Hi, thank you for your reply.
My son hasn't had an MRI since 18 mths. He's 3 1/2 now. He did have a CT without contrast in December due to recurring waking headaches. It was normal.
I noticed in photos that he seems like his head has grown larger leaving a slight dent above his eyebrowns that seem to hold a shadow in the photos. When he was younger his forehead altho frontal bossing, seemed rounded and these dents that cause shadows in the photos were not obvious.
Would you think that with a normal CT, an MRI would still be warranted?
Is it normal for frontal bossing to change shape over time from rounded to two somewhat distint lumps on each side of forehead, leaving slight dents above the eyes that show as shadows in photos?
thanks for your advice

Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
Head circumference is measured around the widest part of the skull. When it becomes enlarged, we call this macrocephaly. Causes are many and should be evaluated. They include metabolic causes such as Canavan’s, Hurler’s, and Alexander’s syndromes. Others include cerebrospinal fluid flow changes that can occur from obstruction or lack of resorption. These may be secondary to infections, trauma, congenital malformations, etc. Lastly, any disease that increases intracranial pressure can also cause head growth changes. These can include tumors, bleeds, etc. Overall, symptoms may include changes in mentation, irritability, vomiting, eye movement abnormalities, etc. You should have your son evaluated with some form of neuroimaging such as an MRI if not already done. Was this performed while he was admitted to the hospital?
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
