Spontaneous arachnoid cyst rupture in a previously asymptomatic child: a case report

Arachnoid cysts are benign congenital cavities arising in the subarachnoid space. Non-traumatic subdural effusion of cerebrospinal fluid is a rare complication requiring surgical treatment. Case Report: A 15-year-old boy was admitted to the hospital because of symptoms related to acute intracranial hypertension (headache and vomiting). The cerebral CT-scan revealed a subdural hygroma adjoining a voluminous Sylvian arachnoid cyst. Two arachnoid cysts were incidentally discovered 11 years before this dramatic complication. Moreover, the patient had suffered a cerebral concussion 2 years earlier, but interestingly did not develop cystic hemorrhage or rupture, contrary to numerous cases previously described in the literature. The location of the cysts and their regular follow-up did not allow foreseeing a cystic rupture. Hygroma evacuation was first performed after which a subdural peritoneal. shunting, using a programmable opening pressure valve, was implanted. Spontaneous rupture into the subdural space represents an unusual complication of arachnoid cysts. Clinical aspects, radiographic findings, pathogenesis and surgical management are described. It is important to point out that subdural hygroma or haematoma should never be excluded in the absence of trauma history, even in the case of small non-progressive cysts regularly supervised.

La tachycardie ventriculaire catecholergique du jeune enfant: un diagnostic souvent meconnu

in Archives de Pédiatrie (2003), 10(6), 524-526

Catecholaminergic polymorphic ventricular tachycardia is important to be diagnosed as an underlying disease in children with syncope and normal heart, because of its poor prognosis. CASE REPORT: A 3-year ... [more ▼]

Catecholaminergic polymorphic ventricular tachycardia is important to be diagnosed as an underlying disease in children with syncope and normal heart, because of its poor prognosis. CASE REPORT: A 3-year-old boy was referred for stress and emotion induced syncope. Primary ventricular arrhythmia, consisting of salvos of bidirectional ventricular tachycardia, was reproducibly induced by physical exertion. The syncopal events and severe arrhythmia disappeared with beta-blocking therapy. CONCLUSION: Despite its rare occurrence, catecholaminergic polymorphic ventricular tachycardia is an important cause of stress and emotion induced syncope and sudden death in children. [less ▲]

Comment j'explore certains cas difficiles de meningite tuberculeuse

To formally document the presence of the bacillus of Koch in meninges still remains difficult and depends on many variables. We report two cases where the diagnosis proved difficult. The presentation of tuberculous meningitis can take several aspects. Mantoux reaction is frequently negative. The BK cultures, which demonstrate the diagnosis, depend on the volume of CSF and on the importance of BK dissemination. It, unfortunately, remains difficult to make the diagnosis of tuberculous meningitis even though this pathology can have extremely deleterious consequences. [less ▲]

Infantile and juvenile presentations of Alexander's disease: a report of two cases.

in Acta Neurologica Scandinavica (1999), 99(3), 158-65

We describe 2 new cases of Alexander's disease, the first to be reported in Belgium. The first patient, a 4-year-old girl, presented with progressive megalencephaly, mental retardation, spastic tetraparesis, ataxia and epilepsy: post-mortem examination showed widespread myelin loss with Rosenthal fibers (RFs) accumulation throughout the neuraxis. She was the third of heterozygotic twins, the 2 others having developed normally and being alive at age 5 years. The second patient developed at age 10 years and over a decade spastic paraparesis, palatal myoclonus, nystagmus, thoracic hyperkyphosis and thoraco-lumbar scoliosis with radiological findings of bilateral anterior leukoencephalopathy. Brain stereotactic biopsy at age 16 years demonstrated numerous RFs. With these 2 cases, we review the literature on the various clinico-pathological conditions reported as Alexander's disease. We discuss the nosology of this entity and the pathogeny of RFs formation and dysmyelination. Clues to the diagnosis of this encephalopathy in the living patient are briefly described. [less ▲]
