Raríssimo caso de pericardite constritiva: sangramento pericárdico pós-traumático por causa inusitada / Very rare case of constrictive pericarditis: post-traumatic pericardial bleeding due to an unusual cause

APRESENTAÇÃO DO CASO: Paciente do sexo masculino, 69 anos, fumante, sem outras comorbidades, agricultor, consulta por dispnéia. Ao exame físico na admissão apresenta sinais de insuficiência cardíaca direita. Foi realizado ecocardiograma com evidência de massa adjacente ao ventrículo direito (VD), causando compressão com diminuição a distensibilidade do VD, com áreas de intensa calcificação pericárdica de distribuição desigual e padrão hemodinâmico de constrição. Nega antecedentes de tuberculose, radioterapia de tórax ou cirurgia cardíaca prévia. Realizada TC de tórax com contraste, evidenciando calcificações pericárdicas, com imagem de "pseudotumor" adjacente a VD de contorno irregular, calcificação intensa e conteúdo heterogêneo. O paciente foi submetido a pericardectomia e ressecção do tumor, com achado de intensa calcificação e coágulos remanescentes em seu interior. Interrogado especificamente sobre antecedente de trauma torácico, ao que o paciente respondeu ter sofrido uma pancada por cabeça de bovino, 10 anos antes do início dos sintomas. Descartou-se contato com Mycobacterium tuberculosis, tireoidopatias e neoplasias. Em ausência de outra explicação que justificasse os achados, foi assumida como etiologia pericardite constritiva secundária a hemopericárdico por contusão cardíaca. DISCUSSÃO: As causas mais comuns de pericardite constritiva incluem tuberculose, colagenoses, uremia, febre reumática, radioterapia, neoplasias. Existem pouquíssimos relatos na literatura relacionando pericardite constritiva a trauma torácico fechado, a maioria das associações são com o trauma da pericardiectomia durante uma cirurgia cardíaca. Chama a atenção a intensa calcificação pericárdica com efeito de massa compressiva adjacente ao VD e a localização heterogênea das calcificações nas paredes de VE, podendo corresponder com a distribuição pós-traumática do sangramento. Apesar de ser relatado na literatura que a tuberculose está entre as causas que mais apresentam calcificação visível ao exame radiológico, não há evidências que ligam a alteração a uma etiologia específica. COMENTÁRIOS FINAIS: Pelo perfil da população que atendemos no SUS, devemos abrir o espectro de possibilidades para não nos surpreendermos com motivos inusitados de consulta na população. Não há casos publicados de pericardite pós-traumática, secundária a hemopericárdio pós pancada de bovino. Com a grande quantidade de trabalhadores rurais no Brasil, sua incidência poderia estar sendo subestimada.

Evaluation of Pericardial Effusions in Alopecia Patients on Low-Dose Oral Minoxidil Therapy.

BACKGROUND: Minoxidil is an anti-hypertensive vasodilator increasingly used off-label for the treatment of alopecia. It is associated with an increased risk of pericardial effusions, with recent reports even in patients on low-dose oral minoxidil (LDOM) therapy. OBJECTIVE: To evaluate whether LDOM is associated with increased prevalence of pericardial effusions in patients with alopecia. METHODS: In this cross-sectional study, point-of-care ultrasound was used to screen alopecia patients at dermatology appointments. Scans were evaluated by two independent cardiologists for the presence and size of effusions. The prevalence of effusions was compared between patients on LDOM therapy and patients not on minoxidil therapy. RESULTS: A total of 100 patients were evaluated for pericardial effusion: 51 LDOM patients and 49 control patients. The two groups were similar in terms of age (53.7 vs 54.1; P=0.91), sex (86% vs 73% female; P=0.14), and race. Small pericardial effusions (<1 cm) were identified in 5.8% of LDOM patients and 6% of control patients (P=1), none of which were symptomatic. LIMITATIONS: This is a small, cross-sectional study with limitations on speculation of causality in confirmed cases. CONCLUSION: We did not find evidence of increased prevalence of pericardial effusions in a small group of alopecia patients on LDOM. J Drugs Dermatol. 2024;23(9):725-728. doi:10.36849/JDD.8029.

