Identification of suspicious mediastinal metastases by CT or PET should always be followed by histologic assessment of mediastinal and hilar lymph nodes
for accurate staging.
Should hilar lymph nodes
be expected in radical nephrectomy specimens?
17) Some studies adopt the notion that any visible mediastinal and hilar lymph nodes
on CT are abnormal in children.
1) The most commonly affected sites are the lungs, hilar lymph nodes
, liver, eyes, skin, bones, and the nervous system; only 0.
Usually, the lungs and the hilar lymph nodes
The hilar lymph nodes
were matted forming a large mass with central caseous-like necrosis that eroded through the left main bronchus that contained caseous material.
Pathology showed noncaseating granulomas involving the mediastinal and hilar lymph nodes
This demonstrated the presence of enlarged and heterogeneous mediastinal and right hilar lymph nodes
, concerning for metastatic disease.
At least two hilar lymph nodes
were infiltrated by similar granulomas: one was normal sized, and one about 4 times larger than normal (Figure 7a).
Sarcoidosis can affect several organs and tissues, most commonly the hilar lymph nodes
, eyes, skin, and mucosal surfaces.
pN1: Metastasis in ipsilateral peribronchial and/ or ipsilateral hilar lymph nodes
, and intrapulmonary nodes, including involvement by direct extension
Multiple splenic hilar lymph nodes
and mesenteric nodes were also positive for disease.
