Spontaneous bilateral subdural hematoma in a patient with a prosthetic valve and association with plasmodium vivax malaria: A rare case report.

Introduction and importance: Bilateral subdural hematoma (SDH) is a very rare condition which can occur without any apparent etiology. It's characterized by a lower frequency of focal neurological impairments, which could delay the diagnosis and postpone treatment. The reported incidence of an acute spontaneous subdural hematoma (SSH) varies between 2% and 6.7% of all acute SDH. SDH following Plasmodium vivax (P. vivax) infection are uncommon to our knowledge, only two cases of SDH linked with P. vivax infection have been documented in the literature. Case presentation: We describe a case of a 31-year-old male with a history of mitral mechanical valve replacement on anti-coagulant presented with spontaneous bilateral subdural hematoma in the presence of malaria. The patient had a limited vague symptom, which delayed a prompt diagnosis of his disease. Clinical discussion: Spontaneous subdural hematoma has only a few documented cases. Hypertension, infections, vascular malformations, ruptured aneurysms, thrombocytopenia caused by hematological and oncological illnesses, acquired or inherited types of coagulopathies, and drug abuse are all risk factors. Also, SDH has been documented in the literature as a consequence of Plasmodium infection. In addition to that this patient was on anti-epileptic medicines which might potentiate vitamin K antagonists. Numerous factors were thought to have contributed to this significant bleeding. Conclusion: Patients on anticoagulants who exhibit nebulous symptoms, including a mild headache, should be subjected to a thorough history and examination. And any factor delaying an accurate diagnosis should be eliminated. This will complement the patient's plan and management.
