The urachus revisited: multimodal imaging of benign & malignant urachal pathology.

The urachus is a fibrous tube extending from the umbilicus to the anterosuperior bladder dome that usually obliterates at week 12 of gestation, becoming the median umbilical ligament. Urachal pathology occurs when there is incomplete obliteration of this channel during foetal development, resulting in the formation of a urachal cyst, patent urachus, urachal sinus or urachal diverticulum. Patients with persistent urachal remnants may be asymptomatic or present with lower abdominal or urinary tract symptoms and can develop complications.

Diagnostic accuracy of diffusion-weighted imaging- magnetic resonance imaging compared to positron emission tomography/computed tomography in evaluating and assessing pathological response to treatment in adult patients with lymphoma: A systematic review.

The use of Positron emission tomography/computerised tomography (PET/CT) is well established in the staging and assessment of treatment response of lymphoma. Recent studies have suggested that whole body diffusion-weighted imaging -magnetic resonance imaging (WB-DW-MRI) may be an alternative to PET/CT in both staging and assessment of treatment response. A systematic review was performed to assess the ability of DW-MRI in the assessment of treatment response in lymphoma.

Patterns of Disease in Patients with Middle-Lobe Predominant Bronchiectasis.

Background: Middle-lobe predominant bronchiectasis affecting the right middle-lobe and/or lingula (RMLP) is classically described in asthenic, elderly females with skeletal abnormalities or associated nontuberculous mycobacterial (NTM) infection.

Objectives: We aimed to evaluate the frequency and clinical characteristics of patients with an RMLP phenotype in a cohort of newly diagnosed bronchiectasis patients and determine associations with disease severity.

Methods: A retrospective observational cross-sectional cohort study of consecutive bronchiectasis patients in our institution was performed.

Overdiagnosis of Pulmonary Embolism by Pulmonary CT Angiography.

Objective: The purpose of this study is to evaluate the rate of overdiagnosis of pulmonary embolism (PE) by pulmonary CT angiography (CTA) in a tertiary-care university hospital.

Materials And Methods: This study is a retrospective review of all pulmonary CTA examinations performed in a tertiary-care university hospital over a 12-month period. Studies originally reported as positive for PE were retrospectively reinterpreted by three subspecialty chest radiologists with more than 10 years' experience.

Hiatal hernias are correlated with increased severity of non-cystic fibrosis bronchiectasis.

Background And Objective: Hiatal hernias (HH) are associated with gastro-oesophageal reflux and may contribute to lung disease severity. We aimed to evaluate the prevalence of HH among stable non-cystic fibrosis bronchiectasis (NCFB) patients and determine associations with disease severity.

Methods: A retrospective cross-sectional cohort study of 100 consecutive NCFB patients in our institution was performed.

Update in the evaluation of the solitary pulmonary nodule.

A solitary pulmonary nodule (SPN) is defined as a round opacity that is smaller than 3 cm. It may be solid or subsolid in attenuation. Semisolid nodules may have purely ground-glass attenuation or be partly solid (mixed solid and ground-glass attenuation).

A clue in a colour? EBUS-TBNA in the analysis of isolated mediastinal lymphadenopathy.

A 52-year-old female patient with a background history of malignant melanoma was referred to the interventional pulmonology unit at Galway University Hospital for the investigation of possible intrathoracic recurrence. A CT of the thorax (CT thorax) demonstrated mediastinal lymphadenopathy at position 4R, right paratracheal region. An endobronchial ultrasound (EBUS) revealed multiple enlarged lymph nodes at station 4R.

Multimodality imaging evaluation of esophageal cancer: staging, therapy assessment, and complications.

Esophageal cancer is among the leading causes of cancer-related deaths worldwide. The management of patients with esophageal cancer is determined to a large extent by patient performance status, location of the primary cancer, and stage of disease at presentation. Multimodality regimens combining neoadjuvant chemotherapy and/or radiotherapy followed by surgery have been increasingly used in suitable candidates with locally advanced cancer.

Solid pseudopapillary neoplasm of the pancreas.

Solid pseudopapillary neoplasms (SPNs) are rare entities accounting for between 0.13 and 2.7 per cent of pancreatic tumours.

Unsuspected pulmonary emboli in oncology patients undergoing routine computed tomography imaging.

Introduction: Clinically unsuspected pulmonary embolism (PE) can be detected in oncology patients undergoing computed tomography (CT) imaging for reasons other than for PE diagnosis, but there is little prospective data on its true prevalence, clinical importance, or on methods to improve detection.

Methods: In consecutive oncology patients undergoing CT imaging of the chest for indications other than PE detection, CT pulmonary angiography (CTPA) was systematically included as part of the imaging protocol. Each imaging study was prospectively analyzed for the presence of PE.

Clinical utility of PET/CT in lymphoma.

Objective: The purpose of this review is to assist interpreting radiologists in becoming familiar with the role of PET/CT in baseline staging and therapeutic response assessment in the management of lymphoma, in becoming aware of imaging pitfalls, and in understanding the natural behavior of lymphoma and the therapeutic options.

Conclusion: Therapeutic strategies for the management of lymphoma are constantly being refined to improve long-term survival with the lowest risk of toxicity to the patient. PET/CT is accurate for baseline staging and yields important prognostic information for determining the most appropriate initial treatment.

Imaging of pulmonary fusariosis in patients with hematologic malignancies.

Objective: The purpose of this study was to assess the radiographic features of pulmonary fusariosis, an increasingly encountered cause of severe opportunistic mold pneumonia.

Conclusion: Pulmonary fusariosis has radiographic manifestations that are suggestive of an angioinvasive mold. Nodules or masses were the most common findings at CT, seen in 82% of patients compared with only 45% on chest radiography.

Imaging of non-small cell lung cancer of the superior sulcus: part 2: initial staging and assessment of resectability and therapeutic response.

Imaging plays a crucial role in the diagnosis and staging of superior sulcus tumors, assessment of their resectability, determination of the optimal approach to disease management, and evaluation of the response to therapy. Computed tomography (CT), magnetic resonance (MR) imaging, and positron emission tomography (PET)/CT contribute important and complementary information. Whereas CT is optimal for depicting bone erosion and for staging of intrathoracic disease, MR imaging is superior for evaluating tumor extension to the intervertebral neural foramina, the spinal cord, and the brachial plexus, primarily because of the higher contrast resolution and multiplanar capability available with MR imaging technology.

Imaging of non-small cell lung cancer of the superior sulcus: part 1: anatomy, clinical manifestations, and management.

Non-small cell carcinomas of the superior pulmonary sulcus represent 3% of all lung cancers and are associated in most cases with a poor clinical outcome. Multimodality therapy with irradiation, chemotherapy, and surgery offers the best possibility for long-term survival and cure in most cases. For patients with pulmonary sulcus tumors that are not surgically resectable, chemoradiotherapy may help prolong survival and provide long-term pain relief.

PET/CT and hepatic radiation injury in esophageal cancer patients.

This paper evaluates the imaging appearance of radiation injury in the liver on positron emission tomography (PET)/computed tomography (CT) in patients with distal esophageal cancer who underwent pre-operative chemoradiation therapy. Twenty-six patients with distal esophageal cancer who received chemoradiotherapy before esophagectomy were included. All patients had baseline and follow-up PET/CT.
