Abstract
A postoperative intradiploic arachnoid diverticulum secondary to endoscopic third ventriculostomy is an extremely rare occurrence. It has a varied clinical presentation and is caused by the insinuation of the arachnoid through the dural rent into the intradiploic compartment following the procedure. This case report describes an incidentally diagnosed right parietal intradiploic arachnoid diverticulum as a complication of endoscopic third ventriculostomy. Skull radiography revealed an expansion of the right parietal bone with an intact outer table. Non-contrast computed tomography showed a well-defined cystic lesion in the intradiploic compartment, accompanied by expansion of the right parietal bone. A subsequent magnetic resonance imaging distinguished it from an epidermoid cyst. Knowledge of this rare entity is cardinal for early diagnosis and management, required to prevent potential neurological sequelae.
期刊介绍：
Official Journal of the European Society of Pediatric Radiology, the Society for Pediatric Radiology and the Asian and Oceanic Society for Pediatric Radiology
Pediatric Radiology informs its readers of new findings and progress in all areas of pediatric imaging and in related fields. This is achieved by a blend of original papers, complemented by reviews that set out the present state of knowledge in a particular area of the specialty or summarize specific topics in which discussion has led to clear conclusions. Advances in technology, methodology, apparatus and auxiliary equipment are presented, and modifications of standard techniques are described.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
