Mesenteric Castleman disease

US features:
not specific, well-defined abdominal hypoechoic masses, particularly if deeply placed.
Sonography remains anyway useful for the evaluation of cervical and axillary Castleman's diseases,
in which the depiction of prominent peripheral vessels and penetrating feeding vessels on Doppler
can suggest the diagnosis of this uncommon disease.


Histology:
typical appearance of the hyaline-vascular type of Castleman's disease, with small germinal centers
of the lymphoid follicles traversed by a hyalinised blood vessel.
