Co-existent Epicardial Paraganglioma and Anterior Mediastinal Thymoma.

J Radiol Case Rep 2020 Oct 31;14(10):16-30. Epub 2020 Oct 31.

Department of Cardiovascular/Thoracic Surgery, Mayo Clinic, Jacksonville, FL, USA.

Thymoma and paraganglioma are known causes of mediastinal masses, the latter being extremely rare. Thymomas arise from remnant thymic tissue in the anterior mediastinum; whereas, thoracic paragangliomas arise from para-aortic or para-vertebral sympathetic chain ganglion (derivatives of embryonic neural crest) in the middle or posterior mediastinum. We report a case of a middle-aged woman with two mediastinal masses, originally believed to be a single tumor or primary malignancy with adjacent metastasis on Computed Tomography (CT) that were further delineated with Magnetic Resonance Imaging (MRI) and [68Ga]-DOTA-(Tyr3)-octreotate (DOTA-TATE) Positron Emission Tomography-Computed Tomography (PET-CT) and surgical pathology as two distinct entities: left epicardial paraganglioma and anterior mediastinal thymoma.

BMJ Case Rep 2021 Jan 28;14(1). Epub 2021 Jan 28.

Dermatology, Hospital Vall d'Hebron, Barcelona, Spain.

Drug-induced sarcoidosis-like reactions (DISRs) are systemic granulomatous diseases that develop in the context of a new drug onset. Ipilimumab is an immune checkpoint inhibitor (ICI) approved for the treatment of advanced melanoma which has been associated with DISR. Differential diagnosis between tumour progression and DISR by positron emission tomography/computed tomography (PET/CT) in patients treated with an ICI can be a challenge. Read More

The role of radiological imaging for masses in the prevascular mediastinum in clinical practice.

J Thorac Dis 2020 Dec;12(12):7591-7597

Department of Diagnostic, Interventional and Pediatric Radiology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland.

Tumors in the prevascular compartment of the mediastinum are rare and imaging plays a major role in their detection, (differential) diagnosis, staging, and follow-up. The prevascular compartment is bordered anteriorly by the posterior aspect of the sternum, posteriorly by the ventral aspect of the pericardium, cranially by the thoracic outlet, and caudally by the diaphragm. In many cases, the diagnosis of a lesion in the prevascular compartment is an incidental finding either on chest radiograph (CR) or on computed tomography (CT) scans. Read More

Mediastinal teratoma presenting as a cervical tumor: images.

Indian J Thorac Cardiovasc Surg 2020 Sep 10;36(5):552-554. Epub 2020 Jul 10.

The Department of CTVS, CMC Hospital, The Christian Medical College, Vellore, Tamil Nadu 632004 India.

Benign extra-gonadal germ cell tumors, known as teratoma or dermoid cysts, are commonly found in the anterior mediastinum in association with the thymic gland. This association is due to their common site of embryological origins, from the third and the fourth pharyngeal pouches. Since it is not unusual to find normal thymic tissue in the neck, germ cell tumors arising from here will present as a cervical tumor. Read More

Germ cell tumors and associated hematologic malignancies evolve from a common shared precursor.

J Clin Invest 2020 12;130(12):6668-6676

Human Oncology and Pathogenesis Program, Memorial Sloan Kettering Cancer Center, New York, New York, USA.

Germ cell tumors (GCTs) are the most common cancer in men between the ages of 15 and 40. Although most patients are cured, those with disease arising in the mediastinum have distinctly poor outcomes. One in every 17 patients with primary mediastinal nonseminomatous GCTs develop an incurable hematologic malignancy and prior data intriguingly suggest a clonal relationship exists between hematologic malignancies and GCTs in these cases.

Long-term results of suppressing thyroid-stimulating hormone during radiotherapy to prevent primary hypothyroidism in medulloblastoma/PNET and Hodgkin lymphoma: a prospective cohort study.

Front Med 2021 Feb 13;15(1):101-107. Epub 2020 Aug 13.

Pediatric Oncology Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, 20146, Italy.

Primary hypothyroidism commonly occurs after radiotherapy (RT), and coincides with increased circulating thyroid-stimulating hormone (TSH) levels.We tested therefore the protective effect of suppressing TSH with L-thyroxine during RT for medulloblastoma/PNET and Hodgkin lymphoma (HL) in a prospective cohort study. From1998 to 2001, a total of 37 euthyroid children with medulloblastoma/PNET plus 14 with HL, scheduled for craniospinal irradiation and mediastinum/neck radiotherapy, respectively, underwent thyroid ultrasound and free triiodothyronine (FT3), free thyroxine (FT4), and TSH evaluation at the beginning and end of craniospinal iiradiation.
