• Cervical herniation of the lung is a rare condition that results from congenital agenesis of Sibson fascia. Occasionally, this may result from acquired causes like trauma.1 We report a rare case of a patient who was recently encountered in our Otorhinolaryngological Clinic and who posed an interesting problem of differential diagnosis. The management of such patients requires frequent checkups to safeguard against spontaneous pneumothorax. An otolaryngologist should not be caught unaware as the rhythmic "ballooning" of the supraclavicular area is quite characteristic with forced expiration.
