A case of
metastases
to the spinal subarachnoidal space from a primary anaplastic pulmonary tumor visualized by
Amipaque
myelography is reported.

The clinical data and imaging studies of 12 patients with intramedullary
metastases
were reviewed retrospectively to see if these lesions had a typical radiographic appearance and to determine the sensitivity of the various radiologic examinations. The lesions were identified antemortem by either myelography, CT, MR, and/or intraoperative spinal sonography (IOSS). Final diagnosis was based on biopsy material from either the spinal cord lesion, another metastatic site, and/or the primary tumor. Ten patients had primary tumors located outside the central nervous system, while only two patients had primary brain tumors.
Metrizamide
myelography and CT demonstrated a definite intramedullary mass in nine of 11 patients. In five patients the mass was relatively small, well-defined, single, and resembled a primary spinal cord neoplasm. In the other four patients, longer and sometimes several segments of the cord were involved. These appeared irregular and nodular and were often associated with intradural lesions at separate sites. MR detected not only enlargement and abnormal signal in the cord but also clinically unsuspected brain lesions. IOSS localized lesions for biopsy and monitored tumor resection. These various imaging procedures showed that cord
metastases
were often more extensive than anticipated clinically. Spread of tumor into the spinal and intracranial subarachnoid space was common. Imaging of the entire spinal canal and brain, preferably with MR, is therefore recommended to aid in diagnosis, prognosis, and treatment.

During a 6 month period, 50 patients with signs and symptoms referable to the cervical spine were studied with a 0.6 T superconducting magnetic resonance (MR) imaging unit. The last 23 of these 50 patients were studied with combined multislice and multiecho techniques. In 38 of the 50 patients, abnormalities were demonstrated on MR images. Intramedullary lesions included syringomyelia (three cases), primary tumors (two), metastatic neoplasm (one), cord atrophy secondary to trauma (one), and multiple sclerosis (one). Intradural, extramedullary lesions included two neurofibromas and two Chiari malformations. The rest of the lesions were extradural: degenerative changes (10), spinal stenosis with cord compression (five), disk degeneration and/or herniation (five), postoperative changes (four),
metastases
to bone/epidural disease (three), and neurofibromatosis (one). Two patients had more than one abnormality. The MR findings were compared with available routine radiographs, computed tomographic (CT) scans with and without metrizamide, and myelograms. MR imaging was consistently better than routine CT scanning in the detection of lesions of the spinal cord and in directly imaging the effects on the spinal cord of extrinsic abnormalities such as spinal stenosis.

-enhanced CT scanning detected all cases of syringomyelia, but it involved an invasive procedure. Myelography alone was slightly less sensitive and considerably less specific than MR in detecting intramedullary lesions and in distinguishing cord neoplasms from syringomyelia. Multislice, multiecho techniques with up to 240 msec echo times (TEs) were particularly helpful in the detection and characterization of extradural processes.(ABSTRACT TRUNCATED AT 250 WORDS)

Five cases of neonatal thoracic neuroblastoma were either clinically asymptomatic or presented as uncharacteristic respiratory distress. Chest radiography demonstrated a spectrum of abnormalities varying from a lobulated, apical thoracic mass with or without evidence of expansion, to a spindle-shaped paraspinal soft tissue widening, or a homogeneously dense hemithorax. In the newborn a neoplasm in the posterior mediastinum most likely represents a neuroblastoma, either primary or metastatic. In a high percentage of cases the primary tumour as well as possible skeletal
metastases
have an increased uptake of radiopharmaceuticals. Therefore a bone scan should be the next step for evaluation of the neoplasm. Supplementary sonographic screening of the retroperitoneum and lesser pelvis is easily performed and may contribute significant information. Urography is hardly mandatory any longer.

CT myelography, highly recommended in infants and children, may be omitted in the neonate with no neurologic deficit. Urinary excretion of catecholamine metabolites is usually elevated and must always be determined.

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.

Twenty-six patients with medulloblastoma had complete myelography and spinal fluid cytology and tests for polyamine levels in the evaluation for spinal
metastases
. The nature and location of abnormalities are presented in this report.
Metrizamide
was demonstrated to be safe and effective for complete myelography in children. The usefulness of myelography in detecting spinal
metastases
at the time of initial diagnosis (11%) and at the time of first intracranial recurrence (33%) is discussed.
