Mammography Appearance of Filariasis - A Case Study
Authored by Biren A Shah*
Filariasis of the breast, most
commonly caused by a roundworm in the Filarioidea family, Wuchereria bancrofti,
can have pathognomonic findings of breast calcifications on mammography that
may be confused with other calcifications associated with malignancy. The
purpose of this report is to describe a classic presentation of breast
filariasis on mammography and distinguish it from other malignant
calcifications of the breast. Lymphatic filariasis is typically a benign
infection caused by Wuchereria bancrofti, native to tropical countries like
Nigeria, India and Indonesia. This parasite is transmitted by mosquitoes and
black flies that carry larvae from one human host to the next. The larvae enter
the bloodstream, infiltrate and obstruct the lymphatic vessels, and cause
potential vascular extravasation of the parasite into mammary tissue and later
become calcified. Patients may present with palpable, tender, mobile, firm, and
benign lumps on the breast and “serpiginous calcifications” on mammography.
Though the presentation of this infection in the breast is uncommon, it is
increasing in developed countries as people immigrate from areas where
filariasis is endemic. Active filariasis is conventionally diagnosed by
peripheral blood smear and, sometimes by fine needle aspiration, these
calcifications can indicate the presence of a past or current infection.
