Differential Diagnosis for Left Lower Quadrant Pain in Female

Single Most Likely Diagnosis

  • Diverticulitis: This is a common cause of left lower quadrant pain in females, especially in those over 40 years old. The pain is usually constant and can be accompanied by changes in bowel habits, fever, and nausea.

Other Likely Diagnoses

  • Ovarian Cyst: Ovarian cysts can cause left lower quadrant pain due to rupture, torsion, or hemorrhage. The pain is often sharp and can be accompanied by vaginal bleeding or urinary symptoms.
  • Ectopic Pregnancy: Although more common on the right side, ectopic pregnancies can occur on the left side and cause severe, sharp pain. This diagnosis should be considered in females of childbearing age with a missed period or positive pregnancy test.
  • Constipation: Constipation is a common cause of left lower quadrant pain, especially if the pain is accompanied by bloating, straining during bowel movements, or hard stools.
  • Irritable Bowel Syndrome (IBS): IBS can cause left lower quadrant pain, bloating, and changes in bowel habits. The pain is often crampy and can be relieved by bowel movements.

Do Not Miss Diagnoses

  • Ruptured Ovarian Cyst: A ruptured ovarian cyst can cause severe, life-threatening bleeding and should be considered in females with severe pain, vaginal bleeding, and signs of shock.
  • Ectopic Pregnancy Rupture: A ruptured ectopic pregnancy is a medical emergency that requires immediate attention. Females with severe pain, vaginal bleeding, and signs of shock should be evaluated for this condition.
  • Diverticular Bleeding: Diverticular bleeding can cause severe, life-threatening bleeding and should be considered in females with severe pain, bloody stools, and signs of shock.
  • Intestinal Obstruction: Intestinal obstruction can cause severe, life-threatening complications and should be considered in females with severe pain, vomiting, and abdominal distension.

Rare Diagnoses

  • Endometriosis: Endometriosis can cause left lower quadrant pain, especially during menstruation. The pain is often sharp and can be accompanied by heavy menstrual bleeding or infertility.
  • Inflammatory Bowel Disease (IBD): IBD, such as Crohn's disease or ulcerative colitis, can cause left lower quadrant pain, diarrhea, and weight loss.
  • Ureteral Stone: A ureteral stone can cause severe, sharp pain that radiates to the groin. The pain is often accompanied by nausea, vomiting, and urinary frequency.
  • Lymphoma: Lymphoma can cause left lower quadrant pain, weight loss, and fatigue. The pain is often constant and can be accompanied by night sweats or fever.