[Application of cell blocks to assist in precise cytological diagnosis of serous effusion].

Objective: To investigate the importance of cell block and immunohistochemistry in the accurate diagnosis of serous effusion. Methods: A retrospective study was conducted on 3 124 cases of serous effusion from the Department of Pathology, Beijing Hospital from 2018 to 2022, include 2 213 cases of pleural effusion, 768 cases of peritoneal effusion, 143 cases of pericardial effusion. There were 1 699 males (54.4%) and 1 425 females (45.6%), average age 69 years old. Of which 1 292 cases were prepared with cell blocks and examined with immunohistochemical stain. Results: The percentage of malignant diagnosis increased from 64.9% (839/1 292) to 84.0% (1 086/1 292) after cell block preparation, and 1 086 cases were accurately diagnosed with histological type and/or origin of primary tumor. The undetermined diagnosis of suspected malignancy decreased from 13.3% (172/1 292) to 0.1% (1/1 292) and that of atypical hyperplasia from 18.8% (243/1 292) to 0.4% (5/1 292). The negative result for malignancy rate increased from 3.0% (38/1 292) to 15.5% (200/1 292). The differences highlighted above were statistically significant (Pearson's chi-squared test=12.739, P<0.01). Conclusion: Application of immunohistochemistry based on cell block can significantly improve malignant diagnosis in serous effusion, identify tumor origin and histological type as well as decrease the uncertain diagnosis.

A Rare Case of Effusive Pericarditis: Overlap Syndrome.

Systemic autoimmune disease contributes up to ~22% of cases of pericarditis with known etiology. Systemic lupus erythematosus (SLE) is a multisystem disease with a variety of clinical presentations and manifestations. Since the underlying mechanism for pericardial involvement differs with each systemic disease, this leads to poor understanding of its management. However, it is rare for acute pericarditis to be the leading symptom at the time of diagnosis of SLE, occurring in up to 1% of patients. This is a case report of a 21-year-old female who presented with breathlessness and pedal edema, who was previously misdiagnosed with tubercular pericarditis and was started on antitubercular treatment (ATT). Now she is diagnosed with autoimmune pericarditis with SLEoverlap syndrome. Pericarditis, being the most common cardiac manifestation of SLE, has an incidence ranging between 11 and 54%. Knowledge of such association is necessary to avoid misdiagnosis.

Diagnostic value of combined CT lymphangiography and 99Tcm-DX lymphoscintigraphy in primary chylopericardium.

OBJECTIVE: To investigate the diagnostic value of combined 99Tcm-DX lymphoscintigraphy and CT lymphangiography (CTL) in primary chylopericardium. METHODS: Fifty-five patients diagnosed with primary chylopericardium clinically were retrospectively analyzed. 99Tcm-DX lymphoscintigraphy and CTL were performed in all patients. Primary chylopericardium was classified into three types, according to the 99Tcm-DX lymphoscintigraphy results. The evaluation indexes of CTL include: (1) abnormal contrast distribution in the neck, (2) abnormal contrast distribution in the chest, (3) dilated thoracic duct was defined as when the widest diameter of thoracic duct was > 3 mm, (4) abnormal contrast distribution in abdominal. CTL characteristics were analyzed between different groups, and P < 0.05 was considered a statistically significant difference. RESULTS: Primary chylopericardium showed 12 patients with type I, 14 patients with type II, and 22 patients with type III. The incidence of abnormal contrast distribution in the posterior mediastinum was greater in type I than type III (P = 0.003). The incidence of abnormal contrast distribution in the pericardial and aortopulmonary windows, type I was greater than type III (P = 0.008). And the incidence of abnormal distribution of contrast agent in the bilateral cervical or subclavian region was greater in type II than type III (P = 0.002). CONCLUSION: The combined application of the 99Tcm-DX lymphoscintigraphy and CTL is of great value for the localized and qualitative diagnosis of primary chylopericardium and explore the pathogenesis of lesions.

