[A radiographic classification for sarcoidosis based on the ILP/UC classification bacillus].
A scheme was devised for semiquantitative description of 79 cases with sarcoidosis using the graphic terminology of International Labour Office and Union International Contre Le Cancer (ILO/CU) for the pneumoconioses. Among 56 patients with stage II, "linear-irregular" categories s t u (50%) and "reticulonodular" categories x y z (28%) predominated while "rounded" categories p q r (22%) were unusual. Among 13 patients with stage III s t u and x y z opacities were found in 38% of patients while p q r only in 23%. The opacities in both stages of sarcoidosis were most severe in the bilateral lower lobes. It was concluded that the traditional method for classification of sarcoidosis was helpful to give the qualitative diagnosis of the disease, but it did not provide objective description of the type and degree of pulmonary involvement. ILO/UC classification was an important supplement of traditional method as ILO/UC could be used to grade the type (linear irregular, rounded and reticulonodular opacities), severity and location of opacities. Therefore, the two methods should be used in combination so as to judge the location, type and severity of intrathoricic sarcoidosis.
