Doctor insights on: Posterior Fossa Cyst

Share

Cyst (Definition)

A cyst is a structure or mass that consists of a cellular lined sac. It is typically filled with fluid but may be filled with solid material. It can be congenital, traumatic, or acquired. They may develop nearly anywhere in the body and usually require complete excision for eradication or they are likely to recur. Fluid filled sacs that are not cellular lined ...Read more

Mri says partial tear of anterior, posterior cruciate ligament, grade3 chondromalacia, subchondral cysts in medial tibial condyle, is operatn right thng?

See good knee...: This is purely an MRI reading of your knee.'partial' acl and PCL tears in your age group means very little to me unless you had a very significant , recent knee injury w/ a hemarthrosis .( which u don't have).'chondromalacia'( of what..Mfc, lfc, patella?) means you have a component of arthritis in your knee. See a qualified, respected knee surgeon to discuss your options . Best of luck! ...Read more

What does left middle cranial fossa arachnoid cyst mean?

Likely congenital: Typically found coincidentally when images obtained for very different purpose. Almost always present from birth, but on rare occasions can expand, but usually without mass effect. May be of value periodically to repeat scans to ascertain absence of issues. ...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

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

 MRI  shows complex tear posterior horn medial meniscus dem.both radial, horizontal components. Moderate size effusion Low grade tear poplitues muscle?

SurgicalRepair: Posterior Horn of the Medial Meniscus absorbs most of the weight of posterior compartment/This complex tear should be evaluated by a knee surgeon and all efforts made to repair it to prevent the further development of osteoarthritis.If it can not be surgically repaired than follow up closely for signs of pain and swelling with activities.A properly fitted Knee Brace may help too. Follow the advise of orthopedic surgeon.Physical Therapy may help as well ...Read more

7mm ovoid lesion fluid density shown within posterior inferior aspect of right basal ganglia small vessel coursing through it incidental virchow robin?

7mm ovoid lesion fluid density shown within posterior inferior aspect of right basal ganglia small vessel coursing through it incidental virchow robin?

Difficult to tell: without actually looking at the scan. Virchow Robin spaces are found normally and accompany blood vessels as they penetrate the brain. They contain cerebrospinal fluid and if they expand they can look quite pathological however it would be difficult to tell for sure without looking at the scan and knowing more. Would be happy to provide a virtual consult if needed. Best of luck! ...Read more

Mri found bilaterally along the inferior lateral aspect of the basal ganglion, either old lacunar infarctions or bilateral benign cysts. Thoughts?

Mri found bilaterally along the inferior lateral aspect of the basal ganglion, either old lacunar infarctions or bilateral benign cysts. Thoughts?

Either unusual: The chance of lacunar infarcts in a 23 yo is pretty low. Similarly, having "bilateral cysts" seems somewhat unlikely, nor am i sure what kind of "cysts" the radiologist would be referring to. Review your MRI with your doctor. ...Read more

What is a posterior osseous protuberance from the posterior aspect of the odontoid?

What is a posterior osseous protuberance from the posterior aspect of the odontoid?

Odontoid protuberanc: What is being described is excessive bone growth on the odontoid which is a bone unit at the top of the spine, at the base of the skull. If this extra bone is causing compression on the spinal cord then it might been to be removed. If there are no symptoms then one would just followed it with MRIs. ...Read more

Athroscopic debridement & menisectomy, partial medial & lateral. Grd1 oa changes lt medial femoral condyle, large posterior horn tear lateral meniscus?

Yikes: The wear on your lateral side and lateral meniscus tear is a not great. The lateral meniscus is responsible for balancing and distribution of force more so than the medial. Be very cautious returning to plant and pivot sports. ...Read more

Brain right ventricle 8mm lesion -cyst or tumor?

Brain right ventricle 8mm lesion -cyst or tumor?

Hard to say: If the interpretation on the MRI by the radiologist is that it is a cyst, then it is likely benign. It also depends if there is any area of enhancement that would suggest a tumor. Also if you have serial MRI scans, you can tell if it is getting bigger or changing which is more likely a tumor. The location in the ventricle is important too. If it obstructs the foramen it could be a problem. ...Read more

Horizontal Tear of the Posterior Horn of the Medial Menistic &Suprapatellar joint Effusion ,Articular Cartilage Loss & 3MM Medial Popliteal Cyst means

Horizontal Tear of the Posterior Horn of the Medial Menistic &Suprapatellar joint Effusion ,Articular Cartilage Loss & 3MM Medial Popliteal Cyst means

Arthritis and tear: The cartilage loss is similar to saying you have degenerative arthritis setting up in your knee. The meniscus is a cartilage cushion present in your knee, there is one present medically and one lateral, and you have a tear in one as well. I would go through your MRI with an orthopedic surgeon to discuss options. ...Read more

What does signal changes in the posterior left medial menicus and posterior lateral meniscus mean?

What does signal changes in the posterior left medial menicus and posterior lateral meniscus mean?

Degeneration: Mri scans image tissue by measuring hydrogen atoms such as are found in water (h2o - 2 parts hydrogen, 1 part water) . As a meniscus ages the tissue degenerates and is replaced by fluid which is mostly water. Increased MRI signal ( increased fluid) usually means some degeneration of the meniscus which is a consequence of aging. ...Read more

MRI says recurrent tear of surgically repaired posterior supra and infra tendons w/23mm of medial retraction& 23mm anterior to posterior gap.This bad?

Ask Orthopedic Surgn: The MRI just gives an anatomical report, it tells you nothing about how it moves. Your question is better posed relating to "function" (i.e., "can you still use the shoulder, & for how long?"). This question is best asked of the doctor who ordered the MRI (& should have a copy of the report). If you get no answer, take your MRI picture + report to an Orthopedic Surgeon. Use HealthTap Prime for ref ...Read more
