Transient total mesencephalic locked-in syndrome after bilateral ptosis due to basilar artery thrombosis.
[locked-in syndrome]
Locked-
in
syndrome
(
LIS
)
usually
occurs
as
a
result
of
pontine
lesions
and
has
been
classified
into
various
categories
on
the
basis
of
neurologic
conditions
,
of
which
transient
total
mesencephalic
LIS
is
extremely
rare
.
A
53
-
year
-old
man
presented
with
bilateral
ptosis
followed
by
a
total
locked-
in
state
.
In
the
clinical
course
,
the
patient
successfully
recovered
with
only
left
slight
hemiparesis
and
skew
deviation
remaining
.
Magnetic
resonance
imaging
revealed
multiple
ischemic
lesions
caused
by
thrombosis
at
the
top
of
basilar
artery
,
including
the
bilateral
cerebral
peduncles
,
tegmentum
of
the
midbrain
,
and
the
right
cerebellar
hemisphere
.
Antecedent
bilateral
ptosis
before
the
locked-
in
state
may
be
related
to
ischemia
in
the
central
caudal
nucleus
of
the
oculomotor
nuclei
.
We
should
pay
attention
to
this
easily
missed
condition
during
the
treatment
of
ischemic
stroke
involving
the
basilar
artery
.
