Nerve root compression by a gas-containing cyst associated with stenotic lateral recess. Case report and review of the literature.

The authors describe a case in which a gas-containing cyst was associated with a stenotic lateral recess at the same level in the absence of any disc material. A young man presented a one-month history of sciatica caused by compression of the left L5 nerve root. The neuroradiological investigations performed (CT, MRI) showed the presence of a gas-containing cyst associated with a stenotic lateral recess. The clinical, etiopathological characteristics and treatment of this condition are discussed and the pertinent literature is reviewed. Decompression of the nerve root was obtained by surgery. The herniated gas collected within a capsule (gas-containing cyst) can act as a mass and produce symptoms, much like a herniated nucleus pulposus. The antalgic stance adopted by the patient with marked flexion of the spine helps to distribute the pressure exerted by the cyst over a wider area (Pascal's law I). The appropriate procedure to relieve the radicular compression caused by gas-containing cyst seemed to be the surgical treatment.

Choroid plexus metastasis from carcinoma of the bladder: case report and review of the literature.

We present here a case report of a 40-year old male with adenocarcinoma of the bladder and solitary metastasis to the choroid plexus of the right lateral ventricle. This is the first such report of such a metastasis in association with bladder carcinoma. Systemic metastases frequently occur in patients with carcinoma of the bladder but involvement of central nervous system is relatively uncommon: less than 1% of patients with carcinoma of the bladder present an intracerebral metastasis. In the majority of cases there are either multiple CNS metastases or other distant metastases. A few cases present with solitary metastases to the CNS without evidence of recurrent or disseminated disease.

Abducens nerve paresis as first symptom of trigeminal neurinoma. Report of two cases and review of the literature.

Two cases of neurinoma of the Gasserian ganglion with abducens nerve paresis as the first symptom are described and 27 cases culled from the literature are reviewed. The anatomo-surgical and clinical-radiological features of this pathology were re-assessed in an attempt to identify the pathogenetic mechanism responsible for a trigeminal neurinoma manifesting with VI cranial nerve palsy.

Surgical treatment of penetrating orbito-cranial injuries. Case report.

Penetrating orbital injuries are not frequent but neither are they rare. The various diagnostic and therapeutic problems are related to the nature of the penetrating object, its velocity, shape and size as well as the possibility that it may be partially or wholly retained within the orbit. The authors present another case with unusual characteristics and discuss the strategies available for the best possible treatment of this traumatic pathology in the light of the published data. The patient in this case was a young man involved in a road accident who presented orbito-cerebral penetration caused by a metal rod with a protective plastic cap. Following the accident, the plastic cap (2.5x2 cm) was partially retained in the orbit. At initial clinical examination, damage appeared to be exclusively ophthalmological. Subsequent CT scan demonstrated the degree of intracerebral involvement. The damaged cerebral tissue was removed together with bone fragments via a bifrontal craniotomy, the foreign body was extracted and the dura repaired. Postoperative recovery was normal and there were no neuro-ophthalmological deficits at long-term clinical assessment. Orbito-cranial penetration, which is generally associated with violent injuries caused by high-velocity missiles, may not be suspected in traumas produced by low-velocity objects. Diagnostic orientation largely depends on precise knowledge of the traumatic event and the object responsible. When penetration is suspected and/or the object responsible is inadequately identified, a CT scan is indicated. The type of procedure to adopt for extraction, depends on the size and nature of the retained object. Although the possibility of non-surgical extraction has been described, surgical removal is the safest form of treatment in cases with extensive laceration and brain contusion.

Ectopic dural osteolytic meningiomas.

Intracranial meningiomas usually originate from the arachnoidal cells of the internal dural layer: meningiomas that originate from different sites are ectopic. The authors describe the case of a small meningioma adhering to the external dural layer without involvement of the internal layer, accompanied by osteolysis of the internal surface of the skull. A review of the literature on cranial ectopic meningiomas yielded only four cases described as originating from the external dural layer. Osteolysis of the skull was always present and was not found to have prognostic significance. The authors suggest that these four primary ectopic meningiomas originating from the external dural layer should be differentiated from intraosseous meningiomas of the skull.

