Pseudotumor Cerebri Symptoms and Clinical Patterns
Primary Symptoms
- The American College of Radiology and Journal of Neurology, Neurosurgery and Psychiatry suggest that headache is the most frequent symptom, typically diffuse and progressively more severe over days to weeks, present in nearly 90% of patients 1, 2
- Visual disturbances, including transient visual obscurations, are common, with the Journal of Neurology, Neurosurgery and Psychiatry recommending monitoring for these symptoms 2
- Pulsatile tinnitus is a symptom, characterized by a whooshing sound in the ears, as noted by the Journal of Neurology, Neurosurgery and Psychiatry 2
- Diplopia, typically horizontal, often due to sixth nerve palsy, is a symptom, according to the Journal of Neurology, Neurosurgery and Psychiatry 2
Secondary Symptoms
- Dizziness, neck pain, back pain, cognitive disturbances, and radicular pain are secondary symptoms, as reported by the Journal of Neurology, Neurosurgery and Psychiatry 2
Clinical Patterns Based on Venous Involvement
- Superior sagittal sinus involvement may lead to headache, increased intracranial pressure, papilledema, and sometimes motor deficits with seizures, as described by Stroke 1
- Lateral sinus thromboses may present with pain in the ear or mastoid region along with headache, according to Stroke 1
- Deep cerebral venous system thrombosis can lead to thalamic or basal ganglial infarction with rapid neurological deterioration, as noted by Stroke 1
Important Clinical Distinctions
- Pseudotumor cerebri predominantly affects overweight females of childbearing age, but can also occur in obese males and prepubertal thin children, with an increasing incidence parallel to the obesity epidemic, as reported by the Journal of the American College of Radiology 4
- Seizures are frequent, occurring in approximately 40% of patients, according to Stroke 1
- Bilateral brain involvement is not uncommon, particularly with deep venous drainage system involvement, as described by Stroke 1
- Isolated headache without focal neurological findings or papilledema occurs in up to 25% of patients, presenting a significant diagnostic challenge, as noted by Stroke 1
