Project description:BackgroundLipomatous hypertrophy of the interatrial septum (LHIAS) is a common finding on transthoracic echocardiogram (TTE). Occasionally, the appearance of LHIAS is atypical and multimodality imaging is helpful to make the diagnosis. We present a case of atypical LHIAS to highlight the potential aetiologies for an interatrial septal mass and review features on multimodality imaging that help decrease uncertainty and establish a diagnosis.Case summaryA 64-year-old man with a history of hypertension, diabetes mellitus, and coronary artery disease with multiple percutaneous coronary interventions presented to the emergency room with chest pain. Transthoracic echocardiogram showed a homogenous echo-dense, intracardiac mass present within the interatrial septum. Computed tomography (CT) angiogram of the chest showed a homogenous mass similar in radiodensity to extracardiac and pericardial fat. Cardiac magnetic resonance (CMR) confirmed LHIAS by homogenous signal that was nulled on fat suppression images.DiscussionThis case highlights that while most LHIAS has the standard 'dumbbell' appearance on TTE, there are instances where it can appear more like an adherent mass prompting a wider differential. Unenhanced CT of the heart can be used to confirm LHIAS by the presence of low attenuation values for tissue. Alternatively, CMR can be used for tissue characterization and confirmation of LHIAS. Precontrast T2/T1-weighted CMR images with steady-state free precession show high signal intensity in the area of LHIAS and produce a black/hypointense boundary effect between fat and myocardium. A multimodality approach is crucial in arriving at the appropriate diagnosis using the tissue characterization capabilities of CT and CMR.

Project description:Lipomatous atrial septal hypertrophy (LASH) is a histological cardiac benign lesion finding with high prevalence in healthy population, usually detected during imaging procedures for other indications. Nevertheless, it could become clinically significant if it compromises venous return and diastolic left ventricular filling, up to becoming an anatomical substrate for atrial tachyarrhythmias. We present a case of LASH diagnosed in a 54-year-old female patient admitted to our emergency department after ground fall and collateral finding of positive blood cultures leading to transesophageal echocardiography. A giant mass involving the interatrial septum was observed, in the absence of primitive neoplasia evidence after performing a total-body computed tomography scan and abdominal echography. No signs or symptoms of pulmonary venous congestion were observed, and no relevant tachyarrhythmias were detected at continuous electrocardiogram monitoring during the hospitalization period.

Project description:A 55-year-old patient was found to have complete heart block during preoperative assessment. Cardiac magnetic resonance imaging revealed an interatrial mass suggestive of primary cardiac tumor. Extensive evaluation including intracardiac biopsy and finally open resection revealed lipomatous hypertrophy masquerading as tumor. (Level of Difficulty: Intermediate.).

Project description:Intracardiac bronchogenic cysts are extremely rare congenital anomalies that arise during foregut development when the embryologic heart tube and ventral foregut are in close proximity to one another. We report a case of an interatrial septal bronchogenic cyst found on non-contrast enhanced computed tomography (CT) in a 66-year-old female who presented to the emergency department with chest pain. Further cardiac investigations, including contrast-enhanced CT angiogram of the heart, transthoracic echocardiogram, and transesophageal echocardiogram, revealed a cystic mass in the lipomatous interatrial septum. The patient was subsequently diagnosed with a bronchogenic cyst of the interatrial septum. No surgical intervention was pursued, as the mass remained stable, and the cardiothoracic surgeon did not recommend excision. This case highlights a rare case of a symptomatic bronchogenic cyst arising in the interatrial septum diagnosed by imaging modalities. Bronchogenic cysts should be included in the differential diagnosis of intracardiac tumors.

Project description:Asymmetrical left ventricular hypertrophy secondary to interventricular septum hypertrophy is usually considered a typical phenotype of hypertrophic cardiomyopathy. In rare cases other conditions such as tumors or lipomatous hypertrophy of the interventricular septum may have a similar presentation. We present a case of a male patient who presented for routine cardiology work up and was diagnosed of having ventricular septal hypertrophy secondary to localized lipomatous hypertrophy.

