[Extra-axial chordoid meningioma: a case report]. / Méningiome chordoïde extra-axiale: à propos d'un cas.

This study reports the case of a 45-year-old female patient who underwent brain CT scan which fortuitously revealed de novo lesion. She was diagnosed with left isodense intradiploid lesion in the pterional region with bone lysis uniformly enhancing after injection of contrast medium. Magnetic resonance imaging showed T1-weighted hypointense lesion, spontaneously hyperintense signal on T2-weighted images and FLAIR images, strongly enhancing after gadolinium injection. Total tumor excision was performed. Histological examination showed chordoid meningioma.

Giant Arachnoid Cyst Associated with an Orbital Meningocele: A Case Report and Cystoperitoneal Shunt Management.

INTRODUCTION: Intracranial arachnoid cysts (ACs) are space-occupying lesions that typically remain stable in size and clinically silent over time. CASE REPORT: We describe an unusual pediatric case of enlarged AC impressive by its compressive phenomena. An 11-month-old girl presented with remarkable macrocephaly associated with a cystic orbital tumor. CT scan and MRI studies revealed a large intracranial ACs extending in the orbit with an orbital meningocele (OM). The intracranial cyst did communicate with the orbital one into a bony defect in the right inner region of the orbital roof and represses the globe outward. A cystoperitoneal shunting procedure was performed to remove the mass effect as soon as possible and facilitate normal development. DISCUSSION/CONCLUSION: Cysts in infants younger than 1 year of age are remarkably different from those in older children and adults in terms of cyst localization and enlargement. Classically described complications result from compression of adjacent structures and include focal neurologic involvement, headaches and seizures and developmental deficits, or macrocephaly in younger children. There are few cases of ACs with ophthalmic manifestations reported in the literature. The paucity of literature prompted us to analyze the case. To the best of our knowledge, an AC accompanying OM has not been reported. The pathogenesis and management of the case will be discussed.

Neurosyphilis revealed by compressive cervical spine syphilitic gumma: a case report.

INTRODUCTION: Neurosyphilis is a sexually transmitted disease secondary to the invasion of the central nervous system by the Treponema pallidum. The spinal syphilitic gumma is rare. CASE PRESENTATION: We report a case of extradural cervical spinal syphilitic gumma revealed by spinal cord compression in a 58-year-old male. The epidural lesion was removed via a posterior approach. Histological examination revealed syphilis. Syphilis serologies were positive. Brain MRI showed an associated cerebro-meningeal syphilitic gumma. Antibiotic regime based on aqueous penicillin G was introduced for 14 days. DISCUSSION: Currently, there is an increase in the frequency of syphilis and changes in its clinical manifestations. Neurosyphilis can take atypical forms. Spinal syphilitic gumma is a rare manifestation and its association with cerebral involvement is exceptional. Diagnosis is based on serologies in the blood and cerebrospinal fluid. The place of imagery, especially magnetic resonance imaging, is essential. Neurosyphilis should be discussed as a possible differential diagnosis in evaluation of spinal and cerebral lesions.

[Pseudo-tumor form of neuro-Behçet disease: case study and literature review]. / Une forme pseudo-tumorale du neuro-Behçet: à propos d'un cas et revue de la littérature.

Mass lesions of the brain are not always a tumor. We report the case of a patient followed for Behcet syndrome presenting with expansive intracranial process revealed by right hemiparesis associated with signs of intracranial hypertension. Brain magnetic resonance imaging (MRI) showed a lesion suggesting glial tumor. Clinical and radiological assessments as well as laboratory tests helped to establish the diagnosis of pseudo-tumor form of neuro-Behçet disease. This study report is followed by a clinical analysis based on the available literature on this disorder.
