SBE is a masquerader of numerous disease processes due to the myriad of nonspecific symptoms and signs. Other inflammatory processes, such as vasculitis, atheroembolism, and metastatic malignancy, may be associated with signs and symptoms (eg, fever, weight loss, back pain, and anorexia), as well as laboratory findings (eg, anemia, leukocytosis, and an elevated sedimentation rate), all of which can occur with SBE. Obstructive sleep apnea typically presents with snoring, daytime somnolence, and, occasionally, evidence of pulmonary hypertension or cor pulmonale but is not associated with systemic inflammation.
