What would be the differential diagnosis in this case (unilateral axillary high attenuation lymphadenopathy)?
Metastasis from breast cancer, tuberculosis (due to intranodal calcifications), lymphoma and other lymphoproliferative disorders (like Castleman disease).
Bilobulated and well-defined right axillary mass that shows homogeneous intense enhancement, with a small central hypoattenuating region. Note the presence of some prominent feeding vessels in the posterior aspect of the lesion.
