Adrenal schwannoma: a rare type of adrenal incidentaloma.
[adrenal incidentaloma]
Adrenal
schwannoma
is
a
rare
type
of
adrenal
incidentaloma
,
an
adrenal
lesion
found
incidentally
,
usually
on
imaging
or
autopsy
.
Computed
tomography
and
magnetic
resonance
imaging
are
tools
used
to
evaluate
adrenal
lesions
.
The
diagnosis
of
adrenal
schwannoma
,
however
,
can
not
be
made
on
imaging
alone
.
Surgical
resection
is
the
primary
means
of
management
of
adrenal
schwannomas
,
as
it
is
not
possible
to
distinguish
the
schwannoma
from
malignant
entities
simply
based
on
imaging
.
Histopathologic
features
of
adrenal
schwannomas
are
similar
to
those
of
schwannomas
found
at
other
sites
.
Conventional
schwannomas
,
consisting
of
alternating
Antoni
A
and
Antoni
B
areas
as
well
as
Verocay
bodies
,
have
distinct
microscopic
features
and
can
be
readily
distinguished
from
other
entities
.
Cellular
schwannomas
,
on
the
other
hand
,
consist
only
of
intersecting
fascicles
of
spindle
cells
or
Antoni
A
areas
,
resulting
in
a
wide
differential
diagnosis
.
Ancillary
studies
such
as
immunohistochemical
analysis
and
electron
microscopy
can
help
to
provide
a
specific
diagnosis
.
