TECTAL GLIOMA


Tectal glioma
Subtype of brainstem glioma in children with a more benign clinical course; low grade astrocytomas
No gender predilection
Present with symptoms of increased intracranial pressure
     Headache (59%), papilledema (34%), visual problems, ataxia, vomiting, nausea, etc.

Radiographic findings:  
Located between the aqueduct of Sylvius and the 4th ventricle 
          Enlarged tectum
Obliterate the aqueduct of Sylvius
Hydrocephalus

MRI is diagnostic:
                    Bulbous mass in the region of the quadrigeminal plate
                    Low T1, high T2 signal intensity
                    Enhancement can be minimal or absent in small lesions
CT:
                    Variable appearance
                    May show calcification or cystic change
                    Displacement of the ventricular system if present

Location not amenable to resection; shunting is necessary for long term survival.
Increasing size (>2.5 cm) and worsen symptoms may require further treatment beyond CSF shunting; i.e. radiation
*Note: "Distinction between a compressed tectum from tectal astrocytoma can be difficult, particularly because astrocytomas in this region are generally low grade and small lesions often do not enhance.  Return of the tectum to a normal thickness after shunting is virtually diagnositic of a compressed tectum, whereas hyperintensity on T2 weighted images indicates tumor." Freidman, et al.

  1. I had my TL a little more than a year ago when my third child was born via c-section. I was not told ANYTHING about the possible side effects of having this procedure. Since then I have experienced heavy bleeding lasting sometimes 3 weeks out of the month, weight gain, severe mood swings. Severe cramping, changes to my libido, severe depression accompanied by suicidal thoughts, headaches, migraines, many new symptoms & older issues are now exacerbated. The father of two of my children doesn't want me anymore. I've become too much of a pain in the ass I guess. We don't talk. We don't sleep in the same bed. I think he might really think I am crazy... & maybe I am. I feel crazy a lot of the time.
    I'm unpredictable. I feel so angry about the whole thing & now what was once a mild fear of doctors has exploded into full on white coat syndrome that causes me to have a panic attack/hypertensive emergency (severe increase in blood pressure) whenever I have to deal with them. I'm not sure what to do... I fear the next time I have to see a doctor I'll have a stroke or a heart attack from the stress & anxiety of it... what do I do? I take my time and keep searching on internet looking for natural healing that how I came across Dr Itua herbal center website and I was so excited when Dr Itua told me to calm down that he will help me with his natural remedy I put my hope on him so I purchase his herbal medicines which was shipped to my address I used it as prescribed guess what? I'm totally healed my cramp pain is gone completely I also used his Anti Bacteria herbal medicines it's works for me very well I want anyone with health problem to contact Dr Itua herbal center for any kind diseases remedies such as Parkinson, Herpes, ALS, MS, Diabetes, Hepatitis, Hiv/Aids,Cancers, Men & Women Infertility, I got his email address drituaherbalcenter@gmail.com he has any kind of herbal remedies for women & men also for our babes. I really miss my Hunni...he's a fantastic father & a good man. He doesn't deserve this. I feel like an empty shell of who I used to be...
