Structured reporting for fibrosing lung disease: a model shared by radiologist and pulmonologist.

OBJECTIVES: To apply the Delphi exercise with iterative involvement of radiologists and pulmonologists with the aim of defining a structured reporting template for high-resolution computed tomography (HRCT) of patients with fibrosing lung disease (FLD). METHODS: The writing committee selected the HRCT criteria-the Delphi items-for rating from both radiology panelists (RP) and pulmonology panelists (PP). The Delphi items were first rated by RPs as "essential", "optional", or "not relevant". The items rated "essential" by < 80% of the RP were selected for the PP rating. The format of reporting was rated by both RP and PP. RESULTS: A total of 42 RPs and 12 PPs participated to the survey. In both Delphi round 1 and 2, 10/27 (37.7%) items were rated "essential" by more than 80% of RP. The remaining 17/27 (63.3%) items were rated by the PP in round 3, with 2/17 items (11.7%) rated "essential" by the PP. PP proposed additional items for conclusion domain, which were rated by RPs in the fourth round. Poor consensus was observed for the format of reporting. CONCLUSIONS: This study provides a template for structured report of FLD that features essential items as agreed by expert thoracic radiologists and pulmonologists.

Left-Sided Upper Partial Anomalous Pulmonary Venous Return through a Curved Vein Joining the Left Brachiocephalic Vein.

The evaluation of pulmonary veins during cross-sectional imaging of the chest and the knowledge of their embryology and anatomy are useful for detecting congenital conditions that may be clinically significant. Moreover, with the spread of cross-sectional imaging it is very frequent to find anatomical variants; therefore the radiologist should easily recognize their appearances. This case report shows a left-side upper partial anomalous pulmonary venous return (PAPVR) through a "curved" vein that joins the left brachiocephalic vein, in a female patient who underwent whole-body computed tomography (CT) for staging endometrial cancer. This was an incidental finding, not related to any symptoms; however, we explain the anatomical aspects of this abnormality within the congenital condition of PAPVR and its possible clinical relevance.

Rapid tumor shrinkage with lapatinib plus capecitabine in a patient with massive liver involvement.

We present the case of a 58-year-old woman with breast cancer metastasizing to the liver after adjuvant chemotherapy. A liver biopsy confirmed metastatic lesions from breast cancer that were immunohistochemically positive for estrogen/progesterone receptors and HER2. After first-line treatment with trastuzumab and vinorelbine, the patient commenced therapy with capecitabine (1000 mg/m2 twice daily, days 1-14) and lapatinib (1250 mg/day). Three months after the administration of this combination therapy, the liver metastases had shrunk substantially. Lapatinib may have the potential to convert trastuzumab-refractory tumors to trastuzumab-sensitive tumors in HER2-positive breast cancer by upregulation of the cell surface expression of HER2. Further study will be needed to evaluate in the clinic the combination of lapatinib and an m-TOR inhibitor as a treatment approach in HER2 overexpressing breast cancer that shows a poor response to trastuzumab.

Recurrent pulmonary embolism due to echinococcosis secondary to hepatic surgery for hydatid cysts.

We describe the case of a 53-year-old man with recurrent pulmonary embolism due to intra-arterial cysts from Echinococcus. Both the patient's medical history and the computed tomographic (CT) scan abnormalities led to the diagnosis. The CT scan, performed during hospitalization in our ward, showed cystic masses in the left main pulmonary artery and in the descending branch of the right pulmonary artery. Within cystic masses, thin septa were visible, giving a chambered appearance, which was suggestive of a group of daughter cysts. In the past, our patient underwent multiple operations for recurring echinococcal cysts of the liver. After the last intervention, 4 years earlier, his postoperative course was complicated by pulmonary embolism: a CT scan showed a filling defect in the descending branch of the right pulmonary artery, which was caused by the same cystic mass as 4 years later, although smaller. This mass, not properly treated, increased in diameter. Moreover, after 4 years, there has been a new episode of embolism, which involved the left main pulmonary artery. This is the first case in which there are repeated episodes of pulmonary embolism echinococcosis after hepatic surgery for removal of hydatid cysts.

[Pulmonary alveolar microlithiasis: clinical and radiological course of three cases according to conventional radiology and HRCT. A hypothesis for radiological classification].

Pulmonary alveolar microlithiasis (PAM) is a rare chronic disease of unknown etiology and pathogenesis. The disease is characterized by the diffuse presence in the alveoli of minute calcific deposits known as microliths. In most cases patients have mild clinical symptoms, contrasting with the severe radiographic appearance: this is a typical feature that should raise the suspicion of PAM. The first to describe the clinical and radiographic aspects of the disease, as well as the first case series, was the radiologist Sosman. In recent years, high resolution computed tomography (HRCT) has made it possible to define the extent and severity of the disease more precisely, and has demonstrated calcifications in anatomical sites that could not be shown by conventional radiology. The present paper describes the radiological evolution of the disease, and suggests a classification based on the radiographic and HRCT follow-up of the three clinical cases: two young patients followed up for 24 and 11 years and one elderly man who is still alive and is the PAM case with the longest survival since diagnosis, over 50 years, to be reported in the international literature.
