Central neurocytoma Question 2: Which of the following statements is true regarding this tumor? A. They are predominantly supratentorialB. Posterior fossa tumors in adults have a good prognosisC. Spinal tumors have a bad prognosisD. IDH 1 and 2 mutations are present in 100% cases. Question 3: Identify the variant of the tumor shown in the image below. A. TancyticB. MyxopapillaryC. SubependymomaD. Anaplastic Question 4: Which of the following statements is true regarding tancytic ependymoma? A. GFAP negativeB. Abundant rosettesC. Can be confused with pilocytic astrocytoma D. WHO Grade 1 Question 5: Identify the FALSE statement regarding the variant of ependymoma shown below Image credit- http://www.twitter.com/DrAldehyde A. WHO Grade 1B. Arises from filum terminaleC. Aggressive clinical courseD. Mucin stains positive Question 6: TRUE statement regarding recent molecular classification (WHO CNS 2021 5th edition ) of ependymoma is A. Spinal ependymomas with MYCN have a good prognosis B. ZFTA Fusion- favorable prognosisC. YAP Fusion- poor prognosisD. Spinal ependymomas with NF 2 mutation- favorable prognosis ANSWER- Question 1 Correct answer is B- Ependymoma Ependymomas are characterized by perivascular rosettes and ependymal rosettes which have an empty central lumen Types of rosettes ANSWER- Question 2 CORRECT ANSWER IS B 🐱 Majority of of Ependymomas are infratentorial. 🐱Posterior fossa tumors in children have a poor prognosis (PF-A)- associated with loss of H3K27me, whereas Posterior fossa tumors in adults have a god prognosis (PF-B)- H3K27me is retained. 🐱 Spinal ependymomas have a good prognosis, whereas a small number of ependymomas associated with MYCN have a poor outcome. 🐱IDH 1 and 2 are associated with astroctyomas and oligodendroglomas but nor ependymomas. ANSWER-Question 3 CORRECT ANSWER IS A Diagnosis is TANCYTIC EPENDYMOMA, 🐱 Tancytes are cells with fibrillary processes which line ventricles along with ependymal cells. Types of tancytes ANSWER – Question 4 Correct They are GFAP positive 🐱Confused with pilocytic astrocytoma because of the prominent fibrillary projections 🐱It is a GRADE II Ependymoma 🐱 Ependymal rosettes and pseudorosettes are scanty in tanytic ependymoma, which makes diagnosis challenging. ANSWER- Question 5 Correct answer is C💀Diagnosis is myxopapillary ependymoma💀It is a Grade II Tumor according to latest WHO💀It is common in adults and arises from the filum terminale💀It is clinically indolent ( nor aggressive)💀Stains for Mucin is positive. Mucin stains positive in myxopapillary ependymoma ANSWER – Question 6 Correct answer is D Spinal ependymomas with NF2 mutation has a good prognosis Summary of latest molecular updates in ependymoma Share this:FacebookTelegramWhatsAppMoreLinkedInTwitterLike this:Like Loading...
