Formulating an accurate differential diagnosis for acute monoarticular or oligoarticular joint pain requires distinguishing among competing etiologies based on specific clinical findings. Match each patient's clinical presentation with the most likely diagnosis on the differential.
- A 45-year-old male presents with acute, excruciating pain, swelling, and erythema of the right first metatarsophalangeal joint after a weekend of heavy alcohol consumption.Gout
- A 26-year-old male develops an acutely swollen left knee, mild conjunctival injection, and dysuria two weeks after an unprotected sexual encounter.Reactive arthritis
- A 62-year-old female with poorly controlled diabetes mellitus presents with a highly inflamed right knee, high fever, and severely restricted passive and active range of motion.Septic arthritis
- A 71-year-old male with a known history of hemochromatosis presents with acute knee swelling; joint aspiration reveals positively birefringent, rhomboid-shaped crystals.Calcium pyrophosphate deposition disease
Cevap
The correct matches align each classic arthritis presentation with its definitive diagnosis: the first MTP pain post-alcohol is Gout; the post-infectious triad is Reactive arthritis; the highly febrile, immobile joint in a diabetic is Septic arthritis; and the rhomboid crystals identify Calcium pyrophosphate deposition disease.
Each diagnosis is established by recognizing its highly specific, pathognomonic clinical pattern from the broad differential of acute joint pain. Gout is identified by typical podagra triggers; reactive arthritis by its post-infectious triad; septic arthritis by systemic toxicity and severe localized immobility; and CPPD by distinct crystal morphology.

Formulating a differential diagnosis for acute monoarticular or oligoarticular arthritis relies on distinguishing key clinical features such as specific joint involvement, antecedent triggers, systemic symptoms, and specific synovial fluid characteristics.
