Intracranial inflammatory pseudotumour related to IgG4: A very rare case.

Background: Intracranial inflammatory pseudotumours (IPT) are rare entities that frequently lead to misdiagnosis with malignant lesions. The identification of these lesions is difficult, but important to avoid inadvertent iatrogenicity and to adjust therapeutic protocols.

Case Presentation: We report the case of a 30-year-old man who presented a single tonic-clonic seizure.

Exploring Rare Traumatic Injuries: A Miniseries of 4 Cases Discussing Epidural Hematomas Bridging the Infratentorial and Supratentorial Regions.

Supratentorial-infratentorial epidural hematomas (SIEH) are a rare occurrence following traumatic head injuries, representing only 2% of traumatic epidural hematomas. Given the unique anatomical characteristics of the infratentorial region, mainly its small size, surgical intervention is commonly undertaken to alleviate the pressure on the posterior fossa components. Consequently, there is ongoing debate surrounding the optimal surgical approaches.

Pediatric head injuries: particularities and neurosurgical experience in a lower-middle income country.

Purpose: To the best of our knowledge, this is the first study conducted in Tunisia on the neurosurgical management of child cranial trauma. The objectives of the present work were to identify the causes of pediatric head injuries, explore epidemiological and clinical specificities, and analyze the short- and long-term postoperative evolution.

Methods: A retrospective review was conducted on one hundred children with head injuries over a five-year period at one of the largest neurosurgery departments in Tunisia.

A Spectacular Penetrating Craniocerebral Trauma From a Rake: A Case Report.

Penetrating intracranial foreign bodies are rare and have a high potential for death or serious morbidity. Their surgical management is complicated and challenging. Herein, we present the case of a 30-years-old man who was a victim of aggression from a rake blow to the head.

Aseptic ascites and chemical meningitis following ventriculoperitoneal shunting for craniopharyngioma: A first case report.

We report the case of a 4-year-old boy who had a ventriculoperitoneal shunt due to hydrocephalus related to a cystic craniopharyngioma. Postoperative, he presented abdominal distension and meningismus. Imaging showed regression of the tumor.

Asymmetric Bilateral Traumatic Epidural Hematoma: A Report of a Rare Traumatic Lesion.

Bilateral epidural hematoma is a rare presentation in head trauma injuries, accounting for only 1%-2% of all epidural hematomas, but with a higher mortality rate than the unilateral form. Herein, we report the case of a 27-year-old man admitted to our department following a road traffic accident. On admission,his Glasgow Coma Scale (GCS) score was 13/15.

Hydrocephalus associated to posterior fossa tumor-like sarcoidosis: A case report and literature review.

Background: Intracranial inflammatory pseudotumors (IIPT) are one of the differential diagnosis for the central nervous system (CNS) tumors. They represent a rare condition that may mimic clinically and radiologically intracranial tumors and induce their complications. Among their etiologies, neurosarcoidosis is one of the less known and less frequent.

Polyuria and polydipsia revealing a pituitary metastasis: Report of a rare case.

Sellar region is a rare localization for intracranial metastases. The diagnosis is frequently delayed as symptoms are generally non specific. Radiologic diagnosis may be difficult as these tumours present similiraities to other more frequent sellar tumours.

Transdural spinal cord herniation: A rare cause of neurologic impairment: Report of two cases and review of the literature.

Introduction: Herniation of the thoracic spinal cord is a rare pathology related to the genesis of a breach in the anterior dura. Adding to the previously published cases, we report our department's experience with 2 cases of young adults who presented with transdural spinal cord herniation following spinal trauma.

Presentation Of The Cases: We report the cases of 2 men aged 27 and 57, with history of spinal trauma, who presented diverse clinical complaints (motor impairment, genito-sphincteric disorders, etc.

Cerbellar medulloblastoma in the elderly: Case report and review of the literature.

Introduction: Medulloblastoma is a malignant tumor of the posterior fossa which is mainly found in children aged less than 15 years of age. This tumor is uncommon in adults, especially those above 40 years old. We report the very rare case of a 61 years-old woman who was diagnosed with a cerebellar medulloblastoma.

Pneumocephalus after posterior fossa surgery in prone position: Is that any clinical effect?

Introduction: The term pneumocephalus refers to the existence of air in any intracranial compartment. Its presence in the follows of a supratentorial craniotomy is very common, and it usually represents a benign complication as it is very rarely responsible for clinical manifestations.

Case Presentation: We report the case of a 24 years-old man, who underwent posterior fossa surgery in prone position for resection of a vermian tumor.

Unintentional direct intraventricular injection of gadolinium with fatal outcome: report of a case.

Gadolinium diethylenetriamine penta-acetic acid (Gd-DTPA) is the main contrast agent used in MRI, known for its good tolerance and rare toxicity. Even intrathecal injection of limited doses of Gadolinium can be performed in some indications. To our knowledge, only 3cases of accidental intraventricular injection of Gadolinium have been yet reported in the literature.

About a rare pediatric case of myxoid meningioma.

Intracranial meningiomas are uncommon in the pediatric group. Myxoid meningioma is a subtype of metaplastic meningioma. It is the rarest WHO grade I meningioma.

Ischemic stroke following operated head trauma in children: Discussion of a rare clinical case.

Introduction: Traumatic brain injury (TBI) is the leading cause of morbidity and mortality in children. TBI in children are responsible for a range of clinical symptoms and signs that are comparable to those in adults, but present several differences in both physiopathology and management. Many postoperative complications may occur, ischemic stroke among others, which is generally related to an injury of an intracranial artery.

Management of a recurrence of a squamous cell carcinoma of the scalp with extension to the brain: A case report and literature review.

Background: Squamous cell carcinoma (SCC) is the most common form of nonmelanoma skin cancer after basal cell carcinoma. Simple excision can be the treatment at early stages of diagnosis. However, at late stages, treatment is more complex due to extension to the skull and the dura.

Pediatric Cerebellar Pilomyxoid Astrocytoma: Clinical and Radiological Findings in Three Cases.

Pilomyxoid astrocytomas (PMA) is a particular form of glial tumors distinct from pilocytic astrocytomas (PA). On the last 2016 WHO classification for CNS tumours, no definite grade assignment was proposed for these lesions. They may be more aggressive with a different clinical course compared to PA due to their greater propensity for local recurrence and cerebrospinal dissemination.

Iatrogenic Epidermoid Cyst of the Cauda Equina: A Late Complication of Lumbar Disc Herniation Surgery.

Background: Epidermoid cysts (ECs) account for 0.5% to 1% of all spinal tumors. They can be congenital or acquired.

Epidural angiolipoma: A rare cause of spinal cord compression.

Introduction: Angiolipomas are benign, slow growing lesions, almost always located subcutaneously in the trunc or limbs. They are composed of mature lipocytes admixed with abnormal blood vessels. Spinal epidural angiolipoma are rare accounting for approximately 0.