Constrictive pericarditis in a patient with fiberglass lung disease: a case report.

BACKGROUND: Fiberglass has a larger aerodynamic diameter and is less likely to be inhaled into the lungs. Further, it will be cleared even if it is mechanically broken into smaller pieces and inhaled into the lungs. Fiberglass lung disease has been well documented if long term exposure but was thought reversible and would not cause severe diseases. The diagnosis of fiberglass lung disease depends on exposure history and histopathological findings. However, the exact occupational exposure history is often difficult to identify because mixed substance exposure often occurs and fiberglass disease is not as well-known as asbestosis. CASE PRESENTATION: A 66-year-old man had unexplained transudative pericardial effusion requiring pleural pericardial window operation twice at another medical center where asbestosis was told because of his self-reported long-term asbestosis exposure and the histopathological finding of a ferruginous body in his lung. Constrictive pericarditis developed two years later and resulted in congestive heart failure. Radical pericardiectomy combined with lung biopsy was performed following chest computed tomography imaging and the transudative nature of pericardial effusion not compatible with asbestosis. However, the histopathologic findings of his lung and pericardium at our hospital only showed chronic fibrosis without any asbestosis body. The patient's lung was found to be extremely fragile during a lung biopsy; histopathologic specimens were reviewed, and various fragments of fiberglass were found in the lung and pericardium. The patient's occupational exposure was carefully reevaluated, and he restated that he was only exposed to asbestosis for 1-2 years but was heavily exposed to fiberglass for more than 40 years. This misleading exposure history was mainly because he was only familiar with the dangers of asbestos. Since most fiberglass lung diseases are reversible and the symptoms of heart failure resolve soon after surgery, only observation was needed. Ten months after radical pericardiectomy, his symptoms, pleural effusion, and impaired pulmonary function eventually resolved. CONCLUSION: Fiberglass could cause inflammation of the pericardium, resulting in pericardial effusion and constrictive pericarditis, which could be severe and require radical pericardiectomy. Exact exposure history and histopathological examinations are the key to diagnosis.

Central lung adenocarcinoma in a young male mimicking pneumonia with nonrecurrent polyserous effusions of negative cytology: A case report.

INTRODUCTION AND IMPORTANCE: Lung adenocarcinoma may resemble the clinical presentation of an infectious or inflammatory lung disease. The coexistence of lung cancer, and polyserous effusions is uncommon, which may cause a diagnostic challenge. However, any polyserous effusions at a young age must always be suspicious for malignancy. CASE PRESENTATION: We report a case of 38-year-old male patient with polyserous effusions and pneumonia who was treated accordingly and showed clinical improvement with a significant reduction of pericardial and pleural effusions. Subsequent testing and a biopsy resulted in the histopathological diagnosis of an adenocarcinoma of the lung. CLINICAL DISCUSSION: Nonrecurrent polyserous effusions in lung adenocarcinoma are uncommon, and negative cytology results may not exclude malignancy due to the moderate sensitivity of pleural and pericardial fluid cytology. Clinicians should remain vigilant for false-negative results, especially in younger patients. Malignancy should not be ruled out because pleural and pericardial fluid cytology have a sensitivity of 60% and 92%, respectively. CONCLUSION: Our case highlights the diagnostic challenges posed by atypical presentations of lung adenocarcinoma and emphasizes the importance of considering malignancy in the differential diagnosis of polyserous effusions, even when initial cytology results are negative. Clarifying the rationale for this study enhances its relevance and impact.

Cardiac tamponade in people living with HIV: a systematic review of case reports and case series.

