What is abnormal density in the brain parenchyma?

Dense brain tissue: Brain parenchyma density is usually referred to as a result of the findings on a ct scan. Hyperdense material will appear bright such as blood. Hypodense material will appear darker and an example of that might be an old stroke. ...Read more

What do mild atrophic changes in brain parenchyma means?

What do mild atrophic changes in brain parenchyma means?

Depends: Isolated atrophy (with no other findings on the scan) in a young person could be a sign of something serious, like a toxic exposure or inflammatory condition, and is seen in dementia. In much older adult patients this may be an expected (normal) finding. ...Read more

Does every layer of meninges have pain sensations? Cause i know brain parenchyma doesn't have any pain sensations

Generally, no: Of the 3 layers that cover and protect the brain, only the outer, dura mater (or "tough mother") has sensory nervers. The middle, arachnoid layer and closest, pia mater (or "intimate mother") are considered to not have sensory innervation. ...Read more

What does mildly low-lying cerebellar tonsils mean? What does unremarkable unenhanced brain parenchyma mean?

It depends: Everyone's brain "sags" onto the skull base when standing, running, defecating. Any sag more than 5mm may suggest chiari malformation or low pressure headache. Have your doctor ask the radiologist to measure the mm of descent for you, the rest of the report is normal. ...Read more

Took brain mri.multiple t2hypointense lesion in cerebral parenchyma.possibilty of granuloma or brain secondries..my mom hv lung cancer.is it secondary?

Probably neither: Difficult to know without seeing all the MRI sequences. It would be helpful to know if the lesions enhance after Gadolinium contrast and if they "bloom" on susceptibility weighted sequences and if they are calcified or invisible on CT scan. Metastatic disease would be very unlikely in a 30 year old without a known primary cancer. My best guess would be multiple cavernous malformations. ...Read more

What does inhomogeneous parenchyma mean on a thyroid sonogram?

What does inhomogeneous parenchyma mean on a thyroid sonogram?

Possible thyroiditis: The normal thyroid has a uniform rather echogenic echo texture. If the echo texture is lower and heterogeneous, thyroiditis is possible. There are several forms, most often autoimmune. This can cause either increased or decreased thyroid hormone production. You should discuss thyroid blood tests with your doctor. Tsh test can be helpful. Any suspicious nodules should be sampled as well. ...Read more
