Case Of the Week (COW) 11 Aug 2013
Answer:
ATELECTATIC RIGHT UNCINATE PROCESS
Findings:
volume loss of the right maxillary sinus with sinus opacification and infundibular obstruction is noted. The right uncinate process is apposed to the inferomedial aspect of the orbit . The free edge is seen adhering to orbital floor with closure of infundibulum.
Discussion:
The above constellation of findings are consistent with Atelectatic Uncinate Process. This in combination with painless enopthalmos and inferior orbital wall retraction is termed as Silent Sinus Syndrome. The treatment for this condition is endoscopic maxillary antrostomy . The radiologist must be aware of this rare entity , though well known to the opthamologist and ENT surgeon.