BACKGROUND: Cardiac tamponade is a life-threatening condition requiring prompt diagnosis and therapeutic intervention. Diagnosis and management of cardiac tamponade in patients with human immunodeficiency virus (HIV) infection pose a major challenge for clinicians. This study aimed to investigate clinical characteristics, paraclinical findings, therapeutic options, patient outcomes, and etiologies of cardiac tamponade in people living with HIV. METHODS: Pubmed, Embase, Scopus, and Web of Science databases were systematically searched for case reports or case series reporting HIV-infected patients with cardiac tamponade up to February 29, 2024. Baseline characteristics, clinical manifestations, paraclinical findings, therapeutic options, patient outcomes, and etiologies of cardiac tamponade were independently extracted by two reviewers. RESULTS: A total of 37 articles reporting 40 HIV-positive patients with cardiac tamponade were included. These patients mainly experienced dyspnea, fever, chest pain, and cough. They were mostly presented with abnormal vital signs, such as tachypnea, tachycardia, fever, and hypotension. Physical examination predominantly revealed elevated Jugular venous pressure (JVP), muffled heart sounds, and palsus paradoxus. Echocardiography mostly indicated pericardial effusion, right ventricular collapse, and right atrial collapse. Most patients underwent pericardiocentesis, while others underwent thoracotomy, pericardiotomy, and pericardiostomy. Furthermore, infections and malignancies were the most common etiologies of cardiac tamponade in HIV-positive patients, respectively. Eventually, 80.55% of the patients survived, while the rest expired. CONCLUSION: Infections and malignancies are the most common causes of cardiac tamponade in HIV-positive patients. If these patients demonstrate clinical manifestations of cardiac tamponade, clinicians should conduct echocardiography to diagnose it promptly. They should also undergo pericardial fluid drainage and receive additional therapy, depending on the etiology, to reduce the mortality rate.

A case of t-cell lymphoblastic lymphoma characterized by pleural effusion combined with pericardial effusion.

This case underscores the pivotal role of early cytological examination of bodily fluids in the preliminary detection of lymphoma, a conclusion reinforced by subsequent pathological findings and refined through immunohistochemical characterization. A morphological analysis of pleural effusion cells was conducted in a 25-year-old male presenting initially with concurrent pleural and pericardial effusions. Initial morphological assessment of effusion specimens indicated the likelihood of a lymphoproliferative disorder. Subsequent detailed pathological and immunohistochemical investigations confirmed this suspicion, culminating in a definitive diagnosis of T-cell lymphoblastic lymphoma (T-LBL). The case emphasizes the necessity of employing a comprehensive and synergistic diagnostic approach, facilitating prompt and accurate diagnosis and subtyping of lymphoma.

Malignant Pericardial Effusion from Cervical Squamous Cell Carcinoma: A Case Study.

BACKGROUND Cervical cancer ranks fourth globally among women's cancers. Squamous cell carcinoma constitutes 70% of cervical cancer cases, often metastasizing to lungs and paraaortic nodes. Uncommon sites include the brain, skin, spleen, and muscle, while pericardial fluid metastasis is highly rare. We report a case of squamous cell carcinoma of the uterine cervix that was metastatic to the pericardium and was detected on cytologic evaluation of pericardial fluid. CASE REPORT A 42-year-old woman who was previously treated for stage III squamous cell carcinoma of the cervix presented with symptoms of cough, fever, and shortness of breath for 8 days, and chest pain for 3 days. Clinical workup revealed pericardial effusion, with spread to the lungs and mediastinal and hilar lymph nodes. Cytological analysis of the fluid showed malignant cells, consistent with metastatic squamous cell carcinoma. Immunohistochemistry demonstrated cells positive for p63 and p40, while negative for GATA-3, D2-40, calretinin, and WT1. These findings in conjunction with patient's known history of cervical squamous cell carcinoma was consistent with a cytologic diagnosis of metastatic squamous cell carcinoma to pericardial fluid. CONCLUSIONS History and clinical correlation plays a vital role in determining the primary site causing malignant pericardial effusions. While the occurrence of cervical cancer metastasizing to the pericardium is uncommon, it should be considered, particularly in cases involving high-grade, invasive tumors, recurrences, or distant metastases. This possibility should be included in the list of potential diagnoses when encountering pericardial effusions with squamous cells in female patients.

