AI Article Synopsis
- Arachnoid cysts in the posterior fossa are rare compared to those in other brain areas.
- Spontaneous changes in size for posterior fossa arachnoid cysts have not been documented in English literature, despite cases in other locations.
- A case study presents a 41-year-old male whose midline posterior fossa cyst decreased in size and symptoms initially, but later enlarged, leading to worsened neurological issues.
Article Abstract
Arachnoid cysts of the posterior fossa are rather uncommon compared with their supratentorial counterparts. Spontaneous disappearance of middle cranial fossa arachnoid cysts has been reported but there are none in the English literature on the spontaneous fluctuation in size of a posterior fossa arachnoid cyst. We present a 41-year-old male, with a midline posterior fossa arachnoid cyst, which appeared to lessen in size spontaneously with complete disappearance of symptoms and then enlarged with a worsening in neurological status.

Primary intracranial extraosseous Ewing's sarcoma with intraspinal metastasis in children: illustrative case.
J Neurosurg Case Lessons

Department of Neurosurgery, Children's Hospital of Nanjing Medical University, Nanjing, Jiangsu, China.
Background: The diagnosis of intracranial extraosseous Ewing's sarcoma (EES) poses challenges due to the absence of specific clinical and imaging features prior to surgery. It is crucial to differentiate the tumor from other small round cell malignancies postoperatively.
Observations: A 7-year-old patient was admitted to the authors' hospital due to the in situ recurrence of a posterior fossa tumor more than 1 month after the initial surgery for headache.

Department of Radiology, Obstetrics and Gynecology Hospital, Fudan University, PR China.
Objectives: To clarify the prenatal magnetic resonance (MR) imaging characteristics of fetal intracranial haemorrhages (ICHs) in a large cohort and correlate them with birth outcomes.
Methods: We retrospectively reviewed MR images of fetuses with ICH on screening ultrasound (US) on picture archiving communication system (PACS) servers within a nearly ten-year period from two medical tertiary centres. The indications, main abnormal findings and coexistent anomalies were recorded by two experienced radiologists with census readings.

Ependymoma is the third most common brain tumour of childhood and historically has posed a major challenge to both pediatric and adult neuro-oncologists. Ependymoma can occur anywhere in the central nervous system throughout the entire age spectrum. Treatment options have been limited to surgery and radiation, and outcomes have been widely disparate across studies.

Purpose And Background: The trigeminal artery is a rare anatomical variant, representing an embryonic vestige of the anastomosis between the internal carotid artery and the posterior circulator system, that can be asymptomatic or could have vast clinical manifestations produced by insufficient flow or by vascular nervous conflicts. This study is an anatomical presentation of 3 trigeminal artery cases observed at Medimar Imagistic Services Constanta.
Methods: The 3 trigeminal artery cases were discovered on a 860 magnetic resonance angiographies (0.

Department of Biomedical Imaging and Image-Guided Therapy, Medical University of Vienna, Vienna, Austria.
Objective: To apply a network medicine-based approach to analyze the phenome of the prenatal fetal MRI and biometric findings in the Chiari II malformation (CM II) to detect specific patterns and co-occurrences.
Method: A single-center retrospective review of fetal MRI scans obtained in fetuses with CM II was performed. Co-occurrence analysis was utilized to generate a phenotypic comorbidity matrix and visualized by Gephi software.
