A

ewing sarcoma!!! -> xray can also show central lytic lesion with motheaten appearance

NOT osteomyelitis as usually involves long bones, no history of trauma or immune deficiency, histopathology would show inflamatory cell invasion

NOT osteosarcoma as typically found in metaphysis of long bones and biopsy would show sheets of pleomorphic cells surrounded by osteoid

Q

flattening of right occiput + anterior displacement of right ear and forehead. neck mass on right SCM muscle when head turned to right

postural deformity of the neck!!! = congenital muscular torticollis. limited head motion increases risk of positional plagiocephaly

craniosynostosis (premature closure of cranial sutures) can also cause plagiocephaly but head tilt and neck mass wont be seen
