Sample item

A patient has a pulsion diverticulum arising below the cricopharyngeus on the lateral wall of the cervical oesophagus. What is the site called?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Killian-Jamieson space

The Killian-Jamieson space is a weak area in the anterolateral wall of the cervical oesophagus just below the cricopharyngeus, where the recurrent laryngeal nerve enters. It is a rarer site for diverticula than Killian's dehiscence above the cricopharyngeus. Such diverticula are usually small and lateral.

Option by option

  • A. Killian's dehiscence

    Killian's dehiscence lies above the cricopharyngeus posteriorly.

  • B. Killian-Jamieson space (correct)

    Correct. The space lies below cricopharyngeus on the lateral wall.

  • C. Sinus of Morgagni

    The sinus of Morgagni is the gap above the superior constrictor through which the eustachian tube and levator palati pass.

  • D. Laimer's triangle

    Laimer's triangle is on the posterior wall below the cricopharyngeus.
