Facial colliculus syndrome: MRI

61 year old male presence with conjugate palsy with peripheral facial nerve palsy on the left. The MRI suggests tiny dot of bright signal on DW consistent with possible facial colliculus region infarction suggesting facial colliculus syndrome.

Teaching points by Dr MGK Murthy, Abdul Hameed:

-        Typically presence with peripheral facial nerve palsy and conjugate gaze palsy in view of ipsilateral lateral rectus palsy (abducens  nerve nucleus nerve involvement) and interneurons connections in the medial longitudinal fasciculus effecting the other side medial rectus innervation.

-        Facial nerve palsy is on account of breach of facial nerve fibers at the Genu arching behind the 6th nerve nucleus.
