Bochdalek hernia, a rare congenital diaphragmatic anomaly, has garnered substantial attention due to its intricate pathophysiological underpinnings and multifaceted clinical implications. This article endeavors to provide an exhaustive analysis of Bochdalek hernia, encompassing its embryological origins, intricate pathophysiology involving the posterolateral diaphragmatic defect, and the subsequent herniation of abdominal contents into the thoracic cavity. A meticulous exploration of the clinical presentation underscores the considerable variation in symptomatology, ranging from asymptomatic cases incidentally detected on imaging, to severe respiratory distress and life-threatening consequences in neonates. The diagnostic armamentarium, including radiographic, ultrasonographic, and tomographic modalities, is scrutinized with a focus on their respective sensitivities and specificities in discerning this anatomical aberration. In light of contemporary advancements, the article elucidates the expanding role of three-dimensional reconstructions and minimally invasive techniques in achieving accurate diagnosis and surgical planning. Furthermore, the management landscape is delineated, encompassing conservative approaches for asymptomatic cases, urgent surgical interventions for acute presentations, and the nuanced perioperative considerations for neonates and pediatric patients. A comprehensive overview of surgical techniques, ranging from traditional open procedures to the evolving realm of robotic-assisted and laparoscopic repairs, is provided, with emphasis on individualized strategies tailored to patient-specific factors. In summation, this article offers a comprehensive and sophisticated exploration of Bochdalek hernia, amalgamating embryology, pathophysiology, clinical presentation, diagnostic modalities, and contemporary management paradigms. It is envisaged that this review will serve as a valuable resource for medical practitioners, surgeons, and researchers, fostering an enriched understanding of this intricate condition and facilitating informed decision-making in its management.
