摘要:

&NA;We report the cases of two patients, each of whom had two separate angiographically demonstrable intracerebral arteriovenous malformations (AVMs). One patient had an intraventricular hemorrhage with AVMs in the basal ganglia and the insula on the left side, and the other had a pontine hemorrhage with AVMs in the pons and the occipital lobe on the right side. The AVMs in the former patient were removed totally without residual neurological deficit. We discuss the diagnostic problems of multiple intracerebral AVMs and stress the need for thorough neuroradiological evaluation so as not to miss an occult AVM. We also stress the necessity of total excision of all the lesions and point out several problems faced in surgery for AVMs. (Neurosurgery25:281‐286, 1989)

摘要:

&NA;Two patients with altered hemostatic mechanisms developed spinal subarachnoid hemorrhage after difficult lumbar punctures. One patient had received anticoagulation therapy soon after lumbar puncture and the other had a low platelet count (63,000/mm3) at the time of lumbar puncture. In both patients a hematoma evolved, producing blockage of cerebrospinal fluid flow. Clinical manifestations consisted of severe back and radicular pain with sphincteric disturbances followed by rapidly developing severe paraparesis. Of the methods of radiographic evaluation that were used, including computed tomography (CT) without contrast enhancement, myelography, CT with intrathecally administered contrast medium, and magnetic resonance imaging, we found the best study to be myelography via lateral cervical puncture followed by CT. Unfortunately, diagnosis was delayed, and surgical evacuation of the hematomas did not substantially improve the patients' conditions. The salient clinical and radiographic features of this disorder and its pathophysiology are reviewed. Prompt recognition of these lesions is necessary so that surgical intervention may maximize chances of recovery. (Neurosurgery25:287‐293, 1989)

摘要:

&NA;Two cases of simultaneous Jefferson fracture of C1 and Type II odontoid fracture requiring surgical stabilization are reported. One patient required early stabilization because alignment could not be maintained in a halo vest, and the second patient required late stabilization for nonunion after a 3‐month period of immobilization in a two‐poster cervical brace. Although this uncommon injury can often be managed conservatively, surgical fusion will need to be considered in the setting of early or late instability. (Neurosurgery25:293‐297, 1989)

摘要:

&NA;A case of cervical myeloradiculopathy secondary to deposits of calcium pyrophosphate dihydrate (Ca2P2O72H2O) (CPPD) crystals in the degenerating ligamentum flavum, with marked granulomatous inflammation, is presented. This uncommon clinical presentation of pseudogout (CPPD deposition disease) was confirmed after surgical removal of a compressive cervical ligamentum flavum. The diagnosis of CPPD crystal deposition was determined by polarized light microscopy and energy‐dispersive x‐ray microanalysis in frozen sections of the biopsy specimen. A review of seven previously reported cases along with the present case failed to reveal trauma as a causative factor. (Neurosurgery25:298‐302, 1989)