Ruptured pulmonary artery aneurysm with prior dissection and persistent ductus arteriosus: Autopsy case report.

Cardiac tamponade from ruptured intrathoracic organs can lead to sudden cardiac death. In rare circumstances, the pulmonary artery can be the source of hemopericardium. We describe a case of a 62-year-old woman with no significant past medical history, who presented with sudden unexpected death. A forensic autopsy revealed 500 ml of hemopericardium. Further dissection demonstrated a saccular aneurysm in the pulmonary artery trunk, along with the evidence of prior dissection, i.e., neointimal layer. Persistent ductus arteriosus (PDA) was also present. Pulmonary artery aneurysms (PAA) are rare and often associated with congenital heart disease (CHD). PDA is the most common CHD related to PAA. Secondary pulmonary hypertension makes the pulmonary artery vulnerable to medial degeneration and increases the risk of dissection and rupture. Careful inspection of the great vessels and congenital anomalies are essential in the forensic autopsies for sudden death investigation.

Pericardial Effusion as a Complication of Severe Primary Hypothyroidism.

Large pericardial effusions with associated cardiac tamponade are a rare manifestation of hypothyroidism. We present the case of a 63-year-old female with chronic heart failure and newly diagnosed hypothyroidism, who presented to her primary care physician complaining of progressively worsening dyspnea. Chest radiography showed cardiomegaly and transthoracic echocardiography (TTE) revealed a large pericardial effusion with tamponade physiology. An emergent pericardial window was performed, resulting in an improvement in left ventricular systolic function. Pericardial tissue biopsy was normal. Thyroid function tests were consistent with severe primary hypothyroidism. After inpatient treatment with intravenous levothyroxine and interval resolution of symptoms without recurrence of effusion, the patient was discharged home on oral levothyroxine therapy. Close follow up with surveillance echocardiography was planned. While metabolic disorders are seldom thought of as an etiology, it is imperative for clinicians to recognize hypothyroidism as a cause of the pericardial effusion. It is one of the few reversible causes and delay in treatment can result in fatal sequelae.

Apixaban-Induced Hemopericardium in a Post-TAVR Patient: A Case Report Highlighting Diagnostic and Management Challenges.

BACKGROUND Despite having many benefits, frequently-used medications may still have potential risks and can cause harm. Hemopericardium is a lethal pathology with a high risk of mortality and a lower differential diagnosis consideration. When adding both mentioned elements, their consideration as a differential diagnosis would require a higher threshold. This report presents a 66-year-old man with atrial fibrillation, heart failure, and aortic stenosis status post transcatheter aortic valve replacement (TAVR) 1 year ago with hemopericardium while treated with apixaban. CASE REPORT We present the case of a 66-year-old man with multiple medical conditions, including atrial fibrillation, heart failure, and aortic stenosis post-transcatheter aortic valve replacement 1 year before admission, who presented with 2 weeks of dyspnea and lower-limb swelling. Initial assessments revealed atrial fibrillation, elevated brain natriuretic peptide, and a chest X-ray indicating possible left pleural effusion and cardiomegaly. On day 4, an echocardiogram identified a large hemopericardium and tamponade, prompting urgent surgery. A pericardial window was performed, draining 1700 cc of bloody fluid. The postoperative improvement included normalized hemodynamics and echocardiographic findings. Pathology confirmed hemopericardium. The follow-up echocardiogram showed improved cardiac function, and the patient was transferred to the general medical floor. CONCLUSIONS This case sheds light on the uncommon but critical complications associated with direct oral anticoagulant therapy. With only a handful of reported cases, the rarity of this condition underscores the need for heightened awareness among clinicians. The patient's intricate medical history accentuates the challenges in managing anticoagulation in individuals with multiple comorbidities.

Neonatal lupus erythematosus presenting with effusions: A 13-year retrospective study.

