The authors report a case of an ependymoma in which metastases in cervical lymph nodes appeared four and a half years after diagnosis and operation. The primary tumor, an ependymoma grade I (WHO) in the left occipital region, had been completely resected and irradiated. Beside metastases in the cervical lymph nodes, several recurrences in the primary region and multiple metastases to the spinal canal had occurred.

A subcutaneous sacrococcygeal located myxopapillary ependymoma is a rare presentation of this malignancy. It has a tendency to metastasize, even after a long latent period. This is a report of such a case together with proposals for treatment and follow-up.

Two cases of extraspinal ependymoma are described. This is a low-grade tumor that recurs locally unless wide local excision is performed. It does metastasize, mainly to lymph nodes and lung. Its origin is likely from heterotopic ependymal cells called the coccygeal medullary vestige.

Twenty patients with intracranial ependymoma (16) or anaplastic ependymoma (4) received post-operative radiation therapy at the University of California, San Francisco from 1959 through 1981. No patient received prophylactic spinal irradiation. The actuarial survival at 5, 10, and 15 years for 15 patients with ependymoma who received greater than 45 Gy was 67, 57, and 46%, respectively. Only one patient (7%) developed clinically recognized spinal metastases; this patient was eventually shown to have tumor at the primary site, within the irradiated volume. Six of 11 patients treated with partial brain irradiation had an intracranial recurrence, versus 1 of 4 patients treated with whole brain irradiation. Three patients were autopsied after failing partial brain irradiation for an ependymoma and the site of failure was within the irradiated volume of each patient. Partial brain irradiation was used to treat 4 patients with anaplastic ependymoma. One developed a local recurrence within the irradiated volume. The other three survived longer than 10 years. At UCSF, most patients with low grade ependymomas are presently treated with partial brain irradiation, but whole brain plus spinal irradiation is used for anaplastic tumors.

A common cause of malfunctioning ventricular shunts is the occlusion of either tip by a variety of normal or reactive tissues and foreign substances. A six-year-old girl with communicating hydrocephalus and a meningomyelocele, a 48-year-old man with an ependymoma and an 11-year-old boy with a pineal germinoma had multinucleated histiocytic giant cells and ependymal cells in cerebrospinal fluid obtained from their ventricular shunts. These cellular changes were interpreted as the cytologic counterpart of the foreign-body inflammatory reactions often seen histologically on occluded shunt tips. Numerous clusters of benign choroid plexus epithelium were found in an ascitic fluid from a six-year-old girl with an optic nerve glioma and a ventriculoperitoneal shunt. Such embolism of normal tissues must be distinguished from metastases from intracranial neoplasms.

Extraneural metastasis of intracranial ependymoma is a rare pathological entity. Thirty one case reports were traced in the review of the literature and we record one of them. The patient was a 19-year-old male in good health until January 1981 when he was admitted to our hospital with deteriorating mental status. Admission work-up revealed bilateral papilledema, 1-hemiparesis and increased intracranial pressure signs including vomiting. CT scan demonstrated significant abnormality of enhanced mass lesion in the r-temporo-parietal area in which a displacement of the midline structure to the left occurred. R-temporo-parietal craniotomy was performed on the admission day. The globular tumor mass occupied the temporo-parietal area and invaded the cortex. Subtotal resection of the tumor and temporal lobectomy was performed. Microscopic examination of the operative specimen revealed a typical ependymoma pattern. For the next two years, he received operations twice, irradiation (total 14, 170 rads) and various chemotherapy. Two months after the fourth craniectomy, examination revealed scalp overlying the burr opening to be very tense and enlarging as if invaded by the tumor. A large mass occupied the right lateral cervical area and chest X-ray disclosed complete opacity on the right. He gradually developed severe cough and sputum and died two months later on January 1, 1984. At autopsy, the result was that tumor had invaded the subarachnoidal space and subcutaneous area. Extraneural metastases were found to be bronchial lymph nodes, C-4 vertebra, r-cervical lymph node. The histological appearance of these tumors obtained at autopsy was identical to the cerebral tumor.(ABSTRACT TRUNCATED AT 250 WORDS)

Cerebrospinal fluid (CSF) polyamine levels were analyzed retrospectively in 21 pediatric patients with different types of intracranial malignant tumors to determine the benefit of following these markers during the clinical management of brain tumors. The tumors included 16 medulloblastomas and 1 each of germinoma, ependymoma, primitive neuroectodermal tumor, astrocytoma, and malignant teratoma. The clinical course of each patient was followed by neurologic examination, cranial computed tomography, CSF cell count, and cytology after cytocentrifugation. The correlation of CSF putrescine and spermidine levels with the clinical course of the brain tumors was analyzed. The following results were obtained: (1) A significant increase in CSF putrescine levels was observed in children with medulloblastoma when there was recurrent or metastatic disease in the sites close to the CSF pathway compared with the children whose disease status was stable after successful treatment (P less than 0.005). (2) The increase of CSF putrescine levels was the earliest predictor of recurrence or metastasis near the CSF pathway. (3) In tumors other than medulloblastoma, the levels of polyamines were not predictive of disease activity with the possible exception of germinoma. (4) Spermidine levels in the CSF were of limited clinical importance for patients with brain tumors. CSF putrescine levels may be the earliest and most sensitive quantitative marker of the progression of medulloblastoma, and their evaluation should be included in the diagnostic work-up and follow-up examination of children with medulloblastoma.

Ependymomas of the sacrococcygeal region almost always arise on the posterior aspect of the sacrum in the soft tissues and subcutaneous tissues of this region. The predominant histologic type of ependymoma in the sacrococcygeal area is myxopapillary. We report a case of myxopapillary ependymoma arising in the presacral area and presenting clinically as an abdominal mass. Ependymomas arising on the ventral aspect of the sacrum are exceedingly rare, and only 24 previous cases have been reported in the English literature. While dorsal myxopapillary ependymomas occasionally metastasize, there have been no reports of metastasis in the presacral tumors of this type.

It is reported on three patients which suffered from severe side effects after cervical myelography using Amipaque (cases 1 and 3) and Pantopaque (case 2). In 2 cases death occurred after 13 days (case 2) respectively 17 days (case 3). Worsening of the clinical symptoms appeared in all cases within four days after myelography. In the first 2 cases inflammatory alterations prevailed whereas in the third case complications probably based on mechanical irritations of nerval and vascular structures. In the 2 lethal cases autopsy offered a prostatic cancer with vertebral and intraspinal metastases respectively syringobulbia and cervical syringomyelia beside an ependymoma of the cervical spinal cord as incurrable complaints. The various side effects and complications after myelography using positive contrast media as well as their causes are discussed.

A case of a widely metastasing malignant ependymoma in a 35-year-old man is reported. The first and most impressive clinical feature was a massive subarachnoid bleed with rapidly developing spinal cord compression due to widespread metastases over the cord and the cauda equina. The cerebral ependymoma was finally shown on a CT scan. Subarachnoid haemorrhage caused by malignant spinal deposits seems to be exceedingly rare. Finally, some problems of classification concerning the malignant forms of ependymoma are discussed.
