A ‘twist of fate’: Gall bladder torsion in a 10-year-old ramwith cerebrocortical necrosis (polioencephalomalacia)
Abstract
A 10-year-old ramwith central nervous signs was euthanased due to animal welfare reasons
and submitted for postmortem examination. The animal was previously treated
with antibiotics and cortisone. At postmortem examination, yellow discoloration and
malacia of the cerebrum were noted (polioencephalomalacia, cerebrocortical necrosis).
Ultraviolet light and histological examination of the brain confirmed this diagnosis,
which was considered the cause of the neurological signs. Inspection of the abdomen
showed an enlarged gall bladder due to a rotation about its long axis (torsion). Causes
of cerebrocortical necrosis in (small) ruminants are already described in the literature.
This case report will focus on the pathology of the gall bladder, which is the first
documentation of gall bladder torsion in a small ruminant.
