Difficulty: EasyRheumatology and Immunology

Pair each patient's key clinical findings with the most appropriate rheumatologic or vasculitic diagnosis.

  • An elderly female patient reporting recent-onset unilateral headache, pain when chewing food, and episodes of transient vision loss.Giant cell arteritis
  • A young adult male complaining of chronic lower back stiffness that is worse upon awakening but improves after his morning jog, accompanied by a recent episode of anterior uveitis.Ankylosing spondylitis
  • A middle-aged female patient presenting with severe xerophthalmia, xerostomia, and visibly enlarged parotid glands.Sjögren syndrome
  • A middle-aged male presenting with sudden, excruciating pain, erythema, and swelling localized entirely to the first metatarsophalangeal joint.Gout

Answer

Headache and jaw claudication pairs with Giant cell arteritis; inflammatory back pain and uveitis pairs with Ankylosing spondylitis; sicca symptoms and parotid enlargement pairs with Sjögren syndrome; acute first MTP arthritis pairs with Gout.
Each patient vignette describes classic, pathognomonic features of common rheumatologic and vasculitic conditions, testing the fundamental ability to recognize these hallmark presentations.

Step-by-Step Solution

1
Evaluate the first vignette for classic vasculitis symptoms.
The symptoms align with temporal arteritis, which requires urgent recognition to prevent irreversible vision loss.
Identifying the classic triad in elderly patients points directly to the diagnosis.
2
Analyze the second vignette for characteristics of back pain.
The pain improves with exercise and is associated with extra-articular manifestations (uveitis), indicating an inflammatory etiology.
Differentiating inflammatory from mechanical back pain is the key step in diagnosing axial spondyloarthritis.
3
Assess the third vignette for characteristic exocrine gland dysfunction.
The dry eyes, dry mouth, and parotid swelling are identified as classic sicca syndrome.
These findings directly map to the primary clinical criteria for the condition.
4
Examine the fourth vignette for crystal arthropathy signs.
The severe, acute onset of pain in the great toe (podagra) is identified.
Podagra is the most common and specific initial presentation of this crystal arthropathy.
