[Atypical debut of symptoms of cholangiocarcinoma.]
[cholangiocarcinoma]
Malignancy
of
the
sphenoid
sinus
is
rare
and
metastasis
from
a
cholangiocarcinoma
(
CC
)
to
this
location
is
even
rarer
.
We
present
a
74
-
year
-old
female
with
CC
metastasis
to
the
sphenoid
sinus
.
This
case
demonstrates
that
metastases
to
the
sphenoid
sinus
occur
and
that
the
tumour
can
have
its
origin
far
from
the
head
and
neck
region
.
Thus
,
the
possibility
of
metastasis
must
always
be
considered
when
discovering
a
tumour
in
the
sphenoid
sinus
.
