Simultaneous Multifocal Intracranial Haemorrhages Associated with Staphylococcus Aureus Endocarditis: A Plausible Role for Diclofenac Administration.

INTRODUCTION

Intracranial haemorrhage may complicate infective endocarditis, caused by ruptured mycotic aneurysms or haemorrhagic transformation of brain septic emboli. The risk of intracranial bleeding may increase with the use of non-steroidal anti-inflammatory agent (NSAIDs).

CASE DESCRIPTION

We report on a 53-year-old male patient with a past history of intravenous drug abuse, who was treated with diclofenac (75 mg IM) for a few hours of preceding fever and arthralgia. Seven hours later he was hospitalised with impaired consciousness and hemiparesis. Evaluation revealed multiple intracranial haemorrhages, at least one originating from a mycotic aneurysm. Repeated blood cultures grew methicillin-resistant (MRSA), and echocardiography revealed a vegetation on the mitral valve, establishing the diagnosis of bacterial endocarditis.

CONCLUSION

The abrupt simultaneous multifocal intracranial bleeds shortly following the administration of NSAIDs for a few hours of febrile disease, one clearly originating from a mycotic aneurism, are exceptional. This raises a possibility of a role for diclofenac the intracranial bleeding diathesis in this unique clinical presentation. Intracranial haemorrhage in the set-up of undiagnosed infective endocarditis (IE) might be added to the long list of potential adverse outcomes of NSAID administration, and the possibility of IE should be considered before their administration for febrile disease of undetermined cause.
