Findings and procedure details
In the light of those aforementioned details,
we will now discuss imaging findings of MBC and present some cases.
Sonography:
MBC typically presents with same sonographic imaging features as in women.
In most of the cases,
it arises from subareolar region and it appears as nonparallel,
hypoechoic solid lesion with irregular and spiculated contours (Figure 1).
Lesions generally have hyperechoic halos due to desmoplastic reaction and show acoustic shadowing.
One should also examine the axillary region since half of the MBC present with axillary lymph node involvement.
Mammography:
As in women,
mammography is an effective tool in diagnosis of MBC.
Mammography is a diagnostic tool since secreening is not recommended in male population due to low incidence of MBC.
Patients with palpated breast lump,
tenderness and enlargement of breast are candidates for mammography.
Bilateral mammograms should be obtained with CC (craniocaudal) and MLO (mediolateral) projections.
MBC typically appears eccentrically.
The margins can be seen well-circumscribed (intracystic breast cancer is much more common in males compared to females),
lobulated or spiculated (Figure 2-3-4).
The lesions may cause nipple retraction,
skin ulcerations and induration in breast skin.Even rare,
microcalcifications may accompany the MBC.
These calcifications generally appear coarser,
lesser in number when compared to females (Figure 3).
Magnetic resonance Imaging:
Magnetic resonance imaging (MRI) is a reliable imaging modality in MBC.
MRI may demonstrate the contrast enhancement pattern of the suspicious lesion,
possible lesion accompanying gynecomastia,
and possible chest wall invasion.
MRI can be performed if the initial diagnostic testing is equivocal (Figure 5-6).
