Differential Diagnosis for 82-year-old with Body Aches, Back Pain, and Eye Pain

Single Most Likely Diagnosis

  • Giant Cell Arteritis (GCA): This condition is a common cause of body aches, back pain, and eye pain in elderly patients. The intermittent nature of symptoms, with some days being fine and others severe, is also consistent with GCA. The age of the patient and the duration of symptoms (3 weeks) further support this diagnosis.

Other Likely Diagnoses

  • Polymyalgia Rheumatica (PMR): Similar to GCA, PMR is an inflammatory condition that causes muscle pain and stiffness, particularly in the shoulders and hips. It is common in older adults and can cause intermittent symptoms.
  • Osteoarthritis: This is a common condition in elderly patients, causing joint pain and stiffness, which could explain the body aches and back pain.
  • Fibromyalgia: A chronic condition characterized by widespread muscle pain, fatigue, and tender points, which could be considered given the patient's symptoms.

Do Not Miss Diagnoses

  • Multiple Myeloma: A type of blood cancer that can cause bone pain, fatigue, and vision problems due to hypercalcemia. Although less likely, it is crucial to rule out due to its severity and potential for treatment.
  • Endocarditis: An infection of the heart valves, which can cause systemic symptoms such as body aches, fever, and eye pain (e.g., Roth spots). It is essential to consider, especially if there are any signs of infection or a new heart murmur.
  • Temporal Arteritis with impending optic neuritis: A variant of GCA that specifically affects the optic nerve, leading to severe and sudden vision loss. Prompt recognition and treatment are critical to prevent blindness.

Rare Diagnoses

  • Relapsing Polychondritis: A rare autoimmune disorder that can cause inflammation in various parts of the body, including the eyes, joints, and cartilage.
  • Sarcoidosis: A condition characterized by the growth of granulomas in various organs, including the lungs, skin, and eyes, which could potentially cause the patient's symptoms.
  • Vasculitis (e.g., Wegener's granulomatosis): A group of rare diseases characterized by inflammation of blood vessels, which can cause a wide range of symptoms, including body aches, eye pain, and respiratory issues.
