All that clots is not blood: Bone cement implantation syndrome presenting as an intracardiac mass and pulmonary embolism

Bone cement implantation syndrome (BCIS) is a rare and potentially fatal perioperative complication of cemented orthopaedics surgery. A CT-pulmonary angiogram and echocardiogram images were acquired from an 88-year-old patient who had a perioperative collapse while undergoing a revision operation for a peri-implant fracture of the right femoral neck. Findings were suggestive of an intracardiac clot connected to a saddle pulmonary artery embolus. Patient also developed disseminated intravascular coagulation. Overall findings were suggestive of bone cement implantation syndrome.

Erdheim-Chester disease presenting as a intracardiac mass and pericardial effusion confirmed by biopsy: a case report

Background Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis that can affect the bones, heart, lungs, brain, and other organs. Cardiovascular involvement is common in ECD and is associated with a poor prognosis. Here, we report a case of ECD presenting as a intracardiac mass and pericardial effusion confirmed by biopsy with sternotomy. Case summary A 54-year-old man was admitted because of dyspnoea. He was previously diagnosed with bilateral hydronephrosis and retroperitoneal fibrosis. Echocardiography revealed a large amount of pericardial effusion and echogenic mass on the right atrial (RA) side and atrioventricular (AV) groove. Cardiac magnetic resonance imaging and positron emission tomography-computed tomography (CT) revealed infiltrative mass-like lesions in the RA and AV groove. Pericardial window formation and pericardial biopsy were performed, and the pathologic results showed only pericardial fibrosis with no specific findings. Bone scan revealed increased uptake in the long bones. Considering the high probability of ECD based on the patient’s manifestations and the imaging findings, we performed a cardiac biopsy with median sternotomy despite initial insufficient pathologic results in the pericardial biopsy. The surgical findings included multiple irregular and firm masses on the cardiac wall and large vessels; after obtaining a large amount of suspicious mass, ECD accompanied with CD68 (+) and BRAF V600E mutation was confirmed. Discussion ECD can be associated with various forms of cardiovascular involvement. Considering the multi-systemic manifestations and difficulty in identifying this rare disease, a comprehensive and meticulous diagnostic work-up is crucial.

Lipoma across the Wall of the Right Atrium

A 44‑year‑old male patient was referred to our department with unremarkable physical examination and laboratory data due to a mass which was incidentally found in the right atrial during a routine examination.Transthoracic and transesophageal echocardiography revealed a 46×30 mm, well-delimited, non-mobile mass in the superior portion of the right atrium. Besides the intracardiac mass, another low density was detected in adjacent pericardial cavity at cardiac computed tomography ;he extracardiac mass appeared to be caused by invasive growth from the intracardiac mass.An operation was performed through right anterolateral minithoracotomy with the patient under hypothermic cardiopulmonary bypass. During operation, it was found that the surface of the right atrium was covered by an adipose mass (30×40 mm; Fig. 2A). Intracardiac mass also showed yellow adipose tissue (40×50 mm; Fig. 2B). Both parts of the mass infiltrated the myocardium. The mass was resected completely; and right atrium was reconstructed by using bovine pericardium pad. After the operation, the pathology confirmed the both intracardiac and extracardiac tissues as lipoma; transthoracic echocardiogram showed the atrial mass was removed completely and the left ventricular ejection fraction was normal . The patient’s postoperative course was uneventful and he was discharged home after 7 days.

Neonatal Tuberous Sclerosis: is skin really the window?

We report a case of a neonate who was diagnosed to have intracardiac mass as a fetus and presented with white linear papules that was diagnosed to be Linear Verrucous Epidermal Nevus. Apart from the intracardiac mass, most likely rhabdomyoma, MRI Brain also showed presence of tubers and the Next Generation Sequence Analysis confirmed the diagnosis of Neonatal Tuberous Sclerosis. The neonate remained asymptomatic and was discharged home and remains under close follow up without any symptoms. It is thus suggested that Linear Verrucous Epidermal Nevus, a cutaneous manifestation not described with Tuberous Sclerosis could be considered under the ever-expanding cutaneous signs of Tuberous Sclerosis and should alert the physician toward its possibility.
