IgG4-related disease (IgG4-RD) is a fibroinflammatory condition that can affect practically every organ. Although it was first identified in pancreas and salivary glands, major organs like liver, biliary tree, kidney, thyroid glands and lungs are commonly involved, sometimes resulting in organ failure. We describe a case of an 41-year-old man presented with back pain after a rotator cuff injury. A Computed Tomography (CT) revealed incidentally a right lower lobe paravertebral lesion extending across the T5 and T6 vertebral levels and invading into the adjacent pleural surface...

INTRODUCTION: Hodgkin lymphoma (HL) is a common lymphoid malignancy rarely associated with Guillain-Barré Syndrome (GBS). In most cases, GBS does not precede HL. METHODS: We describe a patient with acute inflammatory demyelinating polyneuropathy (AIDP) who fulfilled criteria for GBS that heralded undiagnosed HL. RESULTS: Cerebrospinal fluid (CSF) studies revealed albuminocytologic dissociation with significant protein elevation (250 mg/dL)...

BACKGROUND: During gestation, the primordial thymus migrates from the pharynx to the anterior mediastinum, thus thymic tissue can remain at any point along this path. Intrathyroidal thymic remnants are rare, and their sonographic patterns have only recently been described. This retrospective study presents the sonographic appearance of ectopic intrathyroidal thymus and emphasizes the role of sonography in order to avoid misdiagnosis. METHODS: The population consisted of 42 children, 3...

Primary pulmonary synovial sarcoma (PPSS) is a rare disease. Diagnosis is made postoperatively following resection of the tumor. We describe the case of a 39-year-old non-smoking woman whose chest imaging revealed a heterogeneous mass (5.4 cm × 4.6 cm), with soft tissue density in the right upper lobe and pleural effusion in the right hemithorax. The tumor was enhanced on a computed tomography scan, in which enlargement of the mediastinal lymph nodes compressing the adjacent superior vena cava was observed...

Primary pulmonary chondrosarcoma is a rare neoplasm that usually grows slowly, metastasizes late, and responds well to excision when localized. Herein, we present a 59-year-old man who manifested with hemoptysis, cough and dyspnea with a hemithorax mass. A chest computed tomography scan demonstrated a fast-growing mass in the right upper lobe, and the enhancement was partially heterogeneous. Bronchoscopy revealed a hemorrhagic neoplasm in the right upper bronchus. A bronchoscopy biopsy specimen revealed a variety of tissues, including mucoid cartilage, fibers, respiratory epithelium and squamous epithelium...

INTRODUCTION: Parathyroid crisis due to ectopic parathyroid adenomas can pose diagnostic and management challenges, since it is quite rare in clinical practice. CLINICAL FINDINGS/PATIENT CONCERNS: A 67-year-old Chinese male presented as a parathyroid crisis due to an ectopic mediastinal parathyroid adenoma with his serum calcium and PTH markedly increased in short time. An ultrasonography and computed tomography (CT) scan of the neck did not reveal any parathyroid adenoma...

When confronted with a metastatic poorly differentiated tumor of unknown origin, the initial workup includes the standard panel of immunostains to rule out carcinoma, sarcoma, lymphoma, and the greatest mimicker in pathology - malignant melanoma. Although not specific, the S-100 protein is expressed in over 95% of malignant melanomas. Herein, we present a case of multiorgan metastatic malignancy with a dominant hilar and mediastinal mass in a current smoker; clinically, highly suggestive of widespread primary lung cancer...

BACKGROUND: Neuroendocrine tumors of the thymus (NETT) constitute less than 5% of all anterior mediastinal masses but are aggressive and lead to poor overall survival. This study was designed to evaluate factors that influence the prognosis of patients with NETT and the role of surgical intervention in survival. METHODS: We analyzed the Surveillance, Epidemiology, and End Results cancer database to identify patients with NETT. We performed univariate and multivariate analyses to identify prognostic factors among demographic, tumor, and treatment variables...

Extrapulmonary tuberculosis refers to Mycobacterium tuberculosis involving organs other than the lungs (eg, pleura, lymph nodes, genitourinary tract, abdomen, skin, joints and bones, or meninges). In non-HIV-endemic areas, where reactivation is the predominant mechanism of tuberculosis, pleural involvement occurs in 4% of cases. We present an extremely rare case of a 62-year-old immunocompetent patient with pleural tuberculosis confirmed by surgical pleural biopsies, who presented with a large mediastinal mass and evidence of pulmonary artery invasion on CT scanning and endobronchial ultrasonography imaging, highlighting a unique and malignant-like character of the disease...

Sarcoidosis is a systemic inflammatory disorder characterized by non-caseating granulomas, predominantly involving lung, mediastinal lymph nodes and other organs. Synovium involvement is infrequent, and as far as we know, involvement of a periprosthetic membrane has not been reported in the English literature. Intra-articular diffuse tenosynovial giant cell tumor ("conventional diffuse pigmented villonodular synovitis") is an uncommon, locally aggressive neoplasm with few previous case reports in which it arose in periprosthetic tissues after knee arthroplasty...

INTRODUCTION: The mediastinal bronchogenic cysts represents 50%-60% of mediastinal cysts and rarely occurs in the posterior mediastinum. The final surgical resection is indicated for symptomatic patients and is recommended for some asymptomatic patients in order to establish the diagnosis and to avoid any subsequent complications. CASE PRESENTATION: We report a case of 17 years-old male suffering from bronchogenic cysts of the mediastinum. The patient was admitted to our hospital complaining with dry chough and dyspnea; CT scan showed a cystic mass in posterior mediastinum...

BACKGROUND: Small cell lung cancer (SCLC) commonly presents as hilar/mediastinal masses. In some occasions, conventional flexible bronchoscopy fails and a substantial amount of time is lost until establishing the diagnosis. OBJECTIVE: The aim of the study was to demonstrate the superiority of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) compared to conventional methods in establishing the diagnosis as an initial modality as well as to point out the saved time until the diagnosis...
