Brachial plexus root avulsion: role of myelography--review of diagnostic procedures.

Myelographic evidence of traumatic meningocele in brachial plexus injuries has been considered to be pathognomonic of root avulsion. Two such cases with myelographic evidence of root avulsion with excellent recovery at those levels are presented. Various diagnostic procedures in brachial plexus injuries are critically reviewed. The sequence in which these tests are of diagnostic value are: 1) clinical evaluation, motor and sensory, from the time of admission; 2) electroneuromyography at 2-3 weeks following injury; 3) axon reflex response at 2-3 weeks; 4) myelography; 5) very rarely, surgical exploration.

Spinal dysraphism associated with congenital heart disorder in a girl with MELAS syndrome and point mutation at mitochondrial DNA nucleotide 3271.

We describe a case of mitochondrial encephalopathy, lactacidosis, and stroke-like episode (MELAS syndrome) associated with ventricular septal defect and meningocele at the L3 level in a 5-year-old girl. Mitochondrial DNA analysis showed point mutation at nucleotide 3271--> TC. The occurrence of heart and neural tube defects in association with usual features of the MELAS syndrome might be explained by either defective high-energy metabolism during early embryogenesis or a common genetic cause.

[Sacrum abnormalities and neural tube closure defect: different manifestations of a same genetic disease?].

The authors report the case of a full-term female infant exhibiting an anterior meningocele, combined with a hemi-sacrum and an anal dysfunction. Both her father and brother had the same although less pronounced abnormalities. The father's sister was anencephalic. This case, together with previously published data, suggests that sacrum malformations and neural tube defects may derive from a unique dominant autosomal gene with variable expressivity.

[Apparently primary cerebrospinal rhinorrhea. Apropos of 4 cases].

While rhino-liquorrhea is a severe condition, its incidence is not exceptionally rare, and it raises problems, namely etiopathogenic, diagnostic and therapeutical ones, which call for the close collaboration of ENT doctors, neuroradiologists and neurosurgeons. 4 relatively recent cases are reported here, whereby the diversity of the problems encountered is made apparent. ENT specialists must be aware of those when faced with refractory aqueous rhinorrhea, often triggered by forward head motion, Valsalva's maneuver... Screening for rhinorrhea is readily achieved by biochemical tests, or simply using a Labstix-type diagnostic strip. Rhinoscopic examination should be accurate and carried out optically to check for any congenital malformation (meningocele). Most of the times, but not always, a thorough radio-neurological workup (isotopic analysis, CT-scan with contrast medium, MR imaging) will provide precise data regarding the infraction site and its possible cause, invariably warranting surgical management. Surgery should be case-adapted (CSF derivation, filling of the gap via the extra- or intracranial approach).

[A case of intrathoracic perineurial cyst].

A 67-year-old man was referred to our surgical clinic for evaluation of an abnormal shadow on the chest X-ray examination. CT scan and MRI revealed a tumor in the posterior mediastinum and destruction of the pedicle and intraspinal invagination by the tumor. The tumor in a paravertebral area are linked with a vertebral canal through a destructed intervertebral foramen. MRI showed that the tumor was a cyst which contained fluid. On thoracotomy a hen's egg sized cyst was found in the posterior mediastinum, the cyst was excised. Pathological diagnosis was a perineurial cyst. This case was clearly differentiated from an intrathoracic meningocele and a neurilemmoma microscopically. This case is the first intrathoracic perineurial cyst in Japan.

[Pseudomeningocele after laminectomy].

Pseudo-meningocele post-laminectomy is a non-frequent complication of this surgical technique. It is usually diagnosed by myelography; the CT scan has helped to detect more cases. We present a case studied by CT and RMN and there are no existing previous publications on the case confirmed by RMN. The relation between the findings and the clinic as well as the therapy still on discussion.

[Clinico-electromyographic studies in congenital spinal hernia].

