Spondylodiscitis rarely coexists with endocarditis (around 5% of patients with endocarditis). Furthermore, viridans streptococci are not common pathogens of spondylodiscitis and finally the combination of spondylodiscitis and right – sided endocarditis due to viridans streptococci is rare. We present a case of right-sided native valve endocarditis due to Streptococcus mutans presenting as cervical and lumbar spondylodiscitis in a patient with obstructive cardiomyopathy.

A 52 year – old man with a history of hypertrophic obstructive cardiomyopathy was admitted with fever and back pain of ten days duration, followed by torticollis. He had undergone dental therapy some weeks before symptom appearance, due to bad oral hygiene, without receiving any chemoprophylaxis. Magnetic resonance imaging revealed L4-L5 and C4-C5 spondylodiscitides. Four blood cultures drawn were all positive for Streptococcus mutans, while fine needle aspiration of the lumbar lesion was unsuccessful. Transesophageal echocardiogram revealed tricuspid and possible pulmonary valve vegetations.

The patient was treated with ceftriaxone plus gentamicin for 2 weeks and then ceftriaxone only, for a total of 3 months. He had an uneventful recovery and was referred for cardiosurgical consultation.

Physicians managing cases of spondylodiscitides should bear in mind to rule out endocarditis, especially in cases with underlying cardiopathy. The possibility of coexistence is even greater when there is sustained bacteremia and the pathogen isolated from blood cultures is a common pathogen for endocarditis.
