الملخص الإنجليزي
Pharyngocele is a rare pathology of the pharynx caused by the laxity of the thyrohyoid
membrane. Only about 60 true lateral pharyngocele cases have been reported in the
literature over the last 133 years. Laryngocele is a close differential, and the two are
difficult to tell apart. Though they have been described well in the literature, they are
often misdiagnosed or interchangeably diagnosed. The acquired type of pharyngocele
is due to prolonged increased intrapharyngeal pressure and pharyngeal wall weakness,
and it is more common than congenital pharyngoceles. Close differential diagnoses
include Zenker's diverticulum, laryngocele, and jugular venous phlebectasia. Acquired
lateral pharyngoceles are seen in wind instrument musicians and glassblowers. Hence,
these diverticula are described as 'overuse syndrome'. We present a case of bilateral neck
swelling, which occurred doing the Valsalva maneuver with imaging studies.
