Imaging of thoracic tuberculosis: pulmonary and extrapulmonary.

Tuberculosis (TB) remains the leading cause of death from a single infectious agent globally, despite being a potentially curable disease. This disease typically affects the lungs but may involve many extrapulmonary sites, especially in patients with risk factors such as HIV infection. The clinical features of extrapulmonary TB may mimic many different disease entities, particularly at less common thoracic sites such as the heart, chest wall, and breast.

Imaging of supra-thoracic tuberculosis.

Tuberculosis (TB) typically affects the lungs, but may involve many extra-pulmonary sites; with the latter especially prone in patients with human immunodeficiency virus infection. The clinical features of extra-pulmonary TB are often non-specific, mimicking many different disease entities. Application of the most appropriate imaging modality and knowing the imaging findings with clinical context awareness help initiation of further investigations, diagnosis and early treatment.

Imaging of infra-thoracic tuberculosis.

Tuberculosis (TB) is a potentially curable disease that is a leading cause of death globally. While it typically affects the lungs, this disease may involve many extra-pulmonary sites, particularly in patients with risk factors. Extra-pulmonary TB often mimics a variety of different diseases, posing a diagnostic dilemma.

Imaging of musculoskeletal tuberculosis.

Extra-pulmonary tuberculosis (TB) of the musculoskeletal system usually manifests with non-specific clinical features, mimicking a variety of diseases. Diagnosis and treatment of spinal and extra-spinal musculoskeletal TB are often challenging. Imaging has an important role in detecting this disease, aiding diagnosis, identifying complications, and monitoring disease progression.

Imaging of musculoskeletal tuberculosis.

Tuberculosis (TB) represents a major public health problem worldwide. Any tissue may be infected. Involvement of the musculoskeletal (MSK) system account for 1-3% of all tuberculous infections.

Early Identification of Sacroiliitis in Patients with Suspected Spondyloarthritis: A Challenging Task.

Objective: The purpose of this study was to assess the performance of computed tomography (CT) scan and magnetic resonance imaging (MRI) for detecting sacroiliitis in nonradiographic SpA (nr-SpA).

Methods: This cross-sectional monocentric double-blind study included 63 patients consulting for symptoms suggestive of SpA between February 2014 and February 2017. Patients with conventional radiographs showing a confirmed sacroiliitis (grade 3 or 4) were not included.

Unusual bone localization of sarcoidosis mimicking metastatic lesions: case report and review of literature.

Sarcoidosis is a multisystem disease of unknown origin. Diagnosis remains challenging, based on organ site involvement, histological confirmation of non-caseating granuloma and an appropriate clinical syndrome. Granulomatous bone involvement is rare and may be ignored because it is usually asymptomatic.

Performances of single tube nested polymerase chain reaction and GeneXpert ultra on Formalin fixed paraffin embedded tissues in the diagnosis of tuberculous spondylodiscitis.

Introduction: Tuberculous Spondylodiscitis is the most common form of musculoskeletal tuberculosis. Molecular techniques on fresh tissues are proved to improve the diagnosis of tuberculous spondylodiscitis and to allow a rapid diagnosis to initiate the treatment and prevent neurological complications.

Objectives: The objective of the present study was to assess the diagnostic performances of single tube nested PCR and GeneXpert ultra in the diagnosis of tuberculous spondylodiscitis on formalin fixed paraffin embedded tissues.

Brucellar spondylodiscitis: A case series with focus on histopathological features.

Brucellar spondylodiscitis (BS) is the most common form of musculoskeletal brucellosis. The isolation of Brucella spp from blood, other body fluids or tissue cultures is the gold standard for definitive diagnosis of BS. BS shows a large histopathological spectrum of lesions with non-specific and granulomatous forms, and its histopathological features are not widely reported.

The Value of Histology in the Diagnosis of Tuberculous Spondylodiscitis.

Background: Tuberculous spondylodiscitis (TS) is the most common form of musculoskeletal tuberculosis. Currently, histology is widely used to distinguish tuberculous from nontuberculous disease.

Objectives: The aim of the present study was to assess the accuracy of histology compared with bacteriology in the diagnosis of TS.

Skeletal fluorosis: don't miss the diagnosis!

Skeletal fluorosis is a rare toxic osteopathy characterized by massive bone fixation of fluoride. The disease occurs as an endemic problem in some parts of the world and is the result of prolonged ingestion or rarely by inhalation of high amounts of fluoride. Radiographic presentation is mainly characterized by bone changes with osteocondensation and later ossification of many ligaments and interosseous membranes.

Granulomatous spondylodiscitis: A case series with focus on histopathological features.

To report a series of Granulomatous Spondylodiscitis (GS) with focus on the histopathological features of the different forms of GS. Case series. Pathology department of Charles Nicolle's Hospital of Tunisia This study included 57 patients diagnosed with GS.

Chronic arthritis revealing sarcoidosis in a patient exposed to silica.

Sarcoidosis is a systematic, granulomatous disease of unknown cause which can affect any organ in the body. Pulmonary involvement is the most common. Musculoskeletal manifestations of sarcoidosis are less common affecting 10-25% of patients and chronic arthritis occurs rarely.

Uncommon etiology of knee pain: Lipoma arborescens.

Unlabelled:  Lipoma arborescens is a rare intra-articular benign tumor. It affects mostly the knee and the diagnosis is usually difficult due to resembling symptomatology of osteoarthritis.

Cases Presentation: We report herein 3 new cases of lipoma arborescens of the knee in which a patient has synovitis associated.

Traumatic Meniscus and Cruciate Ligament Tears in Young Patients: A Comparison of 3T Versus 1.5T MRI.

Objective: To compare diagnosis value of 1.5T and 3T MRI in the detection of traumatic knee injuries in young patients by reference to arthroscopy.

Materials And Methods: One hundred patients were prospectively included.

[The value of MRI in the diagnosis of joint involvement in malignant primitive tumors of the knee].

Introduction: Surgical treatment of malignant primitive tumors of bone needs a precise preoperative assessment of tumor local extension. Joint involvement (JI) represents the most important finding to determine, for the choice of surgical procedure (intra- or extra-articular resection).

Objective: To determine the value of different MR signs for the diagnosis of joint involvement in malignant primitive tumors of the knee.

Assessment of preclinical atherosclerosis in patients with ankylosing spondylitis.

Objective: Epidemiological studies recently confirmed the increased risk of vascular morbidity and mortality during ankylosing spondylitis (AS). Increase of intima-media thickness (IMT) of the common carotid artery is a useful and noninvasive marker of preclinical atherosclerosis. The aim of our study was to compare IMT in patients with AS with matched controls and to determine risk factors of atherosclerosis related to AS.

Performance of ultrasounds compared with radiographs to detect chronic enthesitis signs in patients with ankylosing spondylitis.

To assess the performance of ultrasound in detecting erosion, swelling, and new bone comparing to radiographs in five lower limb entheses in patients with ankylosing spondylitis (AS). Prospective study of 60 patients meeting modified New York criteria for AS. Lateral radiographs of both knees and ankles followed by a high-resolution Doppler ultrasound examination with a high-frequency (15 MHz) linear probe were performed.

Objectives: To look for correlations among clinical, radiographic, and sonographic scores for enthesitis in patients with ankylosing spondylitis (AS).

Methods: Prospective study of 60 patients meeting modified New York criteria for AS. The clinical evaluation relied on the BASDAI, BASFI, and ASQoL and on a visual analog scale (VAS) for entheseal pain, as well as on two specific enthesitis indices, the Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) and the Spondyloarthritis Research Consortium of Canada Enthesitis Index (SPARCC).
