Crhon's disease may have an association with non caseating
granulomas in the wall of the intestine in 40-60% of patients.
Mycobacterium marinum infection of adult zebrafish causes caseating
granulomatous tuberculosis and is moderated by adaptive immunity.
We showed in the histological section that calcifications were observed in areas of caseating
central necrosis, and these calcifications were revealed in every radiological examination on our patient that contained a chest radiograph.
Fever of unknown origin and isolated non caseating
granuloma of the marrow: could this be sarcoidosis?
USG guided lymph node fine needle aspiration cytology was performed in 15 subjects revealed caseating
tuberculosis was cultured, if acid-fast bacilli were identified on ZN staining, or if histopathological examination demonstrated the presence of caseating
Frozen and permanent sections showed caseating
granuloma with necrosis.
A transesophageal biopsy showed caseating
epithelioid-cell granulomas with Langhans-type of giant cells and a lymphocytic rim, highly consistent with tuberculosis, although ZN stain was negative (Fig.
Findings on analysis of the primary ulcer--which contained caseating
necrosis with florid granulomas, Langerhans' giant cells, and abundant epithelioid cells--were strongly suggestive of tuberculosis (figure 3).
MR with contrast allows differentiation of noncaseating from caseating
Possible causes include hypothalamic or pituitary lesions, such as tumors or caseating
lesions, hypophysitis, hyperprolactinemia, thyroid disease, or constitutional delay An MRI of the hypothalamic-pituitary area should be obtained.
