PURPOSE: To evaluate serial computed tomography (CT) findings of pulmonary mucormycosis correlated with peripheral blood absolute neutrophil count (ANC). MATERIALS AND METHODS: Between February 1997 and June 2016, 20 immunocompromised patients (10 males, 10 females; mean age, 48.9 years) were histopathologically diagnosed as pulmonary mucormycosis. On initial (n=20) and follow-up (n=15) CT scans, the patterns of lung abnormalities and their changing features on follow-up scans were evaluated, and the pattern changes were correlated with ANC changes...

Skull metastasis from lung cancer is relatively common, yet the first presentation for this malignant disease is a rare occurrence. We herein report a case of a 54-year-old female, who had a good outcome following Whipple procedure for periampullary adenocarcinoma five years before her current presentation. During a routine follow-up, she was found to have a slowly progressive painless right parietal swelling. The systemic screening workup revealed no abdominal disease, but a solitary pulmonary nodule was identified...

In this report, we discuss an unusual case of pulmonary lymphomatoid granulomatosis (LYG), a rare form of angiocentric and angiodestructive lymphoproliferative disorder. This disease is thought to be caused by Epstein-Barr virus-induced lymphoproliferation. A 39-year-old male with no signi ficant past medical history presented with flu-like symptoms. Upon further evaluation, laboratory studies noted pancytopenia, and a chest X-ray showed bilateral nodular densities. A computerized tomography (CT) scan demonstrated bilateral pulmonary nodules and splenomegaly...

PURPOSE: CT-guided percutaneous transthoracic lung needle biopsy (PLB) is an effective procedure for obtaining cyto-histological diagnoses of peripheral lesions. However, upper postero-lateral lung nodules (UPLN) may be difficult to reach using a standard intercostal either anterior or lateral approach or when the nodule is just behind a rib or scapula. We evaluated the feasibility and effectiveness of trans-scapular approach (tPLB) in these patients using large-core needles. METHODS: We retrospectively collected the data of 11 consecutive patients (mean age 74...

INTRODUCTION: Since the National Lung Screening Trial demonstrated the utility of low-dose computed tomography screening for lung cancer, the detection rate of ground-glass nodules (GGNs) has increased. Endobronchial ultrasound with a guide sheath (EBUS-GS) is widely performed to diagnose peripheral pulmonary lesions, but there are not enough reports on the predictive ability of EBUS-GS in diagnosing GGNs. The aim of this study is to investigate the predictive factors for a successful diagnostic bronchoscopy for GGNs...

Globally, lung cancer remains the leading cause of cancer-related death. Annual low-dose computed tomography has been recommended as a screening test for early detection of lung cancers. Implementing this screening strategy is expected to challenge pulmonologist to confirm the nature of the increasing number of detected pulmonary nodules. Clinicians are obliged to use the less invasive and most efficient and safe means to set diagnoses. Hence, the field of diagnostic modalities, especially the advanced diagnostic bronchoscopy is witnessing rapid evolution to fulfill these unmet needs...

Malignant feminizing adrenocortical tumors are exceedingly rare. Their main presentation is gynecomastia. In these estrogen secreting tumors (with or without other adrenocortical hormones) lack of gynecomastia is exceptional as in our case. A 44-year-old man presented with abdominal pain. Radiological assessment revealed a tumor measuring 120 × 95 mm in the retroperitoneal area with numerous metastases. Pathological examination pleaded for an adrenal origin with a Weiss's score of 5. Six months later, the tumor relapsed, and he had a second surgery and was sent for hormone assessment...

Granulomatous lung diseases are a heterogeneous group of disorders that have a wide spectrum of pathologies with variable clinical manifestations and outcomes. Precise clinical evaluation, laboratory testing, pulmonary function testing, radiological imaging including high-resolution computed tomography and often histopathological assessment contribute to make a confident diagnosis of granulomatous lung diseases. Differential diagnosis is challenging, and includes both infectious (mycobacteria and fungi) and noninfectious lung diseases (sarcoidosis, necrotising sarcoid granulomatosis, hypersensitivity pneumonitis, hot tub lung, berylliosis, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, rheumatoid nodules, talc granulomatosis, Langerhans cell histiocytosis and bronchocentric granulomatosis)...

We describe the case of a 33-year-old man, a chronic user of powder cocaine, who presented with dyspnea, fever, night sweats, and significant weight loss. Chest HRCT revealed centrilobular nodules, giving an initial impression of miliary tuberculosis. Therefore, he was started on an empirical, four-drug antituberculosis treatment regimen. Four weeks later, despite the tuberculosis treatment, he continued to have the same symptoms. We then performed transbronchial lung biopsy. Histopathological analysis of the biopsy sample revealed birefringent foreign body granuloma...

Pulmonary surfactant protein A (SP‑A) and pulmonary surfactant protein D (SP‑D) are associated with the pathogenesis of chronic obstructive pulmonary disease (COPD). The aim of the present study was to determine the correlation between SP‑A, SP‑D and lung function in patients with COPD. A total of 60 patients with lung cancer undergoing unilateral lobectomy were selected and divided into three groups, including a non‑COPD group (n=20), a COPD treatment group (n=20) and a COPD control group (n=20)...

Liposarcomas are rare malignant tumors showing adipocytic differentiation. We report a well-differentiated liposarcoma in a 6-y-old, male neutered cat with a prominent inflammatory component and metastatic spread to the lungs. The patient was initially presented because of fever, lethargy, and a firm subcutaneous inguinal mass. A Tru-cut biopsy of the mass revealed a mixture of well-differentiated adipocytes and lymphoplasmacytic-histiocytic inflammation, interpreted as panniculitis. The mass was surgically excised but recurred 4 mo later...

BACKGROUND: Clinical prediction models and 18F-FDG-PET/CT are used for assessment of solitary pulmonary nodules (SPNs) however biopsy is still required before treatment which carries risk. AIM: To determine combined predictive benefit of one such model combined with modern PET/CT data to improve decision making about biopsy prior to treatment and possibly reduce costs. METHOD: Patients with a SPN undergoing 18F-FDG-PET/CT from January 2011-December 2012 were retrospectively identified...

PURPOSE: Positron-emission tomography can be useful in oncology for diagnosis, (re)staging, determining prognosis, and response assessment. However, partial-volume effects hamper accurate quantification of lesions <2-3× the PET system's spatial resolution, and the clinical impact of this is not evident. This systematic review provides an up-to-date overview of studies investigating the impact of partial-volume correction (PVC) in oncological PET studies. METHODS: We searched in PubMed and Embase databases according to the PRISMA statement, including studies from inception till May 9, 2016...
