Are the metabolic characteristics of congenital intraspinal lipoma cells identical to,or different from normal adipocytes?

Congenital intraspinal lipomas are frequently responsible for progressive neurological deficits caused by distortion or compression of the nervous system. Since fat metabolism in these lesions has not been previously studied, the aim of this study was to determine whether intraspinal lipoma cells behave like lipomas or like normal adipocytes. In 11 patients, intraspinal lipoma cells were compared with normal adipocytes isolated from adjacent subcutaneous adipose tissue for the following parameters: lipoprotein lipase (LPL), lipogenesis from U¹⁴C glucose, ß-receptor number, adenylate cyclase activity, cyclic AMP production, and lipolysis in response to ß- and ₂-adrenergic agonists. No significant difference between these two cell populations was found, suggesting that intraspinal lipomas are not lipomatous tumors, but hamartomatous lesions capable of growth and regression along with the changes in the rest of the fatty pool. This emphasizes the danger of an abnormal weight gain, as well as the possible usefulness of an hypocaloric diet in patients who worsen in spite of previous surgery.Research supported by INSERM (CRL 824005 and CRE 854010) and the D.G.R.

Spinal Papillary Meningioma: A Case Report and Review of the Literature

Summary  A rare case of a spinal papillary meningioma in a 19-year-old adolescent is described. Six months after radical resection the patient showed dissemination along the cerebrospinal pathway. Papillary meningiomas are rare tumours with a relatively high incidence in childhood. Most papillary meningiomas reported in the literature are considered as aggressive variants of meningioma with often local recurrence, dissemination in the CSF and metastases to remote sites. This case supports that, although the histogenesis remains unexplained, papillary meningiomas deserve recognition on the basis of their high morbidity and mortality.     

Intraspinal anomalies: presentation,assessment, treatment and association with the development of scoliosis

The most common congenital intraspinal abnormalities presenting to medical attention is either a Chiari malformation with or without associated syringomyelia or caudal anomalies, such as tethered cord and fatty filum terminale. These intraspinal defects are usually diagnosed at birth or in early childhood, but they may also be identified in adult life due to newly presented neurological symptoms. Availability and use of appropriate imaging modalities, such as MRI and regular fetal screening has reduced the incidence of delayed diagnosis of spinal dysraphism and other accompanying congenital systemic anomalies. In view of the risk for neurological complications, prophylactic surgery is often recommended in spinal dysraphism; hence knowledge of various intraspinal abnormalities, their clinical presentation and natural history will allow early diagnosis and treatment in order to prevent neurological deterioration and irreversible morbidity. This review summarizes the embryological aspects and clinical manifestations of intraspinal abnormalities and provides a rational approach for evaluation and management in this group of patients.     

Is it safe and effective to correct congenital scoliosis associated with multiple intraspinal anomalies without preliminary neurosurgical intervention?

The aim of the study was to determine if multiple intraspinal anomalies increase the risk of scoliosis correction compared to the normal intraspinal condition or 1 or 2 intraspinal anomalies in congenital scoliosis (CS) and whether correction for multiple intraspinal anomalies need to be performed with preliminary neurosurgical intervention before scoliosis correction.A total of 318 consecutive CS patients who underwent corrective surgery without preliminary neurosurgical intervention at a single institution from 2008 to 2016 were retrospectively reviewed, with a minimum of 2 years of follow-up. The patients were divided into 3 groups according to different intraspinal conditions. In the normal group (N group; n = 196), patients did not have intraspinal anomalies. In the abnormal group (A group; n = 93), patients had 1 or 2 intraspinal anomalies. In the multiple anomaly group (M group; n = 29), patients had 3 or more intraspinal anomalies including syringomyelia, split cord malformation [SCM], tethered cord, low conus, intraspinal mass, Chiari malformation or/and arachnoid cyst. The occurrence of complications as well as perioperative and radiographic data were analyzed.The incidence rate of multiple intraspinal anomalies in CS patients was 9.1% (29/318). No significant difference was observed in the perioperative outcomes or radiographic parameters at the final follow-up. There were no significant differences among the 3 groups in the total, major or neurological complication rates (all P > .05). Two patients (1 in the N group and 1 in the A group) experienced transient neurological complications, whereas no patient experienced permanent neurological deficits during surgery or follow-up.To our knowledge, the current study reported the largest cohort of intraspinal anomalies in patients with CS that has been reported in the literature. The results of our study demonstrated that patients with congenital scoliosis associated with intraspinal anomalies, even multiple intraspinal anomalies that coexist with more complex intraspinal pathologies, may safely and effectively achieve scoliosis correction without preliminary neurological intervention. More complex intraspinal pathologies do not seem to increase the risk of neurosurgical complications during corrective surgery.
