RESUMO
Intravascular papillary endothelial hyperplasia (IPEH) is a rare cause of orbital mass which can affect healthy individuals of any age/sex/race/region. It usually requires a histopathological examination, characterized by the appearance of papillary proliferation of vascular endothelial cells within the lumen of the blood vessel, for the final diagnosis. One should be aware that this is a highly vascular lesion which can cause excessive intraoperative bleeding and incomplete removal can lead to recurrences. IPEH of the orbit/eyelid has been reported in few parts of the world as isolated case reports but none from India so far.
RESUMO
We report a case of significant unilateral left proptosis after a fall in a 10-year old child. Magnetic resonance imaging showed an extraconal hyperintense orbital mass extending into the maxillary sinus which was opacified. After drainage the proptosis resolved. The cause of the acute proptosis was haemorrhage within an orbital lymphangioma.
Se reporta el caso de una proptosis izquierda unilateral significativa en un niño de diez años de edad después de una caída. La tomografía por resonancia magnética mostró una masa orbitaria hiperintensa extracónica que se extendía hasta adentro del seno maxilar, opacificándolo. Después del drenaje, la proptosis se resolvió. La causa de la proptosis aguda fue la hemorragia dentro de un linfangioma orbitario.
