A patient arrives at the emergency department with abdominal pain, nausea, and vomiting. A physical examination reveals acute pain at the McBurney point. A CT scan confirms the diagnosis, and surgery is immediately scheduled to prevent peritonitis. Based on this information, which diagnosis is described?
A.
Inguinal hernia
B.
Gastroenteritis
C.
Cholelithiasis
D.
Acute appendicitis
The correct answer and Explanation is :
The correct answer is D. Acute appendicitis.
Acute appendicitis is the inflammation of the appendix, a small, finger-like pouch attached to the large intestine. It is a common cause of acute abdominal pain and often requires urgent surgical intervention to prevent complications like rupture and peritonitis (infection of the abdominal lining).
Symptoms
The patient’s symptoms of abdominal pain, nausea, and vomiting are typical of acute appendicitis. The pain initially begins near the umbilicus (belly button) and, over time, migrates to the right lower quadrant of the abdomen. The hallmark sign of acute appendicitis is localized tenderness at McBurney’s point, which is located one-third of the distance from the anterior superior iliac spine to the umbilicus. This point is a key area where pain manifests in appendicitis, indicating inflammation or impending rupture of the appendix.
Diagnosis
A combination of clinical examination and imaging is used to diagnose acute appendicitis. In this scenario, the physical examination reveals acute pain at McBurney’s point, which strongly suggests appendicitis. A CT scan, which provides detailed images of the abdominal organs, confirms the diagnosis by visualizing the inflamed appendix.
Surgical Intervention
Surgery, typically an appendectomy, is scheduled immediately to remove the inflamed appendix. This is crucial because if the appendix ruptures, it can release infectious material into the abdomen, leading to peritonitis, a life-threatening condition requiring emergency treatment.
Differential Diagnoses
- Inguinal hernia (A) is characterized by a bulge in the groin or abdominal area.
- Gastroenteritis (B) presents with diarrhea and generalized abdominal cramping.
- Cholelithiasis (C) involves gallstones and is associated with upper-right quadrant pain.
Given the specific symptomatology and McBurney point tenderness, the most accurate diagnosis is acute appendicitis.
