Since the advent of modern antibiotic therapy and active surgical treatment of bacterial endocarditis, septic embolization of the systemic circulation is rarely seen. An unusual presentation of a mycotic aneurysm with gastrointestinal haemorrhage in a patient with non-Hodgkin's lymphoma and aortic valvular endocarditis which had been managed by aortic valve replacement six weeks before the haemorrhage occurred is reported.

We report a case of endocarditis caused by a ciprofloxacin-resistant strain of Serratia marcescens in a 50-year-old female neutropenic patient with non-Hodgkin's lymphoma which occurred while receiving ciprofloxacin prophylaxis. She made poor progress on first line therapy with azlocillin and gentamicin by bolus injection t.d.s. The infection was finally eliminated by a regimen of continuous infusion of azlocillin and once daily gentamicin.

The diagnosis of nonbacterial thrombotic endocarditis is rarely made during life. We describe a patient with non-Hodgkin's lymphoma with evidence of systemic embolism in which transesophageal echocardiography was useful in establishing the diagnosis. The clinical and echocardiographic features of nonbacterial thrombotic endocarditis should be remembered when a valvular mass is seen on echocardiography.

The risk factors, microbial patterns, and prognosis of intramedullary abscess have varied with time. The development of an intramedullary abscess of the spinal cord (IASC) constitutes an exceptional complication of infective endocarditis (IE) in the post-antibiotic era. We present a case of cervical IASC by viridans group Streptococcus in a patient with mitral valve IE. We hypothesize that previous cervical radiotherapy for non-Hodgkin's lymphoma favoured the occurrence of this uncommon entity. This physiopathologic mechanism has not been previously reported.

The diagnosis of nonbacterial thrombotic endocarditis (NTBE) is rarely made during life. This report describes a child who had high-grade non-Hodgkin's lymphoma with NTBE and multiple systemic embolism. The transthoracic echocardiographic findings of mitral valve leaflet vegetations and progressive regurgitation led to surgical resection of the vegetations. A high index of suspicion is needed when a clinician is faced with a patient who has malignancy, systemic embolic phenomena, and persistent negative blood cultures.

Micrococcus species are typically considered contaminants from skin and mucous membranes. However, especially in severely immunocompromised patients, a blood culture with Micrococcus could be the cause of a significant infection. We report a 65-year-old female with non-Hodgkin's lymphoma who developed native valve infective endocarditis due to Micrococcus luteus. There is no defined therapeutic regimen for infective endocarditis due to Micrococcus luteus; however, our patient was successfully treated for six weeks with vancomycin and rifampin. To our knowledge, there is only one other case report of native valve endocarditis due to Micrococcus luteus.

BACKGROUND Following transvenous lead extraction (TLE) for infective endocarditis, a fibrinous remnant, or "ghost", that previously encapsulated the lead may remain. The main aim of this case report was to highlight the importance of identification of ghosts, their negative implications, and the importance of close monitoring. CASE REPORT A 72-year-old male with a history of heart failure with non-ischemic cardiomyopathy and remote cardiac resynchronization therapy defibrillator (CRT-D) placement as well as atrioventricular node ablation for atrial fibrillation presented following a mechanical fall. An initial evaluation revealed methicillin-resistant Staphylococcus aureus bacteremia; the suspected nidus was an indwelling chemotherapy port for non-Hodgkin's lymphoma. Echocardiography demonstrated vegetations on the aortic and mitral valves, and the right atrial device lead concerning for infective endocarditis. After TLE, a temporary transvenous wire was placed. Definitive pacing was then achieved by a Micra leadless pacemaker (LP). We opted with LP technology via the Micra device with plan for subcutaneous implantable cardioverter defibrillator (SICD) implantation to mitigate the risk of infection recurrence. After completion of 6 weeks of antibiotics, a pre-SICD transesophageal echocardiogram identified a 1.3 cm mobile echo-dense "ghost" in the right atrium. SICD was implanted as planned. Following expert consensus, no specific therapy was implemented when the ghost was identified. At 3 months, echocardiography revealed the absence of the ghost. At 1-year follow-up, no infection recurrence was noted. CONCLUSIONS The presence of ghosts after transvenous lead extraction is associated with poor outcome and infection recurrence thus requiring diligent monitoring and serial echocardiography as optimal management is yet to be defined.