Project description:We report a case of a well-defined lesion in an asymptomatic patient with lipomatous ganglioneuroma (LG) located close to the left thoracic spine. Its intensity was heterogeneous with adipocytes. The lesion extended into the spinal canal through the enlarged left intervertebral without bony erosion. The imaging, clinical, and pathological features of the tumor are analyzed. Contrast-enhanced magnetic resonance imaging (MRI) revealed that the lesion was moderate enhanced. 18-F-fluoro-2-deoxyglucose-positron emission tomography/computed tomography (18FDG-PET/CT) demonstrated high 18-F-fluoro-2-deoxyglucose (18FDG) uptake of the tumor lesion. The finial preoperative diagnosis from our radiologists was that the tumor may be a liposarcoma or neurogenic tumor, but pathology showed that this was incorrect. Some related literatures were reviewed for reference to summarize imaging characteristics of this disease and to assist radiologists in making more accurate diagnoses. All of the lesions had adipocytes in reviewed literature, and the fat-suppressed images showed that there was some low signal intensity within the lesions, some lesions had widened neural foramina and extended into the spinal canal, and some lesion had calcifications. LG is an extremely rare variant of ganglioneuroma. Using the correct measurement of the CT value, applying MRI for fat-suppressed images, using in phase, out phase and contrast-enhanced sequences, using FDG-PET/CT, mastering LG imaging diagnostics characteristics, and combining all of this with clinical, morphological characteristics and pathology results can help clinical workers decrease the misdiagnosis rate of LG.

Project description:Bullous pemphigoid (BP) is a rare, life-threatening autoimmune blistering disease with pruritus and tension blisters/bullous as the main clinical manifestations. Glucocorticosteroids are the main therapeutic agents for it, but their efficacy is poor in some patients. Tofacitinib, a small molecule agent that inhibits JAK1/3, has shown incredible efficacy in a wide range of autoimmune diseases and maybe a new valuable treatment option for refractory BP. To report a case of refractory BP successfully treated with tofacitinib, then explore the underlying mechanism behind the treatment, and finally review similarities to other cases reported in the literature. Case report and literature review of published cases of successful BP treatment with JAK inhibitors. The case report describes a 73-year-old male with refractory BP that was successfully managed with the combination therapy of tofacitinib and low-dose glucocorticoids for 28 weeks. Immunohistochemistry and RNA sequencing were performed to analyze the underlying mechanism of tofacitinib therapy. A systematic literature search was conducted to identify other cases of treatment with JAK inhibitors. Throughout the 28-week treatment period, the patient experienced clinical, autoantibody and histologic resolution. Immunohistochemical analysis showed tofacitinib significantly decreased the pSTAT3 and pSTAT6 levels in the skin lesions of this patient. RNA sequencing and immunohistochemical testing of lesion samples from other BP patients identified activation of the JAK-STAT signaling pathway. Literature review revealed 17 previously reported cases of BP treated with four kinds of JAK inhibitors successfully, including tofacitinib (10), baricitinib (1), upadacitinib (3) and abrocitinib (3). Our findings support the potential of tofacitinib as a safe and effective treatment option for BP. Larger studies are underway to better understand this efficacy and safety.

Project description:Cardiac tumors are a rare phenomenon, and most cases are secondary to metastatic cancers rather than primary tumors. Renal cell carcinoma (RCC) is notorious for metastasis to cardiac tissue. Tumor thrombus migration to the renal vein and inferior vena cava happens in up to 10% of patients with RCC. Transitional cell carcinomas are another form of renal cancer, which may metastasize to the heart and are associated with widespread metastasis. Here, we report a patient with a past medical history of metastatic transitional cell cancer of renal pelvis under treatment with checkpoint inhibitor therapy presenting with shortness of breath. He had disseminated metastasis to bones, pleural space, lungs, and muscles. A large mass was found in the interatrial septum with invasion to the right and left atrium. The mass had a cystic component protruding into the left atrium. He passed away a few days after presentation.
