Differential Diagnosis

Sarcoidosis has many differentials, which can be classified depending on the organ involved.[1]

Lung[2]

1.Tuberculosis 2.Atypical Mycobacteriosis 3.Cryptococcosis 4.Aspergillosis 5.Aspiration of foriegn materials 6.Blastomycosis 7.Pneumocystitis carinii 8.Pneumoconiosis 9.Drug reactions 10.Hypersensitivity pneumonitis 11.Drug reactions12..Histoplasmosis 13.Chronic interstitial pneumonia 14.Necrotizing sarcoid granulomatosis 15.Wegner's granulomatosis

Lymph Node

1.Tuberculosis 2.Atypical Mycobacteriosis 3.Brucellosis 4.GLUS syndrome 5.Cat scratch disease 6.Toxoplasmosis 7.Hodgkin disease 8.Non Hodgkin lymphoma 9.Sarcoid reaction in lymph nodes to carcinoma 10.Kikuchi disease(granulomatous histiocytic necrotizing lymphadenitis)

Differential diagnosis

Causes of

lung cavities

Differentiating Features Differentiating radiological findings Diagnosis

confirmation

  • CXR and CT demonstrates cavities in the upper lobe of the lung
  • Sputum smear positive for acid-fast bacilli and nucleic acid amplification tests (NAAT) is used on sputum or any sterile fluid for rapid diagnosis and is positive for mycobacteria.
  • Any age group
  • Acute, fulminant life threating complication of prior infection
  • >100.4F fever, with hemodynamic instability
  • Worsening pneumonia-like symptoms
  • CBC is positive for causative organism
  • Children and elderly are at risk
  • Empyema appears lenticular in shape and has a thin wall with smooth luminal margins
  • Pulmonary nodules with cavities and infiltrates are a frequent manifestation on CXR
  • Elderly females of 40-50 age group
  • Manifestation of rheumatoid arthritis
  • Presents with other systemic symptoms including symmetric arthritis of the small joints of the hands and feet with morning stiffness are common manifestations.
  • Pulmonary nodules with cavitation are located in the upper lobe (Caplan syndrome) on Xray.
  • On CXR bilateral adenopathy and coarse reticular opacities are seen.
  • CT of the chest demonstrates extensive hilar and mediastinal adenopathy
  • Additional findings on CT include fibrosis (honeycomb, linear, or associated with bronchial distortion), pleural thickening, and ground-glass opacities.[9]
  • Common appearance on CT is patchy consolidation,often accompanied by ground-glass opacities and nodules.[13]
  • Exclusively afflicts smokers, with a peak age of onset of between 20 and 40 years.
  • Clinical presentation varies, but symptoms generally include months of dry cough, fever, night sweats and weight loss.
  • Skin is involved in 80% of the cases, scaly erythematous rash is typical.
  • Thin-walled cystic cavities are the usual radiographic manifestation, observed in over 50% of patients by either CXR or CT scans.[15]
  • Biopsy of the lung

Sarcoidosis must be differentiated from other diseases that cause bone pain, edema, and erythema.

Disease Findings
Soft tissue infection
(Commonly cellulitis) 		History of skin warmness, swelling and erythema. Bone probing is the definite way to differentiate them.[16][17]
Osteonecrosis
(Avascular necrosis of bone) 		Previous history of trauma, radiation, use of steroids or biphosphonates are suggestive to differentiate osteonecrosis from ostemyelitis.[18][19]
MRI is diagnostic.[20][21]
Charcot joint Patients with Charcot joint commonly develop skin ulcerations that can in turn lead to secondary osteomyelitis.
Contrast-enhanced MRI may be diagnostically useful if it shows a sinus tract, replacement of soft tissue fat, a fluid collection, or extensive marrow abnormalities. Bone biopsy is the definitive diagnostic modality.[22]
Bone tumors May present with local pain and radiographic changes consistent with osteomyelitis.
Tumors most likely to mimic osteomyelitis are osteoid osteomas and chondroblastomas that produce small, round, radiolucent lesions on radiographs.[23]
Gout Gout presents with joint pain and swelling. Joint aspiration and crystals in synovial fluid is diagnostic for gout.[24]
SAPHO syndrome
(Synovitis, acne, pustulosis, hyperostosis, and osteitis) 		SAPHO syndrome consists of a wide spectrum of neutrophilic dermatosis associated with aseptic osteoarticular lesions.
It can mimic osteomyelitis in patients who lack the characteristic findings of pustulosis and synovitis.
The diagnosis is established via clinical manifestations; bone culture is sterile in the setting of osteitis.
Sarcoidosis It involves most frequently the pulmonary parenchyma and mediastinal lymph nodes, but any organ system can be affected.
Bone involvement is often bilateral and bones commonly affected include the middle and distal phalanges (producing “sausage finger”), wrist, skull, vertebral column, and long bones.
Langerhans' cell histiocytosis The disease usually manifests in the skeleton and solitary bone lesions are encountered twice as often as multiple bone lesions.
The tumours can develop in any bone, but most commonly originate in the skull and jaw, followed by vertebral bodies, ribs, pelvis, and long bones.[25]
