Idiopathic intracranial hypertension without headache: A case report and literature review.

This study reports the case of a 23-year-old man with idiopathic intracranial hypertension (IIH) who presented with blurred vision and diplopia, without accompanying headache. Although headache is the most common symptom associated with IIH, occasionally, it may not be observed clinically. This situation is more frequently observed in males, young adults, children, and in patients with low body mass index. This case highlights a crucial aspect; patients who present with serious visual symptoms without headache must be treated aggressively because vision loss will develop rapidly.
