Dural arteriovenous fistula (DAVF) presents with diverse clinical manifestations and is susceptible to misdiagnosis. Herein, we report a case of a 64-year-old male patient who manifested involuntary tremors in the left limb, epileptic seizures, and cognitive decline. Imaging examinations revealed multiple intracranial calcifications, predominantly located in the right cerebral hemisphere, accompanied by occlusion of the superior sagittal sinus. The diagnosis of DAVF was confirmed via digital subtraction angiography (DSA). The patient's symptoms were complex, involving venous hypertension, impaired calcium metabolism, and abnormal motor cortex activity. This case emphasizes the necessity of considering DAVF in patients with unexplained movement disorders and intracranial calcium deposition, and highlights the critical role of DSA in diagnosis. By clarifying the uncommon manifestations of DAVF, this case provides a clinical reference to enhance clinicians' awareness of this condition and underscores the importance of comprehensive multi-factor evaluation.
