Hello doctor, 4 years old had an MRI for hearing loss. The report impression: Left mastoid and middle ear effusion. But my question is they listed left frontal region arachnoid cyst with adjacent mass effect. They are getting another MRI ordered and an appointment with a neurologist. I have looked at the symptoms, she has none, except dizziness when going in circles, she does not like it. Unknown from fluid in ear or cyst. Can you please give me some information of what this is? I cannot sleep.
Hello. I read carefully your question and would explain that the dizziness is not related to the arachnoid cyst. You should know that arachnoid cysts are usually asymptomatic and they are present since birth. Anyway, sometimes if they grow, they may lead to seizures or motor or sensory deficits. For this reason, it is important consulting with a neurosurgeon. Follow up with brain MRI every year may be needed.
