“Superficial Siderosis”, a rare concomitant finding in Spontaneous Intracranial Hypotension

Abstract

Superficial siderosis as a concomitant finding in SIH has not been quite frequent. Superficial siderosis, especially in the posterior fossa, when seen in patients with headaches, is vital to evaluate for spontaneous intracranial hypotension. Subpial hemosoderin deposition in the brain and spinal cord usually occurs as a result of recurrent or persistent haemorrhage into the subarachnoid space, the source of which is not discernible in all cases, in spite of extensive neuroimaging. We report a patient who presented with headache and vomiting, whose neuroimaging findings were indicative of features pointing towards superficial siderosis and SIH. Early identification of superficial siderosis in headaches not only helps us diagnose SIH but also guides clinicians to provide proper treatment, which could avoid complications.
