它是腦部有tumor的一種非典型表現 它包含明顯腦壓上升且CSF檢查不正常

Pseudotumor cerebri, also known as idiopathic intracranial hypertension (IIH) is a disorder of unknown etiology. It affects predominantly obese women of childbearing age.¹ The primary problem is chronically elevated intracranial pressure (ICP), and the most important neurologic manifestation is papilledema, which may lead to progressive optic atrophy and blindness.¹

but in infant, since the skull suture not fused yet, you cant find typical signs of increase in ICP as in adult!
