TPHA, QuantiFERON-TB, Western blot test for Lyme disease, and parasitological stool exam. A brain and spinal cord MRI was performed (Figure 1), revealing widespread arachnoiditis and small septated cysts with CSF-like signal in the cisterna magna, within the fourth ventricle, and at the level of L3-L4. These findings were likely due to arachnoiditic adhesions.
