However, the clinical presentation and radiological examination are often sufficiently characteristic to suggest the diagnosis.

We report 15 patients with radiologically diagnosed diffuse interstitial infiltration of lung, 13 of whom had lymphangitic carcinomatosis either on clinical follow-up, cytological or pathological examination. Cytology by percutaneous fine-needle aspiration biopsy was positive for malignant cells in 11 of the 13 patients.
