A 21-year-old female patient presented with pneumonia and on chest roentgenogram a solitary pulmonary nodule was incidentally found. After an observation period she underwent left upper lobectomy because of documented tumor growth. Pathology showed an intrapulmonary glomus tumor of the proper type, which is a very rare occurrence. Literature review revealed only 11 published cases of this subty...
Clear cell tumor of the lung is a rare and very unusual benign pulmonary tumor. As clear cell tumor of the lung contains abundant cytoplasmic glycogen, this tumor is called "sugar tumor". We report a case of sugar tumor in a 64-yr-old man presenting as a round pulmonary nodule. On dynamic computed tomography (CT) scans, the solitary pulmonary nodule showed early wash-in enhancement with an earl...
Computer software was designed for classifying solitary pulmonary nodules (SPNs) into benign and malignant from their CT images, using image analysis methods. The system made use of three features, computed from the CT density matrix of the SPN, and a class-discriminating algorithm. System evaluation was performed on 51 histologically confirmed SPNs of indeterminate CT diagnosis. Overall classi...
We report a 74-year-old woman with cervical cancer who developed pulmonary cryptococcosis which presented as a solitary focal ground-glass opacity (GGO) on high-resolution computed tomography (HRCT). Serial HRCT showed the progression from the GGO to a discrete solid nodule. We hypothesize that the initial GGO may correspond pathologically to partial filling of air spaces with cryptococcal orga...
A solitary pulmonary nodule is defined as radiographic lesion with diameters no more than 3 cm and completely surrounded by normal lung tissue. It is commonly encountered in clinical practice and its diagnosis is a big challenge. Medical imaging, as a non-invasive approach, plays a crucial role in the diagnosis of solitary pulmonary nodules since the potential morbidity of surgery and the limit...