As many as 33 children operated on for congenital meningocele of the inferior parts of the spine were subjected to clinicoelectromyographic studies. Alterations seen in the amplitude of the maximum M-response serve as one of the objective indicators of the degree of neuromuscular lesions. According to the magnitude of that amplitude, the patients were distributed into 4 groups: I /0 mV/, group II /0-1 mV/, group III /1-6 mV/, group IV /more than 6 mV/. The F wave reflecting the status of antidromic excitability of the spinal motoneurons is only recordable in groups III and IV of the patients (65%), with the magnitude of the maximum M-response being over I mV. H-reflex, as an indicator of reflex excitability of the motoneurons, is the most labile electromyographic parameter which is only recordable in some patients belonging to group IV, constituting 12% of the total number of the examined patients.

Multiple frontobasal meningoencephaloceles in neurofibromatosis.

A patient is reported who has multiple osseomeningeal defects and bilateral frontobasal encephaloceles in the context of a neurofibromatosis. After frontobasal revision with plastic closure of a cerebrospinal fluid fistula, the rhinoliquorrhea cleared, but there was an aggravation of a preexisting internal hydrocephalus with signs of raised intracranial pressure. The conditions were stabilized after various shunt operations. Additional diagnoses included a cyst (possibly a colloid cyst) in the anterior third ventricle and partial aplasia of the anterior trabecula. The particular problems in this case in relation to the spinal meningoceles already known in neurofibromatosis and spheno-orbital encephaloceles are discussed.

Dural penetration by interspinous process segmental spine instrumentation: case report.

A case of pseudo-meningocele complicating posterior spine fusion with interspinous process segmental spinal instrumentation is presented. The L rod rotated postoperatively 90 degrees and penetrated the dura. The presenting symptoms were pain accompanied by fixed lumbar and hip flexion contractures that improved dramatically after removal of the penetrating part. The unusual course as well as the treatment and recommendation for prevention are discussed.

Comparative teratogenicity of triamcinolone acetonide and dexamethasone in the rhesus monkey (Macaca mulatta).

Pregnant rhesus macaques were treated with 0.5 or 2.5 mg/kg triamcinolone acetonide (TAC) or 1.0 or 10.0 mg/kg dexamethasone sodium phosphate (DEX) between 20 and 50 gestational days (GD). Treatment with TAC at 2.5 mg/kg resulted in a fetal loss of 71%; 3/5 recovered fetuses displayed an encephalocele or meningocele. All other treatment groups displayed minor cranial skeletal abnormalities consistent with glucocorticoid-mediated teratogenesis. DEX was shown to have a lower teratogenic potential than TAC in this species.

[Roentgen signs of rare mediastinal masses (author's transl)].

Mediastinal masses are commonly classified into lesions of the anterior, middle, and posterior compartment as a first step in differential diagnosis. Teratoma, neurogenic tumors, goiters, and thymoma with their characteristic localization constitute together already two thirds of all mediastinal neoplasms. However, the differential diagnosis of mediastinal masses should include also rare diseases: lymphangio-hemangioma, aneurysm of the pulmonal artery, intrathoracic meningocele, esophageal cyst, and pleurobronchial cyst are demonstrated. It is emphasized, that differential diagnosis has to consider history and physical data of the patient as well.

[Computed tomographic diagnosis of pre- and paravertebral masses in the thorax and retroperitoneum].

CT is the method of choice in the diagnostic identification and clarification of prevertebral and paravertebral space-occupying growths before initiating invasive methods of diagnosis and before surgery. CT supplies decisive information by means of the transversal tomography, which is free from overlapping, and enables determination of relative densities. A most important feature is the safe exclusion of any aortoilacal aneurysm via differential diagnosis. The possibilities and limitations of computed tomography are discussed on the basis of several examples, namely, a lateral intrathoracic meningocele, a mediastinal bronchogenic cyst, a retroperitoneal fibrosis, lymph node metastases and hypostatic abscesses.

Congenital rectal stenosis: a sign of a presacral pathologic condition.

Congenital rectal stenosis may be detected in the newborn during the initial physical examination. Failure of conservative therapy (dilatation) should alert the physician to the presence of an associated pathologic condition in the presacral space. Presacral teratoma, anterior sacral meningocele, or bony anomalies may be the underlying extrinsic causes of congenital rectal stenosis. Prompt recognition and appropriate operative management directed at the presacral lesion will relieve obstructive symptoms and minimize morbidity.
