Cisto coloide no terceiro ventrículo e morte súbita em jovem

Morte súbita de jovem, sexo masculino, 23 anos, assintomático, suscitou verificação de óbito. Antes queixou-se de cefaleia excruciante, em sala de aula, caindo sobre o computador. Encéfalo apresentou edema e congestão vascular. Sem herniações. Cortes coronais evidenciaram dilatação dos ventrículos laterais e nódulo aderido ao teto do terceiro ventrículo. À microscopia o diagnóstico foi cisto coloide do terceiro ventrículo. A ameaça de morte súbita em portadores de cisto coloide é sério problema diagnóstico na emergência médica. A relevância deste caso está em lembrar aos médicos que esta entidade deve permanecer como diagnóstico diferencial nas cefaleias em crianças, adolescentes e adultos jovens.

Colloid cyst of third ventricle

1878-7649/$ – see front matter 2010 Elsevier Masson SAS and European Union Ger doi:10.1016/j.eurger.2010.07.014 Computed tomography (CT) without contrast product showed a 23 mmhyperdense spheric tumor of the third ventricle (Fig. 1). The cerebral Magnetic Resonance Imaging (MRI) described a ponto cerebellar ischemic stroke and a lesion hanging on the roof of third ventricle and hyperintense on T1 weighted sequence (Fig. 2). A voluminous colloid cyst was diagnosed. The patient progressively recovered of ataxia and dysarthria. An atrial fibrillation was diagnosed on electrocardiogram and treated with warfarin and a beta-blocker. She did not have previous symptoms suggesting colloid cyst as headaches. In agreementwith the neurosurgeon, the colloid cyst was not removed and a follow-up by CT scan was proposed. A colloid cyst is a quite unusual benign tumor that occurs within the third ventricle and can obstruct the cerebrospinal fluid flow [1]. The cyst size range from 2–50 mm and contains colloid material including cholesterol fats responsible of the MRI aspects. Associated signs and symptoms cover a wide range of features, from asymptomatic to intermittent headaches or less commonly nausea, gait disturbance or short-term memory loss. Some colloid cysts can lead to acute hydrocephaly and sudden death [1]. On CT the mass is usually hyper or isodense to grey matter while on MR

Neuro-endoscopic treatment for intraventricular cysts in children

Objective To study the technical key points and effects of neuro-endoscopic treatment for intravcntricular cysts in children, and to analyze the features of velocity and flux of cerebrospinal fluid in patients of intraventricular cysts. Method Cine MRI was used to analyze the velocity and flux of eerebrospinal fluid. Among all the cases,there were 8 lateral ventricles cysts,2 third ventricle cysts,4 fourth ventricle cysts, 2 suprasellar araehnoid cysts and 1 quadrigeminal cistern arachnoid cyst. The neuro-endoscopic operation was performed to all kinds of intraventricular cysts in order to study the indication, optimal process and clinical effects. Results The CSF dynamic states were improved in all patients. It was found that the CSF passed through the stoma after ETV in all patients. The contraction of cyst was found in 14 cases, and there was no notable change in 3 cases. The total effective rate was 82. 4%. There was no surgery -related serious complication. The cyst enlargement or stoma obstruction was not found in all patients after 3 -19 months follow-up period. Conclusions Cine MRI and radionuclide cisternography are helpful to understand the CSF dynamic states in children with intraventricular cysts and they are important references for surgery and determination of prognosis. Neuronavigated endoscopic surgery may be more precise and safe. Post-operative lumbar puncture is helpful to reconstruct normal CSF circulation and improve the prognosis.
