Acute appendicitis presenting as chest pain

Abstract Introduction Abdominal pain is the primary presenting complaint of patients with acute appendicitis. Acute appendicitis presenting as chest pain is extremely rare and according to our search such presentation due to herniation of appendix into thorax through congenital diaphragmatic defect has not yet been reported. Presentation of case We present a case of a 12 year old male child who presented with acute chest pain. ECG was suggestive of ischemic changes. Echocardiogram and cardiac enzymes were within normal limits. Chest X-ray and gastrograffin contrast study confirmed the diagnosis of congenital diaphragmatic hernia. On exploration inflamed appendix was found herniated through the diaphragm along with caecum, ascending colon and transverse colon. Histology confirmed the diagnosis of acute appendicitis. Discussion Acute appendicitis may sometimes have very varied and rare presentation. In late presenting CDH, the most important factor responsible for acute or chronic presentation seems to be the type of herniated viscera. Conclusion This report presents a rare case of late-presenting CDH with herniated appendix along with caecum, ascending colon and transverse colon. Unusual presentation of chest pain was due to an attack of acute appendicitis. Late-presenting CDH is a very intriguing defect with a wide spectrum of clinical manifestations. It should be suspected in cases of unexplained acute or chronic respiratory or gastrointestinal symptoms, and abnormal chest radiographic findings. The prognosis is favorable with correct diagnosis and prompt surgical repair.