Cystic meningioma: neuroradiological (MRI, CT) and macroscopic intraoperative appearance. A case report.

Differential diagnosis of intracranial cystic meningiomas may present difficulties in about 10-15% of cases where anatomo-pathological alterations such as intratumoral necrosis, cystic cavity, hemorrhage or lipomatous infiltration are present. These alterations are responsible for an unusual radiological appearance which may suggest a false diagnosis. We describe a case of meningioma with a cystic appearance in which MRI was more helpful than CT, because it suggested an extra-axial meningiomatous lesion and thus allowed more precise surgical planning.

Peduncular hallucinosis following a transoral odontoidectomy for cranio-vertebral junction malformation. A case report.

This is a case report of a sixty-two years old man suffering from a cranio-vertebral malformation whose dens epistrophei was removed through a transoral approach. During the postoperative course, he experienced a transient peduncular hallucinosis probably caused by surgical trauma on his brainstem. The possible physiopathological, etiopathological, clinical, and therapeutic aspects of this rare phenomenon are discussed.

Epidural lipomatosis with lumbar radiculopathy in one obese patient. Case report and review of the literature.

Idiopathic epidural spinal lipomas are rare: only 13 cases have been described in the literature. We report a further case in an obese patient without known etiological factors. Diagnosis of epidural lipomatosis was performed by MRI. Weight reduction was obtained by conservative treatment, reserving surgery in case symptoms did not disappear. Of the 8 obese patients with idiopathic epidural spinal lipomatosis described in the literature, 3 were treated conservatively, with complete regression of symptoms in 2 cases, partial in the other one. In our patient, the radicular symptomatology disappeared once he had lost weight.

MRI in the diagnosis of cystic meningiomas: surgical implications.

Nine cases of cystic meningioma diagnosed by MRI are described. All cases were surgically confirmed. The lesion was extra-axial with a clear dural attachment. On T1-weighted images the solid component was iso-hypo-intense in 6 cases and iso-hyperintense in 3; on T2-weighted images it was hyperintense in 7 cases, iso-intense in 2. After i.v. injection of gadolinium, the solid component enhanced in all cases and a "dural tail" were visible in 8 cases. No gadolinium enhancement of the cyst wall was observed in Nauta's types II and III. The authors found MRI to be very useful for diagnosis of cystic meningioma but insufficient for differential diagnosis between types II and III according to Nauta. This aspect requires further study, especially in view of the implications of this differentiation in terms of surgical management.

Clinical and radiographic stabilization of intracranial glioblastoma. Report of a case treated after surgery with tamoxifen.

We report the case of a patient with a left temporal-parietal glioblastoma treated with subtotal surgical excision, radiotherapy and chemotherapy, with a single intravenous administration of carboplatin and continuous oral administration of tamoxifen (40 mg/daily). Two years after the patient presents a stabilization of clinical and CT picture. We discute the possible role of tamoxifen in prolonging the survival of selected patients with intracranial high-grade glioma.

Intracranial meningiomas in the 9th decade of life: a retrospective study of 17 surgical cases.

The general availability of cerebral computed tomographic and magnetic resonance imaging scans makes the observation of symptomatic intracranial meningiomas in very elderly patients (aged 80 yr or more) relatively frequent. A few authors have reported on patients who have undergone surgery for intracranial meningiomas in their 9th decade of life, without providing indications regarding the surgical criteria and the prognostic factors. We report on a series of 17 patients who have received surgery for intracranial meningiomas in their 9th decade of life, with the goal of determining some surgical criteria for general physicians and neurosurgeons. Patients with severe systemic disease and definite functional limitations (American Society of Anesthesiology Class III) had a major postoperative morbidity (P = 0.020) and mortality (P = 0.005), especially if they scored low (< 70) on the preoperative Karnofsky Rating Scale (P = 0.010). The risk of postoperative morbidity was higher when the maximum diameter of the tumor was > 5 cm (P = 0.031).
