CRP and actinomycosis: Routine blood investigations are nonspecific and may show anemia, mild leukocytosis, and elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Imaging in early stages may show nonspecific inflammatory changes with abscess formation but no lymphadenopathy. At later stages, it may demonstrate tissue infiltration mimicking malignancy, with sinus formation, which, although characteristic, is not specific to actinomycosis [2].
