Cephaloceles and related malformations.

چکیده
This chapter addresses the gross pathology and imaging of anencephaly, exencephaly and cephaloceles, and includes the clinical , epidemiologic, and pathologic features that have helped the authors to understand these conditions and to contribute meaningfully to their diagnosis and management. This paper specifically excludes the fronto-ethmoidal (sincipital) cephaloceles, the related nasal gliomas and nasal dermal sinuses, and the median cleft face syndrome, because these subjects have already been reviewed, in detail, in the American College of Radiology Self-Evaluation Program No. 28, Neuroradiology Text and Syllabus (1), in texts (2-6), and in articles (7-22).

A newborn with one anatomic malformation should be evaluated for associated anomalies. Total and direct bi...
متن کاملDilation of the subarachnoid spaces surrounding the cranial nerves with petrous apex cephaloceles in Usher syndrome.
Limited studies of brain MR imaging findings in Usher syndrome have reported atrophy with enlarged subarachnoid spaces. However, the specific appearance of the subarachnoid spaces surrounding the cranial nerves has not yet been described. Herein we describe the skull base MR imaging findings in an adult with Usher syndrome. Multiple cranial nerve exits were enlarged to the point of causing ceph...
متن کاملThe Chiari malformations.
Dr Hans Chiari 1 first described three hindbrain disorders associated with hydrocephalus in 1891. They have neither an anatomical nor embryological correlation with each other, but they all involve the cerebellum and spinal cord and are thought to belong to the group of abnormalities that result from failure of normal dorsal induction. These include neural tube defects, cephaloceles, and spinal...
