My husband has frequent spells of lightheadedness, some severe, they are accompanied by a pain and a feeling of hearbeat at C5-6.  CAT scans and MRI with and without contrast of head and neck show hygromas  on the L and R anterior part of the brain.  Husband feels it all is coming from the back of the neck.  Please help.
Hi, Aroma means the accumulation of cerebrospinal fluid under the subdural space. Symptoms being light-headed less, weak less etc. Some are minimal and don't need treatment, except symptomatic. I advise you to consult a neurosurgeon for diagnosis and treatment. Thank you.
