Society for Cardiovascular Magnetic Resonance 2021 cases of SCMR and COVID-19 case collection series.

The Society for Cardiovascular Magnetic Resonance (SCMR) is an international society focused on the research, education, and clinical application of cardiovascular magnetic resonance (CMR). "Cases of SCMR" is a case series hosted on the SCMR website ( https://www.scmr.org ) that demonstrates the utility and importance of CMR in the clinical diagnosis and management of cardiovascular disease. The COVID-19 Case Collection highlights the impact of coronavirus disease 2019 (COVID-19) on the heart as demonstrated on CMR. Each case in series consists of the clinical presentation and the role of CMR in diagnosis and guiding clinical management. The cases are all instructive and helpful in the approach to patient management. We present a digital archive of the 2021 Cases of SCMR and the 2020 and 2021 COVID-19 Case Collection series of nine cases as a means of further enhancing the education of those interested in CMR and as a means of more readily identifying these cases using a PubMed or similar literature search engine.

Cardiac Multimodality Imaging Assessment of Dystrophic Myocardial Calcification in a Human Immunodeficiency Virus-Infected Patient With Dilated Cardiomyopathy.

Dystrophic myocardial calcification represents the sequelae of local tissue damage and cellular necrosis. We present the case of a 72-year-old man who presented with exertional chest pain. He had a medical history of human immunodeficiency virus (HIV) infection and chronic dilated cardiomyopathy with severe left ventricular (LV) systolic dysfunction and wall motion abnormalities at the inferior and lateral LV walls. A cardiac magnetic resonance (CMR) examination from 16 years ago showed a subendocardial late gadolinium enhancement (LGE) distribution consistent with prior myocardial infarction (MI). Recently, a pharmacological stress myocardial perfusion imaging by CMR had been positive for myocardial ischemia in the left descending coronary artery (LAD) territory. A cardiac CT angiography (CCTA) showed non-significant LAD obstruction <50% consistent with microvascular ischemia and the presence of dystrophic myocardial calcification as an unusual progression of a prior MI. Conservative approach and optimal medical therapy were employed in our patient, and there was no symptom progression during the two-month follow-up period.

Recurrent Papillary Thyroid Carcinoma to the Cervical Lymph Nodes: Outcomes of Compartment-Oriented Lymph Node Resection.

INTRODUCTION: Recurrence of papillary thyroid carcinoma after initial treatment is challenging. Surgical reintervention is recommended, but cure after surgery in uncertain and surgical morbidity may be high. This study evaluates the effect of compartment-oriented lymph node dissection (LND) on clinical and biochemical cure rate as well as the related complications. PATIENTS AND METHODS: All patients who underwent LND for recurrent papillary thyroid carcinoma between 2000 and 2015 were included. Demography, the extent of the initial surgery, usage of 131I, the pattern of recurrence, diagnosis, details of the surgical reintervention, histological findings, surgical morbidity, and clinical and biochemical outcomes were analyzed. RESULTS: There were 11 (12.7%) males and 75 (87.2%) females with a mean age of 42.8 ± 14.6 years. Seventy-seven patients had undergone total thyroidectomy and in 67 (77.9%) some type of LN resection. In 76 (88.3%), 131I was administered after the initial surgery. We localized suspicious lymph nodes by US in all patients, and metastases were documented before surgery by FNA in 63. Seven (8.13%) patients underwent central LND, 63 (73.2%) lateral LND and 16 (18.6%) both, central and lateral LND. Major complications occurred in 6 patients (6.9%). Sixty-two (72.0%) patients received 131I after surgery. A second surgical re-exploration was performed in 30 (34.8%) patients, and 7 patients required 3 or more additional LND. In a mean follow-up of 59.4 ± 39 months, 51 (59.3%) patients are clinically, radiologically and biochemically free of disease. CONCLUSIONS: In this series, compartment-oriented lymph node resection of recurrent papillary thyroid carcinoma leads to a final clinical and biochemical disease-free status of 59.3% with 6.9% of major complications.

Substernal Goiter: Correlation between Grade and Surgical Approach.

Substernal goiter is defined as a thyroid growth beyond the thoracic inlet. Using the cross-section imaging CT system, it can be classified into three grades. The aim of the study was to validate the surgical approach and the occurrence of postoperative complications with substernal goiter extension in our patient population. From a total of 1145 patients who underwent thyroid surgery at our institution in a 15-year period, 60 patients with substernal goiter were included. Clinical features and demographics, degree of extension, surgical details, and complications were analyzed. Mean ± SD age of the patients was 58 ± 14.7 years and 88 per cent were females. According to the cross-section imaging CT system 61.7 per cent were grade I, 23.3 per cent grade II, and 15 per cent grade III. Total thyroidectomy was performed in 78.3 per cent of the patients, subtotal thyroidectomy in 18.3 per cent, and lobectomy in 3.3 per cent. The cervical approach was sufficient to perform 96.7 per cent of the thyroidectomies, requiring partial sternotomy in only two patients with grade III substernal goiter. Patients with grade III substernal goiter had a higher risk for postoperative dysphonia (OR = 14.29, IC95% 1.14-178.9, P = 0.03), which occurred in three patients (two transient and one permanent). Transitory hypoparathyroidism was present in 20 patients (33.3%) and did not correlate with goiter extension. Most substernal goiters can be resected through a cervical approach, with relatively low morbidity. Postoperative dysphonia was directly related to the extension of the goiter. Few cases with grade III goiters require a partial sternotomy.

[Immunoglobulin G4-associated to multiorganic lymphoproliferative disease]. / Enfermedad linfoproliferativa multiorgánica asociada a inmunoglobulina G4.

We report a case of a woman with lymphoproliferative multiorganic immunoglobulin G4 (IgG4) related disease with extensive involvement showing dacryoadenitis, sialoadenitis, parotiditis, pancreatitis, pneumonitis, lymphadenopathy and immune thrombocytopenic purpura. Serum elevation of acute phase reactant, polyclonal hypergammaglobulinemia, positivity for antinuclear antibodies and rheumatoid factor was found. Hystologically plasma cell infiltration was demonstrated on glandular and lymphatic tissue and immunochemistry was positive for IgG4 in > 30%. Immunosuppressive treatment with steroids and azathioprine was given with an excellent clinical response, the marked radiologic evidence of improvement and the decrease in inflammatory makers that conducted to symptom remission are shown in the text.
