Cureus 2018 Sep 28;10(9):e3383. Epub 2018 Sep 28.

Neurosurgery, Advocate Christ Medical Center, Oak Lawn, USA.

Arachnoid cysts (ACs) are congenital, extra-axial lesions containing fluid similar to the composition of cerebrospinal fluid. Usually found incidentally, these lesions are observed with serial imaging to document their growth patterns and stability, and are then followed conservatively until clinical symptoms develop. Surgical options for symptomatic arachnoid cysts include cyst aspiration, cyst evacuation with fenestration into the subarachnoid space, and shunt procedures including cysto-peritoneal and cysto-ventricular shunts.

Glimpse into Pathophysiology of Sellar Arachnoid Cysts.

World Neurosurg 2018 Nov 24;119:381-383. Epub 2018 Aug 24.

Department of Neurosurgery, Monash Medical Centre and Surgery, Monash University, Melbourne, Australia.

Background: Sellar arachnoid cysts are a rare occurrence but may impinge on vital parasellar anatomy and thus are often symptomatic. The etiology of sellar arachnoid cysts is contentious, fueled by heterogeneity in cyst wall structure and contents between cases. The "ball-valve" mechanism is 1 of 2 predominant theories describing their formation, which contends that an aperture in the diaphragm allows cerebrospinal fluid to enter the cyst, propelled by pulsatile flow, but its egress is obscured by the pituitary during the ebb of the pressure wave.

Nontraumatic intradiploic arachnoid cyst of the sphenoid bone.

Radiol Case Rep 2018 Jun 8;13(3):576-579. Epub 2018 Mar 8.

Department of Radiology, Worcestershire Royal hospital, Worcester, WR3 7TB, UK.

The intradiploic arachnoid cysts are rare radiological entities which are generally post-traumatic in nature and occur mostly in occipital region. We present a rare case of non-traumatic, asymptomatic intradiploic cyst of the greater wing of sphenoid in an elderly patient. The CT and MR imaging confirmed an intraosseous multiloculated cystic lesion which showed communication with the cerebrospinal fluid in anterior temporal fossa, through the small bony defects.

Modified Pure Endoscopic Approach to Pineal Region: Proof of Concept of Efficient and Inexpensive Surgical Model Based on Laboratory Dissections.

World Neurosurg 2018 Sep 20;117:195-198. Epub 2018 Jun 20.

Department of Neurosurgery, Helsinki University Hospital, University of Helsinki, Helsinki, Finland.

Objective: In recent decades endoscopic techniques have been increasingly used in neurosurgery as they may offer a valuable close-up view of the working area through a minimally invasive surgical corridor. Herein, we present an inexpensive and efficient endoscopic surgical model using a borescope, which was used for a "modified pure endoscopic approach" to the pineal region.

Methods: A borescope video camera was connected to a 16-inch personal computer monitor. Read More

Fetal cerebellar disorders.

Handb Clin Neurol 2018 ;155:3-23

Fetal Neurology Clinic, Ob-Gyn Ultrasound Unit, Lis Maternity Hospital, Tel Aviv, Israel.

The embryologic development of the cerebellum extends over a long time period, thus making it vulnerable to a broad spectrum of malformations and disruptions. Knowledge of the main steps of fetal posterior fossa development; the normal imaging patterns at different stages of embryogenesis; the large spectrum of cerebellar malformations; and their clinical presentations enables diagnosis and precise counseling of parents. Sonography is the most important imaging method for the screening of cerebellar malformations since it is noninvasive, widely available, and safe for both mother and child. Read More

[Fetal magnetic resonance imaging].

Radiologe 2018 Jul;58(7):668-672

Klinik für Diagnostische und Interventionelle Neuroradiologie, Universitätsklinikum des Saarlandes, Kirrberger Straße, 66424, Homburg-Saar, Deutschland.

Clinical Issue: The most important prenatal screening method for the detailed assessment of the fetus is ultrasound, which is often combined with colour-coded Doppler sonography. In case of sonographically diagnosed fetal pathologies or technical limitations of the ultrasound, supplementary diagnostics may be necessary.

Standard Radiological Methods: With fast MRI sequences, fetal MRI screening provides important additional information especially with regard to the most common congenital pathologies-central nervous system (CNS) pathologies (agenesis of the corpus callosum, ventriculomegaly, arachnoid cyst, pathologies of the posterior cranial fossa, dysfunction of the gyrification).

Oktay Algin

J Comput Assist Tomogr 2018 Sep/Oct;42(5):816-821

From the Department of Radiology, Medical Faculty, Yildirim Beyazit University; and National MR Research Center (UMRAM), Bilkent University, Ankara, Turkey.

Purpose: Phase-contrast cine magnetic resonance imaging (PC-MRI) is a widely used technique for determination of possible communication of arachnoid cysts (ACs). Three-dimensional (3D) sampling perfection with application-optimized contrasts using different flip-angle evolutions (3D-SPACE) technique is a relatively new method for 3D isotropic scanning of the entire cranium within a short time. In this research, the usage of the 3D-SPACE technique in differentiation of communicating or noncommunicating type ACs was evaluated. Read More
