This year we received 10 cases of fungal lymphadenitis <\/strong>in calves, out of a total of 55 suspected tuberculosis samples (18.2%). In this post we have compiled images to familiarize you with the variety of the macroscopic looks of these lesions.<\/p>\n

Under no circumstances should this sort of lesions not be sent to the laboratory for analysis, as macroscopically it cannot be ruled out that they are tuberculous granulomas<\/a>.<\/strong><\/p>\n

In all the cases presented below, the laboratory diagnosis was based on the identification under the microscope of the presence of fungal hyphae<\/strong> inside the lesions, but the causal fungal species was not identified. You can read a previously published post where the fungus Rhizomucor pusillus<\/em><\/strong><\/a> was identified.<\/p>\n

Mediastinal and retropharyngeal lymph nodes of a 13-month-old male Belgian blue calf. It also had lesions in his left tracheobronchial lymph node. In this case the lesions did not crackle when sectioned.<\/p><\/div>\n

Mesenteric lymph nodes of an 11-month-old crossedbred male calf. You can see more pictures of this case in a previous post in the self-learning section \u201cWhat is your diagnosis? (81)<\/a> \u201d. These were spherical lesions, well circumbscribed and with a necrotic core.<\/p><\/div>\n

Mesenteric lymph node of a 14-month-old male Friesian calf. Multiple 2-3mm lesions are observed throughout the lymph node. The consistency of the nodules is hardened but does not crackle upon section.<\/p><\/div>\n

Left tracheobronchial lymph node of a 10-month-old crossbred female calf. The carcass showed no more visible lesions, when sectioned the lesion crackled.<\/p><\/div>\n
