Background: Bochdalek hernias are a rare form of diaphragmatic hernias; they are frequently found in children; however, they have been discovered in completely asymptomatic adults in exceptional situations. Being such a unique pathology, they can be easily confused and misdiagnose, exposing patients to unnecessary treatments. Case report: Patient is an otherwise healthy 30-year-old patient without past medical history; after vigorous physical activity, a Bochdalek hernia was discovered and successfully treated; on follow-ups, he is doing well without signs of recurrence. Conclusions: In adults, Bochdalek hernia is an uncommon form of diaphragmatic hernia. As most cases are asymptomatic, a high index of suspicion is needed since diagnosis is challenging. Modern surgical techniques can improve patient recovery and short hospital stay with minimal morbidity or mortality.
