Hello,

I received the below diagnosis about 10 years ago. The tests were done because I was suffering from depression, and still am today, as well as severe anxiety. I'm wondering if there is any link here or not. I'm pretty uninformed about the exact nature of arachnoid cysts. Thanks in advance for any responses.

Diagnosis/Reason for test: Depression

Magnetic Resonance Imaging of the Brain

Findings:

The sagittal sections and the transaxial sections after Magnevist are degraded by patient motion
limiting evaluation.

The cortical sulci, sylvian fissures and basal cisterns did not seem unusual. There however
appears to be an unusual but relatively small density in the anterior inferior aspect of the right
temporal fossa. Its signal characteristics are similar to those of cerebral spinal fluid. The finding
and location would suggest an arachnoid cyst which is more likely congenital in nature than
secondary to trauma, infection or other etiology. This by itself is therefore likely of questionable
significance. The ventricular system appeared to be within normal limits in size and shape. There
was no definitive alteration to indicate ventricular displacement or other diagnostic abnormality.
Dependent upon the clinical findings and course, additional studies might be considered for
further evaluation.
