Neuroblastoma (NB) is the most frequently diagnosed neoplasm during infancy and its incidence declines within the first 3-5 years of life. It can be rarely diagnosed in adolescents and young adults. Adolescents have advanced stage of disease, higher frequency of uncommon metastatic sites such as lungs, and worse outcomes. Herein, we describe an unusual case of NB in a 17-year-old adolescent presented with lung metastasis at diagnosis. The patient was diagnosed with stage IV NB. Thorax high-resolution computed tomography (HRCT) scan revealed irregular septal thickening with ground glass opacity consistent with pulmonary parenchymal metastases...

INTRODUCTION: Amiodarone is often used in the suppression of tachyarrhythmias. One of the more serious adverse effects includes amiodarone pulmonary toxicity (APT). Several pulmonary diseases can manifest including interstitial pneumonitis, organizing pneumonia, acute respiratory distress syndrome, diffuse alveolar hemorrhage, pulmonary nodules or masses, and pleural effusion. Incidence of APT varies from 5-15% and is correlated to dosage, age of the patient, and preexisting lung disease...

Metastatic pulmonary calcification (MPC) is a rare pathological condition consisting of lung calcium salt deposits which commonly occurs in patients affected by chronic kidney disease probably for some abnormalities in calcium and phosphate metabolism. CT represents the technique of choice for detecting MPC findings including ground glass opacities and partially calcified nodules or consolidations. We present a case of MCP in a patient affected by hepato-renal autosomic-dominant polycystic disease; chest CT revealed extensive lobar-segmental parenchymal calcification with a peculiar cauliflower shape which we called "calcified cauliflower" sign...

Since 'radical lobectomy' was reported by Cahan in 1960, the standard surgical care for lung cancer has been lobectomy, in which units of the lobe are excised with their specific regional hilar and mediastinal lymphatics. However, pulmonary function-preserving limited resection for lung cancer has gradually become more prevalent in the late 20th century. In 1995, Ginsberg et al. conducted a randomized controlled trial in which limited resection (segmentectomy and wide-wedge resection) and lobectomy for stage I lung cancer were compared and reported that limited resection should not be applied to healthy patients with clinical stage IA lung cancer...

BACKGROUND: The prognosis of non-small cell lung cancer (NSCLC) presenting as a ground glass opacity (GGO) nodule is better than other types of lung cancer. The purpose of this study was to evaluate the necessity of mediastinal lymph node evaluation (MLE) in clinical N0 GGO-predominant NSCLC. METHODS: We conducted a retrospective chart review of 358 patients treated for clinical N0 NSCLC that was found by curative resection to be 3 cm or smaller in size. We analyzed clinicopathological findings and survival among three groups with either GGO-predominant or solid-predominant tumor: no mediastinal lymph node evaluation (NoMLE) group, mediastinal lymph node sampling (MLS) group, and mediastinal lymph node dissection (MLND) group...

BACKGROUND: Ground glass opacity (GGO) generally associated with the lepidic component of lung adenocarcinoma. However, in some cases, GGO nodules have been associated with invasive adenocarcinomas, where a lepidic component is minimal or absent. The purpose of this study is to evaluate the clinicopathological characteristics and prognosis of non-lepidic invasive adenocarcinoma presenting as GGO nodules. METHODS: We reviewed computed tomography (CT) images from 168 patients diagnosed with non-lepidic invasive adenocarcinoma classified as stage T1N0M0 (≤3 cm) who underwent curative anatomical resection...

Eosinophilic lung diseases encompass a broad range of conditions wherein patients present with pulmonary opacities and eosinophilia of the serum, pulmonary tissue, or bronchoalveolar lavage fluid. Many of these entities can be idiopathic or are secondary to parasitic infection, exposure to drugs, toxins, or radiation. These diseases exhibit a wide range of imaging findings, including consolidation, ground-glass opacities, nodules, and masses. Diagnoses often require bronchoalveolar lavage and/or biopsy to confirm respiratory eosinophilia and to exclude other entities, such as infection or malignancy...

Primary pulmonary angiosarcoma (PPA) is a rare tumour arising from arterial or venous pulmonary vessels of various size. It is characterized by aggressive course and poor prognosis. The early diagnosis is difficult due to diverse clinical and radiological manifestations. We present a case report of 70 year-old man, active cigarette-smoker, with a 2-month history of non-massive hemoptysis. The thorax CT revealed several solid pulmonary nodules surrounded by areas of ground glass opacity. As bronchoscopy failed to deliver adequate tissue samples, video assisted thoracic surgery (VATS) with pleura and lung biopsy was necessary...

INTRODUCTION: Inhomogeneity of lung attenuation pattern is observed in high resolution chest computed tomography (HRCT) in some IPAH patients despite lack of interstitial lung disease. Such radiological changes are described either as ill-defined centrilobular nodules (CN) or as focal ground glass opacities (FGGO). There is no consensus in the literature, whether they indicate the distinct type of IPAH, or pulmonary venoocclusive disease (PVOD) with subtle radiological changes. Thus the aim of the present pilot study was to assess the frequency and clinical significance of inhomogenic lung attenuation pattern in IPAH...
