granuloma like tuberculoma with a solid centre are hypointense or isointense on both T1 and T2W1 and show ring enhancement.
These tubercles show characteristic amorphous caseating
necrosis which may rupture into surrounding structures, such as the airway and blood stream, causing endobronchial or hematogenous dissemination.
Peritoneal biopsy samples contained acid-fast bacilli and caseating
granulomas; PCR for M.
In addition, the patient had a positive AFB stain in his urine specimen and he had cervical caseating
Biopsy specimens from the ulcer margin showed caseating
granulomas containing Langhans giant cells.
The second specimen exhibited features of a typical tuberculous lymphadenitis, including areas of tuberculous granulation tissue with full-blown caseating
epithelioid cell granulomas, Langerhans' giant ceils, and lymphocytic infiltrates.
Histopathology revealed caseating
granulomas diagnostic of TB, with no evidence of malignant cells.
Granuloma formation with caseating
necrosis should also point towards a differential diagnosis of infectious etiology as opposed to MCD.
Histological examination of his adenoids showed caseating
granulomas and acid- and alcohol-fast bacilli.
Histopathology (Figure 4) revealed multiple caseating
granulomas and Langhan's giant cells, which were suggestive of tuberculosis (TB).
tuberculosis and those whose biopsy specimens had caseating
granulomas that showed marked improvement after treatment.
12) Histologic preparation may reveal acid-fast organisms or simply caseating
granulomas without identification of M tuberculosis bacteria, although granulomas can also represent a reaction to the prosthesis.
