A rare case of mesenchymal chondrosarcoma originating from the thoracic spinal dura was reported. A 10-year-old girl complained of paresis of the right leg in June 1977. Then she became unable to walk early in August, and a complete paraparesis developed on August 18. She was admitted to our department on August 22. On admission she had complete paraparesis, bilateral ankle clonus, upward plantar reflexes, sensory disturbance below T7, shincter disturbance and neck stiffness. Plain thoracic X-ray revealed bilateral decalcification of pedicles of T6. Myodil myelography showed a complete block between T6 and lower end of T7 vertebrae. Bilateral laminectomy from T3 to T8 was performed. A tumor originating from the spinal dura was located in the right dorsal extradural space. The tumor was totally removed together with a small area of the affected dura. Light microscopy showed mesenchymal chondrosarcoma. Her recovery from neurological deficiencies was excellent and now she can run 14 months after surgery. Metastasis or recurrence has not yet been seen.

Eight patients treated for histologically confirmed primary spinal epidural non-Hodgkin's lymphoma diagnosed between January 1979 and August 1989 (6.6% of all cases of intraspinal lymphoma) were studied. There were six men and two women. The median age was 70 years (range, 43-80 yr). Patients sought treatment for a prodrome of back pain (median duration, 3 mo) followed by an acute neurological deterioration (median duration, 6 d). The most common findings were a discrete sensory level in 5 patients, hyperreflexia in 5 patients, and paraparesis or paraplegia in 5 patients. Radiographically, there was an absence of bony destruction by these tumors. All patients underwent a decompressive laminectomy, subtotal tumor resection, and spinal irradiation (median dose, 3800 cGy). Two patients had low-grade lymphomas (one B cell and one T cell), and 6 patients had intermediate-grade lesions (six B cell). Two patients with B-cell lymphomas (one low-grade and one intermediate-grade) developed metastatic disease 15 and 17 months after the initial diagnosis; no evidence of lymphoma developed in the other 6 patients. The median survival was 22 months (range, 2-71 mo). Lymphoma was the cause of death in only 1 of the 4 patients who died, and the 4 younger patients are alive and well. Primary spinal epidural non-Hodgkin's lymphoma should be a diagnostic consideration in the older patient who seeks treatment for spinal cord compression manifested by a prodrome of back pain, followed by a rapid neurological deterioration, normal plain spine radiographs, and neuroimaging consistent with an extradural compressive lesion. Surgery for this diagnosis followed by spinal irradiation should result in significant neurological improvement.

We have studied an unusual, spontaneous, intradural extramedullary spinal cord tumor in 12 dogs. Animals presented with paraparesis and ataxia early in life (11/12 ranged from 6 to 38 months of age) suggesting that these tumors may be congenital. Various breeds of dogs were represented with four cases in German Shepherds and three in retrievers; there was no sex predisposition. Post-mortem examinations revealed a single intradural mass consistently located between T10 and L2, which produced extensive compression of the spinal cord. Metastasis was never observed and significant pathological changes in other organs were lacking. Microscopic examination revealed solid sheets of ovoid to fusiform cells interspersed with areas of acinar and tubular differentiation. Some areas were rarified and focal squamous metaplasia was observed. Ultrastructural features included the presence of a continuous basal lamina, junctional complexes, microvilli and occasional cilia at the apices of acinar complexes. Immunocytochemical studies did not support a neurectodermal origin. At least 13 case reports of this entity have been previously published and have been designated ependymomas, medulloepitheliomas and neuroepitheliomas. A recent case was diagnosed as a nephroblastoma and we feel that this is an interesting and provocative diagnosis. These tumors could result from remnants of renal primordium which becomes trapped between the dura and the developing spinal cord. However, firm evidence of such a histogenesis is not yet at hand.

A 42-yr-old woman had a solitary metastases to her spine (T2) from a malignant struma ovarii. The thyroid was excluded as the site of the primary cancer. The lesion caused paraparesis. The spinal metastasis was treated by surgery and two doses of 131I (200 mCi each time). The patient responded very well and is entirely free of symptoms and signs. Repeat whole-body 131I scan shows no abnormality.

We report the history, laboratory and histological findings in a man who presented with Cushing's disease. Despite removal of the primary pituitary tumour, his disease progressed and after bilateral adrenalectomy, he became pigmented and plasma ACTH levels remained elevated. He had further pituitary surgery and radiotherapy, to relieve compression of the optic chiasma. Plasma ACTH levels remained elevated. He developed liver, bone and lymph gland metastases and after an acute paraparesis due to spinal metastases he died. Immunoperoxidase staining techniques demonstrated ACTH in the pituitary recurrence and metastases. The combination of bone, liver and lymph node metastases has not previously been reported, nor has ACTH been reported before in metastases from a primary intrasellar tumour.

