RESUMEN
BACKGROUND: Delayed enhancing white matter lesions are a rare complication that develops after endovascular treatment of cerebral aneurysms, the etiology of which remains unclear. METHODS AND RESULTS: We present a 52-year-old female patient who was symptomatic with a seizure-like condition and showed reversible cranial parenchymal changes with high-dose cortisone treatment after endovascular stent-assisted coil embolization for an unruptured aneurysm in the internal cerebral artery. CONCLUSIONS: Clinicians should be alert to this rare complication and should follow patients for a long time due to its fluctuating and long-term course.

BACKGROUND AND OBJECTIVE: Rasmussen's encephalitis (RE) is a rare chronic neurological disorder, characterized by unilateral inflammation of the cerebral cortex, refractory focal epilepsy or epilepsia partialis continua, hemiparesis, and progressive cognitive decline. Interleukin-1 (IL-1) plays an important role in neuroinflammation as a key element in the activation of the inflammatory IL-1ß-IL-1 receptor type 1 (IL-1R1) axis. Anakinra, an IL-1 inhibitor, is successfully used in patients with new onset refractory status epilepticus and febrile infection-related epilepsy syndrome. METHODS AND RESULTS: We present 38-year-old male with RE having right-sided hemiparesis and continuous spasms being unresponsive to immune modulatory therapies like pulse steroid, intravenous immunoglobulin and anti-seizure drugs. After treatment with anakinra for three weeks, the continuous spasms almost completely subsided, and his muscle strength returned to normal. DISCUSSION: Anakinra may be considered as a treatment option in patients with RE and refractory seizures.

BACKGROUND AND PURPOSE: This study aimed to investigate the potential contribution of quantitative measurements of dural venous sinuses to the diagnosis of idiopathic intracranial hypertension (IIH) and the relationship between IIH and dural venous sinus dimensions on 3D post-gadolinium T1-weighted magnetic resonance (MR) images. MATERIAL AND METHODS: A total of 129 individuals (57 IIH patients and 72 controls) who complained of headache and underwent both magnetic resonance venography (MRV) and precontrast/postcontrast 3D T1-weighted MR imaging between 2018 and 2021 were included in this retrospective study. Dural venous sinus and jugular vein diameters were measured in all cases using post-gadolinium 3D T1 TFE images. The presence of transverse sinus (TS) hypoplasia and occipital sinus variation, the number and size of arachnoid granulations in the TS, and the presence of brain parenchymal herniation were also evaluated. Cut-off values that maximized accurate diagnosis of IIH were established on the receiver operating characteristic curve. The sensitivity and specificity of the diagnosis of IIH based on quantitative measurements of the dural sinus were calculated. RESULTS: The ratios of the maximum to minimum TS diameters and the minimum TS diameters to minimum sigmoid sinus (SS) diameters were significantly higher in IIH patients than in the control group (pâ¯< 0.001). The diagnostic sensitivity and specificity values of TSmax/TSmin and TSmin sum/SSmin sum parameters for the detection of IIH were 84.2%, 84.7% and 83.3%, 84.2%, respectively. CONCLUSION: Practical measurements from multiplanar T1 sequences can be useful for both quantitative assessment and overcoming misinterpretation due to anatomical variation.

BACKGROUND AND PURPOSE: COVID-19 is a novel infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in which neurological complications have been increasingly recognized. Acute symptomatic epileptic seizures and status epilepticus are frequently reported neurological complications associated with this infection. The nervous system damage caused by SARS-CoV-2 may be mediated by the immune system. Interleukin 6 (IL-6), an important component of the cytokine storm, is directly correlated with the severity of symptoms. Tocilizumab is an inhibitor of IL-6 receptors, which blocks IL-6-mediated signal transduction and is used in the treatment of COVID-19 and status epilepticus. CASE REPORT: A patient with the Unverricht-Lundborg disease is presented who had developed refractory recurrent status epilepticus during COVID-19 infection, which was finally controlled by treatment with tocilizumab. DISCUSSION: Tocilizumab, an IL-6 inhibitor, may be considered as a treatment option in patients with status epilepticus and refractory seizures.
