Question 1

i have sarcoidosis and a cat scan revealed black spots in my skull, not the brain.. the doctors tell me thatt its sarcoidosis.?

Accepted Answer

The Drs. can explain: One website says bone involvement in sarcoid has ranged between 1 and 13 percent, with an average of 5 percent. An accurate percentage is difficult to obtain as many skeletal lesions are asymptomatic and screening skeletal surveys are not routinely performed. Lytic lesions are cortical defects in the involving the cortex of the bone. That implies darker spots in the skull may be sarcoidosis.

Question 2

why do i  black spots in my skull. revealed by a cat scan. bone marrow biopsy revealed no cancer?

Accepted Answer

DDx: I see a lot of multiple myeloma, so i think of lytic (punched out) lesions in the skull (calvarium) as myeloma. However other cancers such as squamous cell cancers (head/neck, lung, etc) can produce lytic lesions. Sometimes veins going through bone can produce "holes" that are normal. The differential diangosis (ddx) is broad -- eg http://www.Calvariallesions.Com/index.Html.

Question 3

does a ct scan show if there is abnormal pressure in the skull?

Accepted Answer

Sometimes: Pressure abnormalities in the skull such as non-communicating hydrocephalus or low CSF pressure can sometimes be seen indirectly on a ct of the head (usually when chronic and or severe). However, history and physical examination are often better at letting us know when "pressure abnormalities" are of concern and can sometimes be measured directly when a spinal tap is performed.

Question 4

all labs normal but marrow heterogeneity showed up from ct scan of skull looking for frequent dull headaches. i am a 64 yr old male with no other issu?

Accepted Answer

None: mild heterogeneity without significant dx can be ignored esp. when ur other tests are normal.

Question 5

what are neurologists looking for in a 72  hour eeg.  he saw  three white places in  a ct scan.  to me these  spots looked like the skull.  white.

Accepted Answer

Being thorough: We are in an era of procedures.  The more we look the more we find.  The more we find the more we have to look some more.  The white spots may be small scars.  These may cause abnormal discharges from the brain but a prolonged eeg may be necessary to pick them up.  Have your doctors explain the reasons before consenting to procedures.

Question 6

i have a heavy pulse in the back of my neck near base of the skull along with stiffness  , minor headache ct scan no contrast came out normal.. causes?

Accepted Answer

Not sure.: It is hard to know without examining you and talking with you.  If these symptoms continue, would consider an mri.

Question 7

radiology/neurology. ct scan shows bone, mri shows soft tissue, so therefore can't indentify disease of skull bones. intercrainial means misdiagnosis?

Accepted Answer

Misinformation: These scans can show the bone especially the ct. They are designed to see the brain when done in that area but the bones can be seen and can give indications of disease. The brain is intracranial in location. Depending on what it is one is looking for, ct or MRI with or without contrast can be used to image it.

Question 8

i hit my on the 10th. i was ok until the 12th when i woke up with the back of my skull in pain and quite nauseous. went up the er where the ct scan was ok but said it was a concussion. today is 10 days later and my head is killing me. is this normal?

Accepted Answer

Follow up : No, not normal, but could simply be consistent with a post concussive syndrome.  When you are seen in an emergency room you are typically referred to an on call physician to see quickly in follow up.  This decreases likelihood someone will “bounce back” to the ER.  I would follow up with that physician as soon as possible for evaluation and treatment.

Question 9

do you think my child has a contusion or a concussion? my son is 3 i took him the e.r. today he fell and hit head on our tile floor. it sounded like his skull cracked. when they done the ct scan it showed up normal and they said it was a contusion, and wh

Accepted Answer

A : A concussion is simply traumatic brain injury as the result to a direct or indirect blow to the head. A ct can rule out fracture or bleeding but cannot diagnose a concussion. A contussion is merely the outer swelling/bruising of the skin and head. 
Symptoms of concussion include: altered level of consciousness, headache, nasea/vomiting, etc. 
At this point in time the most important things to rule out are bleed/fracture which the ct did. Now you just need to monitor for improvement.

Question 10

can a brain mri miss a skull abnormality? is it reasonable to ask a doctor for ct scan after receiving a brain mri to rule out skull deformities?

Accepted Answer

: CT is better than MRI for bone structure but it should not miss a skull abnormality. Take care.