A clinical description and pathological findings are reported in a case of extrameningeal, angiogenic malignant meningioma of the vertebral canal (Th7-Th11) in a patient aged 17 years. Clinical picture was that of transverse myelitis at the Th9 level, with spastic paraparesis, funicular loss of all sensory functions and sphincter disturbances. The authors suppose that the used combined treatment (chemotherapy and radiotherapy, surgery) improved greatly the health state inhibiting the spread of metastases and prolonged survival to 3 years. Autopsy demonstrated recurrence of he tumour in the vertebral canal and numerous metastases to the brain, lungs, liver, bones and pancreas.

Since 1924, when ependymomas were first classified as a distinctive glial neoplasm by Bailey, much has been published concerning these tumors, but there are important points of interest that are still not clear. In order to study more fully the clinical and pathologic characteristics of the ependymoma, we identified 62 patients with histologically proven neoplasms. Twenty-two were supratentorial, 21 were infratentorial, and 19 were intramedullary spinal cord tumors. These groups had mean ages of 17, 7, and 41 years, respectively, at the time of first symptoms. The presenting and accompanying symptoms were related to location and included headaches, nausea, visual changes, hemiparesis, and neck, back, and radicular pain. Neurological signs included papilledema, nystagmus, gait disturbance, cranial nerve palsies, altered mental status, paraparesis, and sensory dysfunction. Radiologic modalities of particular importance included computed tomography and myelography. Surgery and radiation therapy were the primary treatment modalities with median survival times from first symptoms being 92, 36, and 117 months for the above groups, respectively. Based on computer-generated survival curves, several characteristics significantly affected survival. These included tumor site, age, and neuraxis metastases. In patients with supratentorial tumors, cranial nerve palsies, microcystic changes, and mitotic figures were important, while in patients with infratentorial tumors, widened sutures, increased head circumference, age, epithelial features, and subependymal features significantly affected survival. Patients who had complete gross resection of a spinal cord tumor had no recurrences or mortality.

Fifty-seven patients with spinal metastases underwent 60 operations. 36 patients were operated on by anterior approach with decompressive coporectomy and stabilization by metal and methylmetacrylate and 24 patients by laminectomy and/or stabilization by osteosynthesis. Postoperative improvement of the pain syndrome was observed after 56 operations. Neurologic signs were present in 23 patients with paraplegia (5 patients) or paraparesis (18 patients); 15 of the latter patients improved and recovered walking capacity. Two types of metastasis were distinguished: corporal metastasis, in which vertebral wedging and posterior protrusion led to neural deficit, with a good prognosis if treated by anterior surgery, and pericordal metastasis in which the cord compression is due to metastatic proliferation into the spinal canal. Results after decompressive surgery, either by posterior or anterior approaches are more doubtful. Surgery is beneficial and should be preferred to radiation when there is medullary compression by corporal metastasis and also in the presence of intense pain or potential instability of the spine.

Myelography was performed on 78 patients with breast cancer who had signs or symptoms compatible with spinal cord compression. Of 42 patients (54%) with extradural defects, 21 (50%) had a complete block. All patients with positive myelograms (M+) had a positive bone scan and 41 of 42 (97%) had positive skeletal x-rays. Except for paraplegia, paraparesis, or a sensory level abnormality, signs and symptoms were usually not precise enough to accurately predict patients with cord lesions; however, back pain, paresthesias, and bladder or bowel dysfunction were significantly more common in M+ patients. Cerebrospinal fluid (CSF) protein was elevated in almost all M+ patients but also in approximately half of the M- group. Cytology and glucose analysis of CSF were not of value in predicting cord involvement. Response to treatment was better for patients with fewer sites of metastatic disease and a shorter time from diagnosis to treatment. There was no notable difference in survival between M+ and M- patients. Myelography remains the most precise tool for diagnosing spinal cord lesions. Unfortunately, the prognosis of patients with metastatic breast cancer is poor regardless of whether spinal cord compression is present.

Myeloma may be complicated or revealed by spinal cord compression. Out of 105 cases of myeloma admitted to this Department, 6 cases of spinal cord compression were observed, with a favourable outcome after treatment by laminectomy combined with radiotherapy. In 5 cases out of 6, spinal cord compression was either the presenting sign or occurred within the first months after diagnosis. Compression occurred in the thoracic cord in 5 cases, and in the lumbar cord in 1 case. The interval between the first symptom and diagnosis varied greatly (from a few hours to 1 year), as did the degree of paraplegia, which ranged from paraparesis to flaccid paraplegia. A favourable outcome occurs in most other reported cases, in contrast with spinal cord compression from metastases. Treatment (laminectomy-radiotherapy or both) remains controversial.
