[Lewis-Sumner syndrome presenting unilateral quadriceps amyotrophy as an initial symptom].
[focal myositis]
We
report
a
55
-
year
-old
man
with
a
chief
complaint
of
wasting
and
weakness
of
the
left
quadriceps
muscle
.
At
age
54
,
he
noticed
difficulty
in
running
and
weakness
in
the
left
thigh
,
which
gradually
progressed
.
On
the
first
admission
to
our
hospital
,
based
on
the
nerve
conduction
studies
(
NCS
)
,
the
muscle
biopsy
findings
showing
neurologenic
changes
,
and
no
abnormality
of
spinal
MRI
,
we
diagnosed
as
unilateral
quadriceps
amyotrophy
,
which
resulted
from
an
atypical
form
of
spinal
progressive
muscular
atrophy
.
One
year
later
,
he
showed
the
bilateral
hand
weakness
,
conduction
blocks
on
the
right
median
and
ulnar
nerves
by
NCS
,
and
the
presence
of
serum
anti-
GM
1
antibody
.
From
these
findings
,
Lewis-
Sumner
syndrome
was
diagnosed
.
The
therapy
of
high
-dose
intravenous
immunoglobulin
moderately
improved
his
symptoms
.
The
clinical
symptoms
of
quadriceps
amyotrophy
is
produced
by
various
disorders
including
spinal
progressive
muscular
atrophy
,
spinal
extradural
arachnoid
cyst
,
rimmed
vacuole
myopathy
,
Becker
dystrophy
,
limb
-girdle
dystrophy
,
and
focal
myositis
.
However
,
there
have
been
no
reports
of
a
case
of
Lewis-
Sumner
syndrome
.
It
is
important
to
consider
Lewis-
Sumner
syndrome
in
the
differential
diagnosis
of
quadriceps
amyotrophy
.
