Primary lung lymphoma (PLL) is a rare type of lymphoma confined to the lung at the time of diagnosis. Pulmonary diffuse large B cells lymphoma (P-DLBCL) is the second most common type of PLL and it usually appears radiologically as solitary or multiple nodules or areas of consolidation. We present the case of a 63-year-old Caucasian male who developed severe acute respiratory failure and diffuse ground glass opacities (GGO) on chest computerized tomography. Diffuse GGO may be the radiological expression of very different diseases, ranging from infectious processes to interstitial lung diseases (ILDs) and neoplastic diseases...

BACKGROUND: Human pulmonary dirofilariasis is a rare zoonosis caused by the dog worm Dirofilaria spp., a parasite transmitted by mosquitos and resulting in peripheral lung nodules. The filarial nematode enters the subcutaneous tissue, travels to the right ventricle and dies causing a small pulmonary infarction that may embolize through the pulmonary vessels and may appear as a solitary nodule. These nodules are usually incidentally identified in asymptomatic patients undergoing chest imaging studies, and are generally interpreted to be malignant...

We report a case of 65-year male patient, a known hypertensive and a chronic smoker, who presented to the Civil Hospital, Karachi with complaints of cough, hemoptysis and shortness of breath for three weeks. The chest radiograph showed left apical solitary pulmonary nodule (SPN) and aneurysmal dilatation of the descending thoracic aorta. He was further investigated with contrast enhanced computed tomography (CECT) scan of chest, which apart from demonstrating malignant pulmonary lesion, surprisingly revealed Stanford type B descending thoracic aortic dissecting aneurysm with intramural hematoma, jeopardising renal and splanchnic circulation...

Chronic expanding hematoma (CEH) is a rare disease that is usually present as a large solitary pulmonary nodule. CEHs are slow growing, but processes underlying their development remain unknown. The present study herein reports the case of a 76-year-old male patient with CEH and discusses a number of CEH cases published in the literature. The majority of these previously described patients were Asians. The CEH in the present case was not a successfully resected one, but the patient's clinical course provided information concerning the natural history of the disease...

Applications of positron emission tomography/computed tomography (PET/CT) in the thorax include the evaluation of solitary pulmonary nodules, staging and restaging of oncologic patients, assessment of therapeutic response, and detection of residual or recurrent disease. Accurate interpretation of PET/CT requires knowledge of the physiological distribution of [18F]-fluoro-2-deoxy-D-glucose, as well as artifacts and quantitative errors due to the use of CT for attenuation correction of the PET scan. Potential pitfalls include malignancies that are PET negative and benign conditions that are PET positive...

Clear cell tumor of the lung is a rare benign mesenchymal tumor and only sporadic cases have been previously reported. The present study reports the case of a 58-year-old man who presented with an incidentally detected solitary pulmonary nodule. Based on comparisons with serial previous chest and spine radiographs, a growth pattern change in the nodule (initial gradual growth over 4.5 years, then recent no growth over 2.5 years) was identified. The nodule was diagnosed as a benign clear cell tumor of the lung (CCTL) following surgical resection...

Long Jiang, Jianxing He
Following the development of radiological technology, there has been an increase in the number of pulmonary nodules found. The management of pulmonary nodules represents a specific challenge to thoracic surgeons. Pulmonary nodules are small, focal, rounded radiographic opacities that may be solitary or multiple. The definite histopathologic diagnosis is crucial in determining management ranging from interval imaging to surgical resection. The choice of a particular biopsy technique depends on the risks/benefits of the procedure, the diagnostic yield, and local expertise...

Pulmonary nodules are often detected during the clinical course of several diseases or through routine screening. Various guidelines have proposed management algorithms for suspicious solitary nodules in lung cancer. Generally, solitary pulmonary nodules are managed according to nodule appearance and risk of lung cancer using low-dose, thin section computed tomography (CT). Liquid biopsy is promising for diagnosis, therapeutic-monitoring and follow-up in lung cancer; however, diagnosis and management pathways based on genetic examination alone have not been established...

Background: The differentiation of benign and malignant solitary pulmonary nodules (SPNs), especially subsolid nodules, is still challenging because of the small size, slow growth, and atypical imaging characteristics of these nodules. We aimed to determine the significance of mass growth rate (MGR) and mass doubling time (MDT) at follow-up CT of malignant SPNs. Methods: This retrospective study included 167 patients (169 SPNs, diameter 8-30 mm). Among the 169 SPNs, 114 malignant SPNs were classified into three types: pure ground-glass nodules (pGGNs), part-solid nodules (pSNs), and solid nodules (SNs)...

We report a case of an atypical pulmonary carcinoid with high serum ProGRP. A 78-year-old man was found to have an abnormal shadow by a chest X-ray. Chest computed tomography (CT) revealed a solitary pulmonary nodule in the right middle lobe, which was homogeneous, well demarcated, and round. The level of serum ProGRP was elevated to 104.6 pg/ml (normal<81 pg/ml). The nodule was suspected to be a pulmonary carcinoid tumor, and a right middle lobectomy with mediastinal lymph node dissection was performed...

PURPOSE: Diagnosis of solitary pulmonary nodule (SPN) is an important public health issue and 18 F-FDG PET/CT has proven to be more effective than CT alone. Pre-test risk stratification and clinical presentation of SPN could affect the diagnostic strategy. A relevant issue is whether thoracic segmental (s)-PET/CT could be implemented in patients with SPN. This retrospective multicenter study compared the results of FDG whole-body (wb)-PET/CT to those of s-PET/CT. METHODS: 18 F-FDG PET/CT of 502 patients, stratified for pre-test cancer risk, were retrospectively analyzed...
