We report our experience with 11 cases of foramen magnum meningiomas, eight originating inside the posterior fossa and three in the caudal region. The mean age of the patients was 50.8 years and the main complaint was cervical headache for at least 18.6 months and at the neurological examination, tetraparesis and deficit of the lower cranial nerves were very often observed. All patients were submitted to surgical treatment, always with exposition of the vertebral artery at the entry zone in the dura mater of the posterior fossa, with partial removal of the occipital condyle in only three cases. Total resection was obtained in seven patients and partial removal in the other four due to adherences to vessels and nerves. The prognostic was related to the neurological condition before surgery.

Background And Purpose: In idiopathic normal pressure hydrocephalus (iNPH) patients, cerebrospinal fluid (CSF) flow is typically evaluated with a cardiac-gated two-dimensional (2D) phase-contrast (PC) MRI through the cerebral aqueduct. This approach is limited by the evaluation of a single location and does not account for respiration effects on flow. In this study, we quantified the cardiac and respiratory contributions to CSF movement at multiple intracranial locations using a real-time 2D PC-MRI and evaluated the diagnostic value of CSF dynamics biomarkers in classifying iNPH patients.

Introduction: Klippel-Trenaunay Syndrome (KTS) is a rare congenital condition characterized by vascular malformations, bone abnormalities, and limb overgrowth. The genetic basis of KTS is not fully understood, and the diagnosis relies on clinical features. Its clinical spectrum includes several neurosurgical diagnoses, such as cavernous hemangiomas, arteriovenous fistulas, and Chiari I malformation.

Background: Postoperative subdural hematoma (SDH) typically presents with headache, impaired consciousness, hemiplegia, gait disturbance, and aphasia but can also present with visual impairment.
Observations: A 52-year-old woman diagnosed with Chiari malformation type I and syringomyelia underwent foramen magnum decompression. Cerebrospinal fluid was lost due to arachnoid injury during the procedure.

Background: Goldenhar syndrome is a clinically heterogeneous disorder defined by a rare combination of congenital anomalies-an eye abnormality, in addition to two of the following three: ear anomalies, mandibular malformations, and vertebral defects. Notably, children with Goldenhar syndrome present with a high incidence of cervical spine malformations.
Clinical Case: In this report, we present an unusual case of a 15-year-old child with Goldenhar syndrome, who additionally presents with some clinical features of VACTERL syndrome.

Background: Giant prolactinoma (size > 4 cm) is a rare condition and accounts for less than 1% of pituitary adenomas. In even rarer cases, these lesions may involve craniocervical structures requiring surgical intervention. The present case is the largest reported giant prolactinoma (99 × 72 × 57 mm).
