NID1 variant associated with occipital cephaloceles in a family expressing a spectrum of phenotypes.

Am J Med Genet A 2019 May 17;179(5):837-841. Epub 2019 Feb 17.

Children's Hospital of Eastern Ontario Research Institute, University of Ottawa, Ottawa, Ontario, Canada.

Autosomal dominant Dandy-Walker malformation and occipital cephalocele (ADDWOC) is a rare, congenital, and incompletely penetrant malformation that is considered to be part of the Dandy-Walker spectrum of disorders. Affected individuals often present with an occipital cephalocele with a bony skull defect, but typically have normal neurological development. Here, we report on a three-generation family in which individuals have variable phenotypes that are consistent with the ADDWOC spectrum: arachnoid cysts in the proband and his maternal grandfather, an occipital cephalocele in the proband and his brother, and a small bony defect in the proband's mother.

WNT1-associated osteogenesis imperfecta with atrophic frontal lobes and arachnoid cysts.

J Hum Genet 2019 Apr 28;64(4):291-296. Epub 2019 Jan 28.

Department of Pediatrics, Faculty of Medicine, Chiang Mai University, Chiang Mai, Thailand.

A rare form of osteogenesis imperfecta (OI) caused by Wingless-type MMTV integration site family 1 (WNT1) mutations combines central nervous system (CNS) anomalies with the characteristic increased susceptibility to fractures. We report an additional case where arachnoid cysts extend the phenotype, and that also confirms the association of intellectual disabilities with asymmetric cerebellar hypoplasia here. Interestingly, if the cerebellum is normal in this disorder, intelligence is as well, analogous to an association with similar delays in a subset of patients with sporadic unilateral cerebellar hypoplasia.

Cases of recurrent meningitis in elderly patients with a spontaneous cerebrospinal fistula have been reported, and in some of these patients, cystic lesions were thought to be the underlying cause. We report a case of recurrent meningitis in an 11-year-old Japanese girl with an arachnoid cyst in the petrous apex. Pulsation of the cystic lesion was thought to cause bone erosion, leading to the formation of a fistula. Read More

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.
