reported cases with brain metastases of renal cell carcinoma. The patient is now free of disease of years after resection and 17 years after the discovery of the primary tumor. Metastatic disease should be considered in all patients with prior resection of renal cell carcinoma who experience the onset of neurological disease, even after a prolonged disease-free interval. Long term survival is observed after the resection of solitary metastases, particularly if these appear after a prolonged disease-free interval.
