Results
Case 1: A 7-years-old-boy had developed Brown syndrome on his left eye,
following a Valsalva maneuver during a circumcision procedure under local anesthesia (Figure 1).
The MRI study,
that was held approximately 2 weeks after the onset of the symptoms revealed enlargement of tendon-trochlea complex on the right side.
The tendon-trochlea complex showed some high signals on T1 weighted images,
which was attributed to a possible hemorrhage (Figure 2).
The patient was treated conservatively and the symptoms resolved spontaneously (Figure 3).
Case 2: A 12-years-old girl complaining of diplopia was diagnosed as Brown syndrome on her physical examination (Figure 4).
MRI of the orbit showed that the left superior oblique was swollen and diffusely bright on T2 weighted images.
On post-contrast fat suppressed series both the muscle and some of the surrounding fat tissue was enhancing homogeneously (Figure 5).
The patient was diagnosed as superior oblique myositis and treated with p.o.
non-steroidal anti-inflammatory drugs.
Her ophthalmological examination was within normal limits after treatment (Figure 6).
Case 3: A 5-years-old girl admitted to hospital with the complaint of acquired squint.
The patient was diagnosed as right Brown syndrome on ophthalmological examination (Figure 7).
On MRI the tendon-trochlea complex was enlarged on the right side with high signal intensity on T2 weighted images.
Ring enhancement of the trochlea itself was found to be significant for inflammation of the complex (Figure 8).
Her ocular motility improved shortly after the administration of steroids Figure 9)
