BACKGROUND AND PURPOSE: Paralysing lumbar disc herniation (LDH): what and when to do? Few studies have analyzed the optimal timing of surgery in case of paralysing LDH. METHODS: Twenty-four charts were retrospectively reviewed of patients suffering of LDH with severe motor deficit. RESULTS: There were 16 men and eight women. Mean age was 45.1 years. Seventeen patients suffered of lumbar pain, 15 of radicular pain and all of a severe motor deficit, implying mostly the ankle flexion (17 patients). LDH was most frequently located at L4/L5 or L5/S1 level. Surgery was proposed to all patients at the end of the consultation. Nine patients were operated within 48 hours. The mean interval between onset of motor deficit and operation was 20 days. The statistical analysis did not reveal any significant difference among different prognostic factors between the 17 patients with good motor recovery and the seven patients with poor motor recovery. In particular the operative delay did not appear to influence the degree of motor recovery. Literature review on paralysing LDH provides five published series since 1996, including 28 to 116 patients. Two series, including the single prospective one, conclude that the degree of recovery of motor function is inversely related to the degree and duration of motor deficit. CONCLUSIONS: Our retrospective series of 24 operated paralysing LDH did not reveal any prognostic factor for motor recovery. There is no evidence based medicine data in the literature about the optimal timing of decompressive surgery. A relative consensus exists among spine surgeons for paralysing LDH: since operative indication is obvious, surgery should be done as soon as possible. [less ▲]

BACKGROUND: Multiple choroid plexus papillomas (CPPs) are rare. Usually, they correspond to villous hypertrophy or metastasis occurring during cerebrospinal dissemination. Multiple CPPs have rarely been reported as synchronous tumors. CASE REPORT: Three synchronous CPPs were resected in a 59-year-old female 6 years after their first imaging description. Pathology showed mucus-producing CPP in all 3, 1 of the 3 presenting some signs of atypia. No p53 or hSNF5/INI1 mutation, or signs of polyoma viruses infection were found. CONCLUSION: Although no clear cause for the multifocality was found, the simultaneous presence of the three tumors and their benign histology suggest that they were synchronous and not metastatic. The issue of differentiating synchronous CPPs from metastatic CPP is discussed. [less ▲]

INTRODUCTION: It is not unusual for very small aneurysms (</=3mm) to be responsible for subarachnoid haemorrhage. In addition, modern imaging has increased diagnosis of those that are asymptomatic. Because of their spatial configuration and thin and fragile walls, very small aneurysms can be a sizeable challenge for both open surgical and endovascular treatment. Based on recent literature data, the present manuscript reviews treatment indications and the choice of treatment strategy to occlude these particular aneurysms. METHODS: Literature review concerning surgical and endovascular treatment of very small aneurysms (</=3mm). Arterial dissections and blister aneurysms were excluded. RESULTS: We found no study that systematically and specifically assessed surgical treatment of very small aneurysms. Investigations of endovascular treatment are almost exclusively retrospective, usually evaluating a small number of patients, and are limited by selection bias. Despite often contradictory results, it appears that very small aneurysms carry a higher risk of rupture during endovascular procedures and higher ensuing mortality, as compared to larger aneurysms. The use of more flexible coils and additional endovascular tools appears to reduce this risk. There is no study comparing surgical to endovascular treatment. CONCLUSION: Very small aneurysms carry higher treatment risks than larger aneurysms. A prospective randomised trial is justified for those very small aneurysms for which treatment is indicated.

BACKGROUND: The expanded endonasal approach of the cranio-cervical junction provides comfortable working space while avoiding some of the disadvantages of the transoral route. We report a purely endonasal endoscopic resection of the odontoid process for basilar invagination in a patient with a Chiari type I malformation, without posterior decompression or fusion. CASE REPORT: A 54-year-old female patient presented with cranial nerve and brainstem deficits. CT and MRI showed a Chiari type I malformation and compression of the medulla by basilar invagination of the odontoid process. The tip of the latter was displaced up to the bulbo-pontine sulcus. The odontoid process was resected via the expanded endoscopic endonasal approach, without additional posterior decompression or fusion. The post-operative course was uneventful, including the absence of velopharyngeal insufficiency. Neurological deficits regressed rapidly. The preoperative cervical pain virtually disappeared. At 9 months follow-up, the patient had normal activity with minimal residual neurological deficits. Post-op dynamic radiography and CT showed stability of the cranio-cervical junction. CONCLUSION: Decompression of the bulbomedullary junction by purely endoscopic transnasal resection of the odontoid process is well tolerated and efficient. Immediate stabilization is not mandatory in all cases of congenital causes of basilar invagination. [less ▲]

We describe a misleading case of a partially occluded A1 segment duplication that mimicked an ACoA aneurysm on computed tomography angiography and conventional angiography and led to surgical intervention. The location of such an anomaly at the ACoA on the side of least hemodynamic stress may provide a clue to recognizing this variant. [less ▲]

BACKGROUND AND PURPOSE: The clinical picture of hand atrophy related to a cervical rib or elongated C7 transverse process was well described in the modern literature by Gilliatt and Sumner; in 1970, they reported a series of nine patients whose motor status was stabilized following brachial plexus decompression. We report here seven patients suffering from thoracic outlet syndrome (TOS), who developed hand atrophy, sometimes because of diagnostic delay. METHODS: The patient's charts were analysed retrospectively. RESULTS: The seven patients were all female; the mean age was 43 years. The first complaints were arm pain and paresthesias lasting six months to 5 years. Three patients were treated with C56/C67 discectomy plus disc prosthesis (one patient), ulnar neurolysis at the elbow (the same patient), carpal tunnel release (one patient), and intravenous immunoglobulins (one patient) before TOS diagnosis. Hand atrophy, severe in five patients, was present at presentation. All patients underwent brachial plexus decompression by the anterior (four), posterior (two), or transaxillary (one) approach. This last approach was completed 18 months later by brachial plexus neurolysis via the anterior approach. Postoperatively, motor deficit was improved in two patients and stabilized in five patients. CONCLUSIONS: Physicians' unfamiliarity with TOS diagnosis or their reluctance to accept the diagnosis without electrical confirmation can lead to hand atrophy. Brachial plexus decompression at this stage usually stabilizes the deficit. [less ▲]

Intraventricular hemorrhage is common after the rupture of anterior communicating artery (ACoA) aneurysms, although the anatomical pathway has not been described. Knowledge of the mechanism of hemorrhage may enhance understanding of its prognosis. Using CT angiography, the authors analyzed this pathway in 2 cases of ACoA aneurysm rupture associated with intraventricular hemorrhage. The initial hemorrhages created a hyperdense ventriculographic image on which the subsequent contrast medium ejection could be followed. The contrast medium entered the subarachnoid space of the anterior interhemispheric fissure and broke through the lamina rostralis into the septum pellucidum and into the frontal horns of the lateral ventricles. Thus, the authors provide an explanation for bleeding from ACoA aneurysms into the ventricular system in the presence of an intact lamina terminalis. The septum pellucidum may act as a buffer before extension of the bleeding into the ventricular system. [less ▲]
