Tuberculous abscess

Tuberculous abscesses are an uncommon presentation of tuberculosis, most often encountered in immunocompromised individuals (e.g. HIV/AIDS). Unlike the far more common tuberculomas (tuberculous granulomas), tuberculous abscesses contain pus with abundant identifiable organisms 1. The capsule that surrounds the necrotic purulent core is similar to more common bacterial abscesses, lacking granulomatous reaction prominent in tuberculomas 1. They also lack the usual pus and neutrophils usually present in pyogenic abscesses.2 Spectroscopy usually shows lactate and lipid peak.2

The medical literature documents that there are multiple phenomenon described as tuberculous abscesses including intracranial tuberculous abcesses and dermal abscesses also known as gummas or metastatic tuberculous abcesses.
