Page 914, Figure 11: The drawing for Figure 11d was inadvertently substituted and repeated for Figure 11c. The correct drawing for Figure 11c, as well as the other drawings of Figure 11, are reprinted correctly here with the accompanying legend.

Figure 11a. Faulty development of the nasofrontal region leading to formation of various midface masses. (a) Schematic illustrates how dermal sinus tracts form when there is no involution or only partial involution of the dural diverticulum that extends through the foramen cecum to the columella. Dermoid and epidermoid cysts may form anywhere along the course of the dermal sinus tract owing to desquamation of tissue lining the tract. (b) Schematic illustrates how nasal gliomas form when the dural diverticulum that extends through the foramen cecum does not retract and involute normally, leaving sequestered neurogenic tissue that may be connected to the intracranial contents by a fibrous stalk. (c) Schematic illustrates how frontonasal encephaloceles form when the fonticulus nasofrontalis remains patent. (d) Schematic illustrates how nasoethmoidal encephaloceles form when the foramen cecum fails to close and the prenasal space remains patent. (Reprinted, with permission, from reference 5.)

"MR Cholangiopancreatography of Bile and Pancreatic Duct Abnormalities with Emphasis on the Single-Shot Fast Spin-Echo Technique"
RadioGraphics 2000; 20:939–957
Pages 946-947 and 1107: The answer for question 8 of the test that accompanied this article (page 1107, column 2, last question) is contained in the article text on pages 946–947. The correct answer is c. The author conceded that the choice between answers c and d might be somewhat ambiguous and provided the following explanation for clarification: "Answer d is true [thus not the correct answer] because as stated in the article [page 946, column 2, last sentence], 'MRCP can be more accurate in demonstrating peripheral duct abnormalities, especially when proximal strictures preclude opacification of the peripheral biliary tree at ERCP.' ERCP may underestimate the degree of obstruction if the biliary tree is incompletely evaluated such as in cases of hilar stricture."
