Comparison between the ATS/ERS/JRS/ALAT criteria of 2011 and 2018 for Usual Interstitial Pneumonia on HRCT: a cross-sectional study.

Objectives: To determine whether the revised 2018 ATS/ERS/JRS/ALAT radiological criteria for usual interstitial pneumonia (UIP) provide better diagnostic agreement compared to the 2011 guidelines.

Methods: Cohort for this cross-sectional study (single center, nonacademic) was recruited from a multidisciplinary team discussion (MDD) from July 2010 until November 2018, with clinical suspicion of fibrosing interstitial lung disease (= 325). Exclusion criteria were technical HRCT issues, known connective tissue disease (rheumatoid arthritis, systemic sclerosis, poly-or dermatomyositis), exposure to pulmonary toxins or lack of working diagnosis after MDD.

Sarcomatous degeneration in fibrous dysplasia of the rib cage.

Malignant degeneration in fibrous dysplasia is a rare occurrence. Most cases are reported in polyostotic fibrous dysplasia with predisposition of the femur, tibia, maxilla, and mandible. The most commonly observed malignant tumors are osteosarcoma, fibrosarcoma, and chondrosarcoma.

Case report: inadvertent intrathecal placement of a pulmonary artery catheter introducer.

We present a case of unintended intrathecal cannulation by a pulmonary artery catheter introducer in a patient scheduled for coronary surgery. This complication was likely due to multiple attempts of placing the guidewire. Switching to the straight tip of the guidewire may have created a false route, facilitating entrance in the subarachnoid space.

Testicular sarcoidosis.

We describe a very unusual form of sarcoidosis of the testis, mimicking malignancy at initial presentation. Genitourinary sarcoidosis is rare and this case report emphasizes the importance of meticulous analysis of the patient's clinical history combined with imaging findings and specific pathological criteria to diagnose this granulomatous disorder.

Magnetic resonance imaging in teenagers and young adults with limited haemophilic arthropathy: baseline results from a prospective study.

The clinical relevance of subtle changes on magnetic resonance imaging (MRI) for evaluating haemophilia treatment is unknown. To determine the relationship of findings on MRI with joint function and bleeding in joints with apparently very mild arthropathy, a prospective study was performed. Knees and ankles of 26 patients, 13-26 years, were scanned.

Ultrasound demonstration of Struthers' ligament.

The supracondylar process is a bony spur at the anteromedial surface of the distal humerus. It is associated with the Struthers' ligament, running from its apex to the medial epicondyle. Symptoms may occur due to fracture and entrapment of nerves (most frequently the median nerve) and/or blood vessels underneath the structures.

Appendicitis in an obturator hernia.

We present a case of a 79-year-old female with a history of pain at the right groin for 9 days. Computer tomography of the pelvis showed herniation of the appendix through the obturator canal with a huge abscess surrounding the right hip joint. Laparotomy was performed and histopathology confirmed a perforated necrotic tip of the herniated appendix.

Brodie's abscess revisited.

Radiology plays an important role in the diagnosis of a Brodie's abscess, as can be difficult for a clinician to identify the disease using clinical information alone. A Brodie's abscess is clinically difficult to diagnose because patients typically have mild local symptoms, few or no constitutional symptoms, and near normal laboratory values. Furthermore, a Brodie's abscess may mimic various benign and malignant conditions, resulting in delayed diagnosis and treatment.

Imaging findings of a subcutaneous angioleiomyoma.

Angioleiomyoma is a benign smooth muscle tumor arising from the vessel walls.The tumor can occur anywhere in the body, but is most often seen in the extremities, particularly in the lower leg. The most common presentation is a solitary subcutaneous nodular lesion, which is either painful or painless.

MR arthrography of the hip joint: a practical approach.

This paper briefly reviews the technique of direct MR arthrography, MR anatomy and pathologic conditions of the acetabular labrum. Normal variants that may simulate pathology are also illustrated.
