Project description:BackgroundPrimary pericardial mesothelioma (PPM) is a rare malignancy with a high prevalence of mortality. The diagnosis is usually challenging using a variety of imaging modalities and invasive procedures and is generally performed at the later stages of the disease or in autopsy. This case study points to an unconventional presentation of PPM and the challenges in diagnosing this rare mortal malignancy.Case presentationThis study presents a 44-year-old woman with no remarkable medical history with an initial diagnosis of effusive constrictive pericarditis at first hospitalization. Imaging evaluations, including transthoracic echocardiography and chest computed tomography scan, demonstrated visible thickened pericardium, pericardial effusion, and mass-like lesions in pericardium and mediastinum. The definite diagnosis of primary pericardial mesothelioma was established after pericardiectomy and histopathology examinations. Chemotherapy with pemetrexed and carboplatin was administrated to the patient, and she has been through four cycles of chemotherapy with no complications to date.ConclusionConstrictive pericarditis is an uncommon presentation of PPM. Due to the high mortality rate and late presentation, difficulties and uncertainties in diagnosis, being aware of this rare malignant entity in different cardiac manifestations, particularly when there is no clear explanation or response to treatment in such conditions, is highly important.

Project description:IntroductionPrimary malignant pericardial mesothelioma is a very rare pericardial tumor of unknown etiology.Case presentationA 61-year-old Caucasian woman was admitted to our hospital complaining of exertional dyspnea due to a large pericardial effusion. Intrapericardial fluid volume declined after repeated pericardiocentesis, but the patient progressively developed a hemodynamically relevant pericardial constriction. Pericardiectomy revealed a pericardial mesothelioma. Subsequently, four cycles of chemotherapy (dosage according to recently published trials) were administered. The patient remained asymptomatic, and there was no recurrence of the tumor after three years.ConclusionPericardial mesothelioma should be considered and managed appropriately in non-responders to pericardiocentesis, and in patients who develop constrictive pericarditis late in their clinical course.

Project description:BackgroundPrimary pericardial mesothelioma is a rare primary cardiac malignancy, with three main histopathological types, sarcomatoid histotype being the rarest. The imaging features were atypical due to concomitant extensive calcification, which resulted in aggravated differential diagnosis.Case summaryA 45-year-old man presented to our hospital with non-specific clinical symptoms. According to clinical history, a mediastinal tumour had been suspected with a previous unsuccessful attempt of transthoracic computed tomography-guided biopsy at an overseas hospital with limited data of performed imaging procedures. Multimodality imaging at our centre revealed extensively calcified solid masses in the pericardium, invading the left atrium. As the imaging features suggested an atypical primary pericardial malignancy, a diagnostic thoracoscopy was performed. Histopathological analysis of specimen revealed sarcomatoid type of pericardial mesothelioma with areas of necrosis and foci of osteogenic differentiation. Despite planned treatment, 2 weeks after histological diagnosis, the patient passed away due to perforated peptic ulcer-related sepsis.DiscussionThe presence of extensive calcification in the lesion resulted in a challenging imaging workup and diagnosis. Initial differential diagnosis included primary or metastatic calcification-prone tumour, secondary calcification due to haemorrhage after previous interventional procedure and other pathologies, such as tuberculous pericarditis, calcified amorphous tumour, among others. Calcification may be part of the histological tumour characteristics; however, proper history taking is crucial as concomitant diseases, previous treatment, and interventional procedures may alter the imaging pattern.

Project description:The symptoms and signs of constrictive pericarditis (CP) are often elusive at onset, with a long symptom-free period that may take weeks to decades to develop after an episode of CP or pericardial injury, leading to a misdiagnosis. In this case, a 58-year-old man complained of lower extremity fatigue, intermittent chest tightness, and shortness of breath. He was first misdiagnosed as neuropathy, later unsuccessfully treated as ischaemic heart disease though severe stenosis of the diagonal branch of left anterior descending artery was confirmed by computer tomography angiography. He was finally diagnosed as CP after carefully reading the initial computed tomography. The gross pathology of heart in situ originally observed at the time of pericardectomy indicated fibrinous pericarditis, massive haemorrhagic pericardial effusion (300 mL), and thickened pericardium (maximum thickness more than 6 mm). Following pericardial tissue biopsy, the histopathology showed chronic fibrinous pericarditis, without a clear aetiology. His symptoms gradually disappeared after surgical pericardectomy. At the 1-year follow-up visit, the patient complained of no discomfort. Constrictive pericarditis is one of the serious diseases commonly misdiagnosed. Computed tomography and echocardiography show the important diagnostic role in patients with CP, and surgical pericardectomy shows the potential in treating this disease, in some of which the mechanism underlying large haemorrhagic pericardial effusion remains unclear.

Project description:We present the case of a 55-year-old female marathon runner who presented with progressive exercise intolerance and was diagnosed with effusive-constrictive pericarditis. Stereotypical findings of this challenging diagnosis are shown by transthoracic echocardiographic and right heart catheterization. We treated the patient with a parietal pericardiectomy and pericardial waffle procedure to relieve a thick and constrictive epicardium.

Project description:Constrictive pericarditis is a rare cause of right-sided heart failure secondary to a stiff, non-compliant pericardium. Clinical presentation can vary considerably and requires a high suspicion for diagnosis. A 31-year-old male presented to the emergency department with complaints of abdominal distension. An abdominal ultrasound revealed large volume ascites; thus, it was initially suspected he had underlying cirrhosis. However, an echocardiogram revealed a diagnosis of constrictive pericarditis. It's important for clinicians to consider constrictive pericarditis in a patient presenting with unexplained right-sided heart failure.

Project description:BackgroundPrimary pericardial mesothelioma is an extremely rare disease. Prognosis is poor, with little effects of chemo- or radio-therapy. The majority of cases is diagnosed at autopsy.Case summaryA 22-year-old man, who presented with recurrent pericarditis and large pericardial effusion 2 months after a second BNT162b2 COVID-19 vaccine, underwent pericardiocentesis and pericardial window. Pathology specimen of pericardium revealed benign mesothelial inflammation, consistent with acute pericarditis. Four months later, he presented with a large pericardial mass manifesting in heart failure and underwent urgent pericardiectomy. A new pathology specimen immunostaining and fluorescence in situ hybridization analysis revealed pericardial mesothelioma. Despite intensive care, the patient died 3 weeks later.DiscussionPrimary pericardial mesothelial should be considered in the differential diagnosis of refractory recurrent pericarditis, even with prior biopsy-proven pericarditis or when a putative trigger (COVID-19 mRNA prior vaccination) is suspected, as was the case in this patient. Tumour diagnosis and identification consist of multimodal imaging and laboratory tests. A multidisciplinary, individualized care approach should be performed.
