Ct head scan results are frontal lobe sulci bilateral prominent. Prominate subarachnold space. Midline lipoma. Anterior interhemispheric fissure promi?

Ct head scan results are frontal lobe sulci bilateral prominent. Prominate subarachnold space. Midline lipoma. Anterior interhemispheric fissure promi?

Atrophy: The midline lipoma probably doesnt warrant any treatment. These are usually incidental findings, but they can be associated with some congenital brain disorders. You basically seem to have less brain in your skull relative to fluid spaces relative to others. Have your doctor review the scan with you. ...Read more

Bone (Definition)

Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more

Ct scan"comminuted fracture is seen within right medial cuniform bone with sliglhty displaced cortical bony fragment laterally" surgery or cast? Why .

Ct scan"comminuted fracture is seen within right medial cuniform bone with sliglhty displaced cortical bony fragment laterally"
surgery or cast? Why .

Orthopedic consult: Displaced cuneiform fractures often require an open reduction and internal fixation with screws. This is due to tarsometarsal joint instability. Additional important considerations include - intra-articular vs extra-articular and plane of the fracture. Isolated cuneiform fractures are rare and more likely to happen in association with metatarsal injuries. You need to consult an orthopedic surgeon! ...Read more

Radiology/neurology. Ct scan shows bone, MRI shows soft tissue, so therefore can't indentify disease of skull bones. Intercrainial means misdiagnosis?

Radiology/neurology. Ct scan shows bone, MRI shows soft tissue, so therefore can't indentify disease of skull bones. Intercrainial means misdiagnosis?

Both are complex: CT and MRI can identify bones and soft tissues of the skull and anatomy of the brain but in different types of detail. Intracranial means inside the skull. ...Read more

What does "extensive supraotic pneumatization of the bilateral temporal bones as anatomic variant" mean?

What does "extensive supraotic pneumatization of the bilateral temporal bones as anatomic variant" mean?

See below: As the skull develops, several areas of bone pneumatize, or fill with air cavities. This is a normal process, but is highly variable from person to person. Some people have much larger sinuses and others very small sinuses. The same is true of the mastoid air cells in the temporal bone. Supraotic just means the air cells extend above the otic capsule, which is a part of the temporal bone. ...Read more

Clivus bone tumor fiber-osseous what are the symptoms ?

Clivus bone tumor fiber-osseous what are the symptoms
?

Clivus bone tumor: “Fibro-osseous”? Do you mean fibrous dysplasia? These tumors are very rare. Symptoms: headache (sometimes severe) near base of back of the skull. Pain made worse by moving the head/neck. Possible visual problems because of weakness of a nerve (cranial nerve #6) that controls eye movement. The eye will cross inward toward the nose. Anyone with these problems should see his/her doctor. ...Read more

Is neuromuscular dentistry effective for TMJ?  MRI shows bone spurs, disc fragments and flattening of the Condyle

Recommendation: Suggest you get referral to Oral Surgeon, as your description raises concerns about extensive degeneration of the joint, and you may require a repair procedure. You may even want two opinions on how to manage. ...Read more

3 yrs lytic bone lesions through axial skeleton -skull. Extramedullary hematopoiesis. New MRI spots on brain-bone marrow expansion. Can this be fatal?

3 yrs lytic bone lesions through axial skeleton -skull. Extramedullary hematopoiesis. New MRI spots on brain-bone marrow expansion. Can this be fatal?

Depends: Bone marrow expansion throughout the skeleton typically signals either that the marrow is i appropriately expanding into these compartment such as in a myeloproliferative disorder or the present regions of marrow production are insufficient to keep up with current body needs. Regardless of the cause this is best answered by hands on evaluation, testing and management by an hematologist. ...Read more

Right lateral ventricle frontal horn compressed,Anterior midline mildly shifted to left,C2 vertebrae bone cyst,right frontal lobe glioma,treatment?

See a surgeon.: It sounds like parts of your brain may be under pressure from the tumor. A good treatment for this is surgery to remove the mass. Speak to a surgeon for more details. ...Read more

What does it mean neck X-ray report. No fractures or subluxation visualized. Cervical spine straightening. No PREVERTEBRAL soft tissue swelling. Open mouth view is limited by overlying bony structures. ?

What does it mean neck X-ray report. No fractures or subluxation visualized. Cervical spine straightening. No PREVERTEBRAL soft tissue swelling. Open mouth view is limited by overlying bony structures. ?

Cervical: Sounds like an entirely normal X-ray. All cervical spines straighten out in cray or MRI done supine. Alternatively could be indication of some cervical muscle spasm causing splinting and thus straightening of the spine. ...Read more

Cspine MRI : 1 :cervical degenerative disease 2 : vague area of marrow hypointensity in the several vertebral bodies of questionable etiology ?

Cspine MRI : 
1 :cervical degenerative disease 
2 : vague area of marrow hypointensity in the several vertebral bodies of questionable etiology ?

Not sure : I am not sure what you are expecting from the above. The diagnosis is listed - cervical degenerative disease. Vague area of marrow hypointensity is a very non-specific finding that i would not worry about provided there are no other findings on the MRI and they don't have a reproduction on the physical exam. ...Read more

Wha does this mean, soft tissue densities within mastoid cells, middle ear cavity and sphenoid sinus and calcific density in brain paren occipital reg?

Wha does this mean, soft tissue densities within mastoid cells, middle ear cavity and sphenoid sinus and calcific density in brain paren occipital reg?

Nonspecific : Soft tissue densities in the normally air filled mastoid, middle ear and sinus cavities indicates there is some type of chronic, long term inflammation in those areas. It could indicate chronic infection, as well. It depends on your clinical condition and how severe those findings are to really give you an idea of what this means to you. The brain finding is not uncommon, discuss with doctor. ...Read more

Does maxilla and sphenoid bone have suture?

Does maxilla and sphenoid bone have suture?

Maxilla and sphenoid: The maxilla and sphenoid are separate bone units of the skull. The squamousal suture can intersect with the sphenoid wing in some people. But technically there is not a true suture between the two bone units. ...Read more

Knee injury. MRI report "PCL Avulsion fracture of tibia (6-7mm displacement) with adjacent tibial bone edema. fibers are intact." is surgery needed?

Knee injury. MRI report  "PCL Avulsion fracture of tibia (6-7mm displacement) with adjacent tibial bone edema. fibers are intact." is surgery needed?

Yes, it should if-: -U expect 2 have a functioning knee 4 the rest of Ur life. It can only separate more, & a simple reduction & fixation will do what U want it 2 do, reunite the fragment 2 the tibia. The image is a tear & requires a major reconstruction if not fixed. U risk the fragment becoming a nonunion. ...Read more

Excruciating pain in scapula, "mass" on mri. Bone spur or bone cancer?

Excruciating pain in scapula, "mass"  on mri. Bone spur or bone cancer?

Sorry to hear: This. A scapula is a very odd bone for a primary tumor, and also odd for something traveled to that bone, but it does no get bone spurs. A "mass" needs to be biopsied. However, it is more likely to be from some other place: lung, breast (w), prostate (m)...My last scapular met came from a kidney primary. ...Read more
