Presentación:
A 56-year-old woman came to our emergency department referred from ophthalmology for acute pain due to supraaduction of the left eyeball.
Discusión:
Acute trochleitis is an unusual consultation in radiology services because its diagnosis use to be clinical. It consist of pain in the superonasal orbital angle, which is typically exacerbated by vertical eye movements, mainly supraduction, the field of relaxation of the superior oblique muscle. It is more frequent during the pediatric age. The case that concerns us is of sudden onset in adult woman, so it was referred to our emergency department to rule out other acute intraorbital pathology causes, as nontraumatic caroticocavernous fistula or an orbital cellulitis. We decided to perform an ultrasound instead of a orbit CT. In the orbit ultrasound we can appreciate edema in the region of the trochlea not present on the contralateral side, this finding is very specific, because only uniform echogenicity of the intraorbital fat is found in non-patologic patients. An increase in Doppler flow is not usually found. Trochleitis was recently described as a cause of chronic headache type, so it is an emerging pathology and whose requests can increase significantly in radiodiagnosis services over the next few years, knowledge of sonographic findings can avoid performing CT to these patients
