| Hilar lymphadenopathy with other pulmonary infiltrates is infrequent and thought to represent reactive hyperplasia. |
| Radiologic investigations revealed a 5-cm right lung mass with enlarged hilar and mediastinal lymph nodes. |
| Group A contained subjects with changes such as haziness, hilar prominence, fine mottling, and reticulation, all of which were considered to result from gas exposure. |
| A hilar groove is located at the centre of the seed hilum area, and consists of more elongated macrosclereids. |
| Neither the hilar structures nor the renal pelvis were involved. |
| Flow cytometric analysis was performed on both splenic tissue and splenic hilar lymph nodes. |
