Introduction of brain stem gliomaIntroduction of brain stem glioma
• Classification - diffuse intrinsic pontine - tectal - cervicomedullary
• Most common -pontine glioma -grave prognosis• All have fatal termination• Malignant for practical purposes -location -transient responsiveness to
irradiation

Fate of the disease Swallowing and speaking difficulty

• Average survival without treatment is 15 months from the date of the patient’s first hospital admission

Brain stem glioma…………Brain stem glioma…………• Causes
Increased incidence in patient with neurofibromatosis (up to 14% in some reports).
children irradiated for tinea capitis –increased incidence of CNS tumors, especially meningiomas, gliomas, and nerve sheath tumors
no genetic or molecular markers have been recognized
![Page 31: Case of the month](https://reader035.vdocuments.us/reader035/viewer/2022062409/56814cf9550346895dba0b42/html5/thumbnails/31.jpg)
Brain stem glioma…………Brain stem glioma…………
• Work up• Lab Studies
– Blood chemistry not useful for diagnosis– cerebrospinal fluid (CSF) examination
protein may be elevated
• Tissue confirmation only in case of exophytic growth
![Page 32: Case of the month](https://reader035.vdocuments.us/reader035/viewer/2022062409/56814cf9550346895dba0b42/html5/thumbnails/32.jpg)
Brain stem glioma…………Brain stem glioma…………
• Imaging Studies• MRI
o the diagnostic test of choice. o differentiate vascular malformations and other
processes that can be misdiagnosed as a brainstem glioma on CT scan.
o an expansile, infiltrative process with low-to-normal signal intensity on T1-weighted images and heterogeneous high-signal intensity on T2-weighted images, with or without contrast enhancement
o delineate the extent of infiltration of the leptomeninges and the surrounding structures
o contrast enhancement in a tectal lesion should raise suspicion of a metastatic lesion
![Page 33: Case of the month](https://reader035.vdocuments.us/reader035/viewer/2022062409/56814cf9550346895dba0b42/html5/thumbnails/33.jpg)
Brain stem glioma…………Brain stem glioma…………
• CT Scan– appropriate choice when MRI is not available – sensitivity of and characterization of tumors by CT are
poorer – calcifications, cystic changes, and displacement of the
ventricular system – lower brainstem lesions often not apparent
• Arteriography – in differentiating vascular lesions, including tumors, from
gliomas
![Page 34: Case of the month](https://reader035.vdocuments.us/reader035/viewer/2022062409/56814cf9550346895dba0b42/html5/thumbnails/34.jpg)
TreatmentTreatment
• Medical Care • Treatment frustrating –new therapy little benefit over
conventional treatment with radiotherapy alone.• Adjuvant chemotherapy is not used in children • effectiveness of chemotherapy at relapse is uncertain
• Focal radiotherapy – cornerstone of treatment – can improve or stabilize the patient's condition – 54-60 Gy, with doses up to 72 Gy given with
hyperfractionation – not demonstrated efficacy in children
![Page 35: Case of the month](https://reader035.vdocuments.us/reader035/viewer/2022062409/56814cf9550346895dba0b42/html5/thumbnails/35.jpg)
Treatment…Treatment…
• Radiotherapy…– Response to radiotherapy depends on
• tumor location,• histological type, and • response to early treatment • exophytic tumors better survival rates than without an
exophytic component
– transient clinical remission in 60% of the children– first improvement seen after 3-6 weeks of treatment– improvement noted by partial clearing of cranial
nerve signs
![Page 36: Case of the month](https://reader035.vdocuments.us/reader035/viewer/2022062409/56814cf9550346895dba0b42/html5/thumbnails/36.jpg)
Treatment…Treatment…
• Surgical Care • impossible due to location of tumor
• Palliative Care• hydrocephalus
• ventriculostomy or ventriculoperitoneal shunting
• difficulties in swallowing and diminished gag reflex
• gastrostomy such as the percutaneous esophagogastrostomy (PEG).
• multiple upper respiratory infections, pneumonia, or altered voice
• ventilatory assistance.
