Proptosis Most common cause of unilateral and bilateral
proptosis in an adult is thyroid eye disease Most common cause of unilateral proptosis in a child is cellulitis Most common cause of bilateral proptosis in a child is metastatic neuroblastoma and leukemia

Proptosis In cases of unilateral proptosis must carefully
differentiate between true protrusion and enophthalmos of the other eye
Most common causes of enophthalmos in a child is microphthalmos
Most common cause of enophthalmos in an adult is old trauma but must always rule out scirrhous breast cancer mets and sclerosing pseudotumor

IgG4 Orbital Inflammation Variant Systemic variant of sclerosing orbital inflammation First recognized as a discrete entity in 2003 with extra
pancreatic manifestations in autoimmune pancreatitis1 Now has been identified in virtually every organ system
including the orbit1 Dense lymphoplasmacytic infiltration with plasma cells
rich in IgG41 Produces elevated levels of IgG4 in the blood and can
respond to systemic immune modulation/suppression1

Globe Dystopia When evaluating a patient with proptosis, it is also
important to see if the eye is being moved in a specific direction or if the movement is purely axial
The differential diagnosis is significantly impacted by relative movement of the globe Globe typically moves opposite the location of the lesion

Case #1 Superonasal Mass 8 y.o old white male presented with one month history
of rapid proptosis and inferolateral displacement of the globe
First though to be a “bug bite” Then thought to be pre-septal cellulitis that did not
respond to oral antibiotics When proptosis, dystopia, and decreased motility
readily apparent, referred to SEI

Case # 1 Superonasal Mass MRI showed a large superonasal mass extending to the
apex Lid crease incision and anterior orbitotomy performed Large bluish, highly vascular tumor identified,
debulked, and biopsied Tumor was mostly solid but seemed to have areas that
were liquefied Most of incision closed but external drain placed due
to vascular nature of mass

Orbital Rhabdomyosarcoma
Usually presents as a rapid onset of proptosis with inferior / infero-temporal displacement of the globe
Past history of trauma may delay diagnosis Often simulates an orbital cellulitis due to rapid onset 4 histopathological subtypes:
Embryonal - most common Alveolar - worst prognosis
Usually has rearrangement of FOXO1A (1;13 or 2;13) Differentiated (pleomorphic) - least common, best prognosis Botryoid (a variant of embryonal)

proptosis, decreased motility, redness, and chemosis Started on 50mg of oral prednisone with rapid

Orbital Cellulitis and SPA Smaller SPAs in kids can be watched on IV antibiotics
and many respond without drainage Large SPAs should be drained Preferred method is to drain the sinuses and abscess at
the same time to prevent recurrence This case shows that careful follow up also important
and if does not respond promptly should re-image!
