A) 94% of cases are sporadic B) Patients with sporadic retinoblastoma do not pass their genes to their offsprings C) Calcification in the tumor can be detected on ultrasound scan D) Presence of extraocular extension answer given is A...i think the answer should be C |
| drnisha Total Posts: 11 | Posted: Wed Dec 16, 2009 02:29 am hey i think d ans is A only..as 55-60% cases r sporadic...n ya calification can be detected on ultrasound..though CT is way better than it. |
| sahilstanlean Total Posts: 24 | Posted: Thu Dec 17, 2009 03:17 am well in the books % is given exactly as 94%..and generally calcification is not visible on USG..(though i am not sure about the later one) |
| madanpopuri Total Posts: 1 | Posted: Tue Dec 22, 2009 04:27 pm is the answer.answer is bitween b n c.bcz usg is useful in r.b.for detection of calcification,answer is most probably b |
| ishan Total Posts: 3 | Posted: Tue Dec 22, 2009 05:18 pm i believe d answer is A only.........50-70% cases r sporadic(in 99% studies) wd 70 being d higher limit.... at d same time though calcification is best seen on imaging studies lyk ct/mri....a usg will show incresed thickness which wll correlate well wid calcificatipn of d tumour.... |
