Pulmonary lymphangitic carcinomatosis is a special type of diffuse metastasis of carcinoma in the lymphatic vessels of the lungs. Lymphangitic carcinomatosis is commonly observed in malignancies of the breast, lung, pancreas, colon and cervix as a strong marker for poor prognosis. Presenting with common respiratory symptoms, it may be easily misdiagnosed as other pulmonary interstitial diseases. Pulmonary lymphangitic carcinomatosis is a rare manifestation of metastatic gastric cancer. The presented case describes a patient with pulmonary lymphangitic carcinomatosis in the course of stomach cancer. The primary diagnosis was established based on the exclusion of other interstitial lung diseases, with the use of imaging techniques as well as biochemical, microbiological and cytological findings. The patient's general condition was very severe, rendering him bedridden and therefore not eligible for any treatment, including chemotherapy. He died suddenly before final verification of the diagnosis. Pulmonary lymphangitic carcinomatosis should be suspected in patients with advanced gastric cancer, presenting with symptoms and signs of respiratory disease. Imaging techniques are mostly helpful to establish the diagnosis.

This report presents a case of giant osteoma of the right frontal and ethmoidal sinus, nasolacrimal duct and orbit in a patient with history of trauma, investigated using the computed tomography technique. The epidemiology, aetiology, diagnostic methods and treatment of the paranasal sinus osteoma have been reported, as well as discussed with the recently published data pertaining to the subject. The advantages of using computed tomography for detailed diagnosis of morphological features of the pathological changes, as well as their precise localization, have also been presented.
