In severe cases, the involved lymph node tuberculosis continues to develop and form cold abscesses or ulcers after absorption. The other is that after primary tuberculosis infection, the Mycobacterium tuberculosis in the blood enters the medial cervical lymph nodes with the blood, causing cervical lymph node tuberculosis; it can also be infected from the waist and abdomen lymph nodes, and then spread to the deep lymph node group for secondary infection, which is more common in the incidence of cervical lymph node tuberculosis. common.
