re CT of sickle cell pt - ethmoid sinsuses looked hypertrophied. Given the history i chose ethmoid bone infaction. yes sinusitis can give u pain around the eye and on palpation but does it give pain during eye movement and periorbital skin involvement?? which is what the question said i think... re pt with macular rash, thrombocytopenia, fever + who had taken antimalarials - was this HIV?? i guess it could have been dengue but there was no mention of headache, retro orb eye pain, myalgias etc.
