Peripheral nerve lipoma: Case report of an intraneural lipoma of the median nerve and literature review.

Adipose lesions rarely affect the peripheral nerves. This can occur in two different ways: Direct compression by an extraneural lipoma, or by a lipoma originated from the adipose cells located inside the nerve. Since its first description, many terms have been used in the literature to mention intraneural lipomatous lesions. In this article, the authors report a case of a 62-year-old female who presented with an intraneural median nerve lipoma and review the literature concerning the classification of adipose lesions of the nerve, radiological diagnosis and treatment.

A simple scoring system for predicting early major complications in spine surgery: the cumulative effect of age and size of surgery.

OBJECTIVE: To analyze the cumulative effect of risk factors associated with early major complications in postoperative spine surgery. METHODS: Retrospective analysis of 583 surgically-treated patients. Early "major" complications were defined as those that may lead to permanent detrimental effects or require further significant intervention. A balanced risk score was built using multiple logistic regression. RESULTS: Ninety-two early major complications occurred in 76 patients (13%). Age > 60 years and surgery of three or more levels proved to be significant independent risk factors in the multivariate analysis. The balanced scoring system was defined as: 0 points (no risk factor), 2 points (1 factor) or 4 points (2 factors). The incidence of early major complications in each category was 7% (0 points), 15% (2 points) and 29% (4 points) respectively. CONCLUSIONS: This balanced scoring system, based on two risk factors, represents an important tool for both surgical indication and for patient counseling before surgery.

RESUMO Objetivo Analisar os efeitos cumulativos dos fatores de risco associados com complicações precoces graves relacionadas à cirurgia da coluna. Métodos Análise retrospectiva de 583 pacientes tratados cirurgicamente. Complicações graves foram definidas como as que pudessem levar a danos permanentes ou que necessitassem de reinterveção. Um escore foi construído usando modelo de regressão logística. Resultados Noventa e duas complicações precoces graves ocorreram em 76 pacientes (13%). Idade > 60 anos e cirurgia > 3 níveis foram identificadas como fatores de risco independentes na análise multivariada. O escore foi definido como: 0 pontos (nenhum fator de risco), 2 pontos (1 fator) ou 4 pontos (2 fatores). A incidência de complicação grave precoce em cada categoria foi 7% (0 pontos), 15% (2 pontos) e 29% (4 pontos). Conclusões Esse escore balanceado baseado em 2 fatores de risco representa uma ferramenta útil na indicação cirúrgica e para o aconselhamento dos pacientes antes da cirurgia.

Intracranial intrasellar kissing carotid arteries: case report.

Intracranial "kissing" carotid arteries are a rare variant of the carotid arteries, where both internal carotid arteries deviate medially and touch each other near the midline within the sphenoid sinus or the sphenoid bone, including the sella. This anomaly is particularly important since it may cause or mimic pituitary disease and also may complicate transsphenoidal surgery. We report a rare case of intracranial intrasellar kissing carotid arteries in a 57-years-old woman that was submitted to a computed tomography angiography during investigation of a sudden headache, and to discuss the clinical relevance of this radiological finding.

Artérias carótidas intracranianas "que se beijam" representam rara variação da anatomia arterial, onde ambas as artérias carótidas internas desviam-se medialmente e tocam-se próximo à linha media dentro do seio esfenoidal ou do osso esfenóide, incluindo a sela túrcica. Essa anomalia é particularmente importante, pois pode causar ou simular doença pituitária e ainda pode complicar uma cirurgia transesfenoidal. Relatamos um raro caso de artérias carótidas intracranianas "que se beijam" em mulher de 57 anos, a qual foi investigada por angiotomografia por quadro de cefaléia súbita. Discutimos a relevância clínica desse achado radiológico.

Primary meningeal Burkitt-type lymphoma presenting as the first clinical manifestation of acquired immunodeficiency syndrome.

The purpose of this study is to report a rare case of primary meningeal high grade Burkitt-type lymphoma presenting as the first clinical manifestation of acquired immunodeficiency syndrome. A 38-year-old Caucasian man, with a negative past medical history, sought treatment after experiencing global headache for five days. CT-Scan revealed a right front-temporo-parietal hyperdense subdural expansive mass. A craniotomy was performed and a hard white subdural was microsurgically dissected. Some hours after the surgery, the patient developed hemispheric cerebral edema and intracranial hypertension syndrome. Decompressive craniotomy was performed and the patient had an excellent recovery. Screening blood tests diagnosed human immunodeficiency virus infection. Further investigation ruled out systemic diseases. Eleven days after the initial surgery, the patient developed an acute respiratory failure and sepsis, dying on that day. Pathological studies diagnosed Burkitt-type lymphoma.

Primary meningeal Burkitt-type lymphoma presenting as the first clinical manifestation of acquired immunodeficiency syndrome

O objetivo desse estudo é relatar um caso de linfoma de Burkitt de alto grau primitivo da meninge, que se apresentou como primeira manifestação clínica da síndrome de imunodeficiência adquirida. Um homem branco, de 38 anos, previamente hígido, referia cefaléia holocraniana há cinco dias. A TC de crânio evidenciou coleção hiperdensa subdural na região fronto-temporo-parietal direita. Após craniotomia fronto-temporal direita, um tumor branco e rígido de localização subdural foi microcirurgicamente ressecado. Algumas horas após, o paciente apresentou edema cerebral hemisférico e hipertensão intracraniana, tendo sido submetido à craniotomia descompressiva com excelente melhora clínica. Testes sorológicos evidenciaram infecção por vírus da imunodeficiência humana. Investigações complementares afastaram outras doenças sistêmicas. Onze dias após a primeira cirurgia, o paciente apresentou insuficiência respiratória aguda e sepse, evoluindo para o óbito. Análise histopatológica evidenciou linfoma de Burkitt.
