Acute presentation of Chiari malformation type I in adulthood with arm swelling, a case report and literature review.

INTRODUCTION: Chiari malformation type I (CM-I) with cervicothoracic syringomyelia can progress slowly this condition which is very common in clinical practice, particularly in children. CASE PRESENTATION: Patients typically present with chronic complaints, including headache, dizziness, and numbness, although are few reports in the literature describing pediatric patients who developed acute neurological deficits caused by CM-I. Here, we report an unusual presentation of this condition; the patient presented with sudden onset arm swelling with no precipitating factors that could explain the diagnosis. DISCUSSION: This is an illustrated case report and literature review. The patient's condition improved post-operatively; in terms of arm and hand swelling which resolved, but he still complained of persistent numbness on a follow-up visit.

Outcomes of resective surgery in pediatric patients with drug-resistant epilepsy: A single-center study from the Eastern Mediterranean Region.

OBJECTIVE: Epilepsy surgery is widely accepted as an effective therapeutic option for carefully selected patients with drug-resistant epilepsy (DRE). There is limited data on the outcome of epilepsy surgery, especially in pediatric patients from the Eastern Mediterranean region. Hence, we performed a retrospective study examining the outcomes of resective surgery in 53 pediatric patients with focal DRE. METHODS: Patients with focal DRE who had undergone epilepsy surgery were included in the present study. All patients underwent a comprehensive presurgical evaluation. Postoperative seizure outcomes were classified using the Engel Epilepsy Surgery Outcome Scale. RESULTS: After surgery, 33 patients (62.2%) were Class I according to the Engel classification of surgical outcomes; eight patients (15.0%) were Class II, 11 (20.7%) were Class III, and one (1.8%) was Class IV. The relationships of presurgical, surgical, and postsurgical clinical variables to seizure outcomes were compared. Older age at seizure onset, older age at the time of surgery, the presence of focal to bilateral tonic-clonic seizures, seizure duration over 2 minutes, unsuccessful treatment with three or fewer antiseizure medications, lesions confined to one lobe (as demonstrated via magnetic resonance imaging [MRI]), surgical site in the temporal lobe, and histopathology including developmental tumors were significantly linked to an Engel Class I outcome. A univariate analysis of excellent surgical outcomes showed that lateralized semiology, localized interictal and ictal electroencephalogram (EEG) discharges, lateralized single-photon emission computed tomography and positron emission tomography findings, and temporal lobe resections were significantly related to excellent seizure outcomes. SIGNIFICANCE: The results of our study are encouraging and similar to those found in other centers around the world. Epilepsy surgery remains an underutilized treatment for children with DRE and should be offered early.

Meningioma Presenting with Spontaneous Subdural Hematoma: A Report of Two Cases and Literature Review.

BACKGROUND: Although meningiomas are considered benign, encapsulated brain tumors, their distinct intracranial location can lead to devastating complications. Although a highly vascularized tumor, a rarely reported complication of meningioma is hemorrhage. To the best of our knowledge, only 19 cases of meningioma presenting with a subdural hematoma have been reported. CASE DESCRIPTION: We have outlined the clinical presentation, radiological findings, and outcomes of 2 female patients with a diagnosis of a spontaneous subdural hematoma associated with meningioma. The coagulation profile was within normal limits for both patients. The postoperative histopathologic examination results showed an angiomatous/microcystic subtype of meningioma (patient 1) and meningothelial meningioma (patient 2). Both patients underwent right frontal craniotomy, resection of the dural-based tumor, and evacuation of the subdural hematoma. CONCLUSIONS: We comprehensively reviewed the pertinent data for meningiomas presenting as subdural hematomas. The mechanism of hemorrhage in meningiomas remains unclear. Therefore, further studies are required to investigate the possible mechanisms of bleeding in such tumors.
