hi, losergirl, your answer, ALL, is right as in nms, review for usmle step 2. but i am not so convinced is because usually ALL presents "fatigue, pallor, petechiae and bleeding, and fever." instead of "headache" (am i right?) in this question, the main symptom is "head on and off for 1wk". and because neuroblastoma is the most common tumor of cns. so why not neuroblastoma?

listen dude, neuroblastoma is malignancy of neural crest cells. Tumors may arise any where neural crest cells are present (adrenal glands, sympthetic ganglia). It represent 8% of all childhood tumors and is the most common solid malignancy in children OUTSIDE of the CNS. 70% are in abdomen, and half of these r in adrenal. the findings on PE depend on presentation of pt: e.g., abdominal mass that is hard, smooth n nontender, or thoracic tumor present with respiatory distress or detected accidently in post mediastinum, or as palapable head n neck tumors etc. i hope this helps. Read neuroblastoma from kaplan pediatric notes if u got the book :|
