within the granuloma is seen as a consequence of delayed hypersensitivity reaction and is composed of dead macrophages and bacilli.
16 The two histological features which specifically point towards the diagnosis of tuberculosis are variation in the size of the granulomata and the presence of caseation necrosis
Contrast enhanced CT scan (CECT) of neck showed multiple lymph nodes at level IV on the right side and in the right supraclavicular region showing peripheral rim enhancement with central caseation necrosis
(Figures 4, 5, and 6).
An ultrasound guided biopsy of liver mass showed chronic lymhoplasmacytic inflammation with caseation necrosis
and giant cells surrounded by epithelioid histiocytes (Figure-3).
4) Hip infection is similar to progression in lungs with chronic granulomatous inflammation and caseation necrosis
29%) were reported tuberculosis with extensive Caseation necrosis
and n=3 (4.
They consist of accumulations of epithelioid histiocytes with Langhans giant cells and varying amount of caseation necrosis
in the center.
A synovial biopsy taken from the knee detected granulomatous inflammation with caseation necrosis
Non-suppurative necrosis, including caseation necrosis
, was present.
In CT investigation, mediastinal lymph node was typically seen with a central hypodense area corresponding to caseation necrosis
and ring enhancement after contrast administration (2) (Figure 2).
proliferans, and, most notably, extensive caseation necrosis
