Which of the following is the anatomical location of foramen of Bochdalek?: (A) Mediastinum, (B) Urogenital diaphragm, (C) Diaphragm, (D) Dura mater
Answer is C. Foramen of Bochdalek is present on diaphragm. Posterolaterally, failure of fusion of the pleuroperitoneal canal creates a defect through which viscera may herniate to produce a foramen of Bochdalek hernia. Bochdalek hernia occurs more frequently on the left side and may cause severe respiratory distress at bih, requiring an emergent operation. Ref: Fisichella P.M. (2010). Chapter 20.
