Giant arachnoid cyst in adult presented with secondary epileptiform activity

Background: Current studies contain controversies regarding indications and preferable surgical techniques for arachnoid cysts. Case Description: In this paper we present case report of giant arachnoid cyst of right frontal lobe in young left-handed adult with headache, MRI sings of brain compression and epileptiform activity on EEG, treated by microsurgical cystostomy. Conclusion: We add a case of young adult with tension headaches and possible sub-clinical seizures due to arachnoid cyst, whose symptoms disappeared after surgical management of the cyst, including normalization of EEG.

Intracranial meningioma in a pet rat: MRI findings

We herein report the magnetic resonance imaging (MRI) findings in a brain meningioma in a pet rat (Rattus norvegicus domestica). A 1.5-year-old pet rat was referred for depression, ataxia, tremors and bilateral nystagmus; a brain MRI was elected suspecting an intracranial neoplasia. The study was performed with a 0.25 T scanner. The MRI revealed a well-defined oval mass with a heterogeneous appearance, hyperintense in T1 and T2, and with extra-axial localisation and severe brain compression, the mass appeared strongly and diffusely contrast-enhancing. Euthanasia was elected, with the necropsy confirming the presence of a voluminous extra-axial mass. Histologically, a well-differentiated, benign meningotheliomatous meningioma was diagnosed, with the histochemical stains allowing one to exclude a granular cell tumour. To the best of our knowledge, this is the first report of MRI investigations on a pet rat intracranial meningioma.

Gigli saw facilitates safe minimal access sagittal suturectomy in infants

The authors describe the use of the Gigli saw for craniectomy in minimal access surgery to address sagittal craniosynostosis. This modification allows for supine positioning and avoidance of potential brain compression with endoscopic instruments, and provides visually clear, safe, and facile removal of the fused suture and surrounding calvaria.

Chronic subdural hematomas: challenges and solutions. Part I. Clinical variants and diagnosis

Chronic subdural hematoma (cSDH) is a multifactorial extensive intracranial hemorrhage, causing the local and/or general brain compression. Hematoma has a delimiting capsule, which defines all pathophysiological features, clinical course and treatment tactics. The paper reports contemporary views on ethiology and clinical course of cSDH. Emphasis is placed on the diagnosis. Based on the analysis of 558 verified cSDH observations, the phasal course and brain imaging data are reported. CT and MRI signs of cSDH are defined.
