Differential Diagnosis for Left Rib, Left Flank, and Left Lower Abdominal Pain
Single Most Likely Diagnosis
- Musculoskeletal strain: Given the location of the pain (left rib, left flank, and left lower abdominal area) and the mechanism of injury (fall from 3 feet), a musculoskeletal strain is the most plausible diagnosis. This type of injury can occur from direct trauma or indirect strain from the fall.
Other Likely Diagnoses
- Rib fracture: A fall from 3 feet can generate enough force to cause a rib fracture, especially if the patient landed directly on their side. The pain from a rib fracture can radiate to the flank and abdominal area.
- Kidney contusion or laceration: The left flank pain could indicate a kidney injury, which is possible given the mechanism of injury. The pain might also be referred to the lower abdominal area.
- Spleen injury: Although less common without a history of severe abdominal trauma, a spleen injury (laceration or rupture) could present with left upper quadrant pain radiating to the left flank and lower abdomen.
Do Not Miss Diagnoses
- Pneumothorax: A traumatic pneumothorax could occur from a rib fracture puncturing the lung. This is a life-threatening condition that requires immediate attention.
- Hemorrhage (internal bleeding): Significant internal bleeding from any of the organs in the abdominal cavity (such as the spleen, liver, or kidneys) or from major blood vessels could lead to shock and death if not promptly diagnosed and treated.
- Ureteral injury: Though rare, an injury to the ureter could occur from the trauma and might present with flank pain. This condition requires urgent surgical intervention to prevent long-term damage.
Rare Diagnoses
- Diaphragmatic rupture: This is a rare but serious condition where the diaphragm is torn, which can allow abdominal organs to herniate into the thoracic cavity. It might present with severe pain and respiratory distress.
- Pancreatic injury: Direct trauma to the pancreas can cause pancreatitis or a pancreatic rupture, which would be indicated by severe abdominal pain, possibly radiating to the back.
- Adrenal gland injury: Though extremely rare, an injury to the adrenal gland could occur from severe trauma and might present with flank pain and potentially life-threatening hormonal imbalances.
