Omental Infarction (OI) is a rare condition that can mimic common causes of acute abdominal pain, primarily affecting individuals aged 40 to 50, with a male predominance. Imaging techniques like ultrasound and computed tomography aid in diagnosis. Treatment options range from conservative management to surgery, depending on severity and complications. OI often leads to right-sided abdominal pain in 90% of cases, with histological features including focal necrosis and fibroblastic reactions. 

Acute appendicitis is a common cause of acute abdominal conditions, especially in children and adolescents. Having a patient simultaneously presenting with acute appendicitis and omental infarction is extremely rare, with only three cases reported in the literature to date to our knowledge.

We present the case of a 32-year-old male, a heavy smoker, who presented with epigastric pain and vomiting. Initial clinical suspicion was a perforated ulcer, but imaging revealed swollen appendicitis with adjacent fat stranding and evidence of epiploic infarction near the stomach. 

Laparoscopic surgery confirmed the diagnosis of acute appendicitis, with an appendectomy performed and identification of the infarcted omentum, which was preserved. After the operation, the patient had a successful recovery and was discharged on the second postoperative day.

This case firstly emphasizes the rarity of the association between acute appendicitis and omental infarction in the same patient and underscores the importance of considering Omental Infarction (OI) in the differential diagnosis of acute abdominal pain. Imaging plays a crucial role in accurate diagnosis, and a high degree of suspicion and prompt diagnosis are crucial for optimal patient outcomes.
