RT Journal Article SR Electronic T1 Proboscis lateralis with associated orbital cyst: detailed MR and CT imaging and correlative embryopathy. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1471 OP 1476 VO 13 IS 5 A1 L B Poed A1 L Hochhauser A1 C Bryke A1 B W Streeten A1 J Sloan YR 1992 UL http://www.ajnr.org/content/13/5/1471.abstract AB Proboscis lateralis is a rare craniofacial malformation. We present a case in a 1-week-old male infant, describe the clinical and imaging findings, and discuss the pertinent embryology. MR and CT proved to be complementary: CT provided anatomic detail in bone, defined the nasal cavity, and aided in determining the relationship of the proboscis and orbit; MR clarified the relationship of the proboscis to the orbit and skull base, and the relationships of normal brain to the dysplastic ethmoid centers.
