Sporadic actinomycosis of the hip complicated by Central Nervous System infection.
J Pak Med Assoc Jan ;67(4):637-40.

Actinomycosis is caused by the Gram positive filamentous Actinomyces bacterial species that are normal commensals of the oral cavity. Due to their low virulence, disease is rare in the immune competent patient. Although it may afflict any system in the body, involvement of the musculoskeletal system is uncommon. Here in, we describe the case of a 60 year old lady presenting with low grade fever, left hip pain and drowsiness. She was diagnosed as left hip actinomycosis on Computed tomogram (CT) guided biopsy and histopathological analysis of infiltrative lesions identified on Magnetic Resonance Imaging (MRI). She also had meningitis diagnosed on cerebrospinal fluid analysis which improved with treatment of actinomycosis. Actinomycosis of the hip is rare, and occurs in the presence of described predisposing factors. To the best of our knowledge, this is the first case of sporadic actinomycosis of the hip complicated by meningitis in an immune competent individual.
