Disseminated mycobacterial avium complex infection causing abdominal adenopathy and splenomegaly

Case contributed by Dr Michael P Hartung


Abdominal pain, HIV+.

Patient Data

Age: 60 years
Gender: Male

Mesenteric adenopathy and haziness, several lymph nodes have lower attenuation centrally. Mild retrocrural and retroperitoneal adenopathy.  

Splenomegaly with subtle areas of hypoenhancement anteriorly. 

LLL opacity. 

Case Discussion

US-guided biopsy confirmed myocobacterial avium complex infection in the mesenteric lymph nodes. It would be reasonable to be concerned about lymphoproliferative disorder given the RP and mesenteric lymph nodes with splenomegaly, but it is important to remember other cases such as disseminated infection, particularly in immunocompromised patients.
