Pseudotumour cerebri is a disease presented with the signs and symptoms of increased intracranial pressure in the absence of any intracranial tumour, hydrocephalus or anatomic abnormalities. It is an ocular emergency because it causes rapid and irreversible vision loss. If there is no cause, it is called idiopathic intracranial hypertension. Besides idiopathic cases, the most common cause is cerebral venous sinus thrombosis. The aim of the present study is to evaluate the aetiology in our patients with pseudotumour cerebri secondary to systemic diseases.
Haseki Training and Research Hospital
aetiological factors in 12 cases with pseudotumour cerebri due to systemic diseases were evaluated.
Cranial magnetic resonance imaging was normal in all patients, but cerebral magnetic resonance venography demonstrated cerebral venous sinus thrombosis .With lumbar puncture, composition of cerebrospinal fluid was normal but cerebrospinal fluid pressure was above 300 mmH2O. The aetiological causes of pseudotumour cerebri were recorded as Behcet's disease in three cases, polycytheamia vera in two cases, iron-deficiency anaemia in one case, subacute sclerosing panencephalitis in one case, acute lymphoblastic leukemia in one case, nephrotic syndrome in one case, neurobrucellosis in one case, essential thrombocytosis in one case and POEMS syndrome in one case.
Systemic diseases can cause cerebral venous sinus thrombosis which is an important cause of pseudotumour cerebri. It is important to think about the probability of papilledema and pseudotumour cerebri when evaluating the patients wıth these systemic diseases, be alert and want cerebral magnetic resonance venography immediately in any case of suspicion.