OBJECTIVES: Neonatal systemic lupus erythematosus (NLE) is an acquired autoimmune disease. The presence of effusions, such as pleural effusion and pericardial effusion, is rare. The present study helped investigate the clinical characteristics and progression of children with NLE combined with effusions. METHODS: Clinical data of patients diagnosed with NLE were retrospectively collected and analyzed from January 1, 2011, to December 31, 2023, at the Children's Hospital of Soochow University and Suzhou Municipal Hospital. Patients with NLE were divided into effusion and non-effusion groups based on the presence of effusion. Moreover, the clinical data of the newborns in both groups were compared and investigated. RESULTS: Eleven (11/45, 24.44%) NLE patients had effusions, such as pleural effusion, testicular hydrocele, peritoneal effusion, pericardial effusion, and hydrocephalus. Other organs involved in effusion patients were cutaneous, gastrointestinal, hematologic, cardiac, and neurological. Among the patients with effusion, five cases of SLE in pregnant mothers, two cases of Sjogren's syndrome, one case of photoallergic symptoms, and three of pregnant mothers with no history of antenatal autoimmune disease. Pregnant mother' autoimmune disease in remission prior to pregnancy, or stable low disease activity. Seven patients were positive for Anti-SSA, five of which were double positive for Anti-SSA and Anti-SSB. Compared with the non-effusion group, the effusion group patients had significantly higher lactate dehydrogenase, creatine kinase, and fibrinogen, significantly lower platelets, total protein, and albumin. These patients were likelier to have thrombocytopenia and coagulation abnormalities. Logistics regression analysis demonstrated that NLE patients with effusions are more likely to have decreased serum total protein levels. All NLE patients with effusion have self-resorption of the effusion. CONCLUSIONS: 24.44% of patients had effusions in our study. NLE patients with effusion are more likely to have hematologic involvement and a more inflammatory response. The effusion in NLE patients is usually self-resorption, severe cases can be treated with nonsteroidal anti-inflammatory drugs/steroids. Key Points • NLE patients combined with effusions and were self-limiting, with pleural effusion being the most common. • NLE patients combined with effusions have a more inflammatory response, significant abnormalities in the blood routine and biochemical-related indexes.

Pericardial tamponade after laparoscopic repair of a giant diaphragmatic hernia.

Laparoscopic intraperitoneal onlay mesh repair is favoured for diaphragmatic hernias due to better outcomes. However, fixation devices pose risks, including cardiac tamponade. A man underwent laparoscopic repair for a large diaphragmatic hernia. One week later, he presented with chest discomfort which was initially attributed to postoperative pain. Subsequently, patient represented with worsening of chest pain and tachycardia. CT requested to rule out pulmonary embolism revealed a large pericardial effusion. Urgent drainage via apical approach resolved tamponade. The case highlights the challenges in managing pericardial effusions post-laparoscopy in the presence of diaphragmatic mesh and stresses multidisciplinary collaboration. Literature review highlights risks associated with fixation devices. Suggestions include limiting their use near vital structures. Key learning point of this case report is to raise awareness of cardiac tamponade following diaphragmatic hernia repair. Limited evidence necessitates cautious use of fixation devices, emphasising patient safety.

Camptodactyly-arthropathy-coxa vara-pericarditis (CACP) syndrome.

Camptodactyly-arthropathy-coxa vara-pericarditis syndrome (CACP) is a rare autosomal recessive disease caused by mutation in proteoglycan 4 (PRG4) gene on chromosome 1q25-q31. We faced a dilemma and delay in diagnosis in two sisters. The elder sister had pericardial effusion with constrictive pericarditis, underwent pericardiectomy and received empirical treatment for suspected tuberculosis. After 2 years, she developed bilateral knee swelling with restriction of movement. At the same time, her younger sister also presented with bilateral knee swelling which aroused the suspicion of genetic disease. The whole-genome sequencing revealed homozygous PRG4 mutation suggestive of CACP syndrome.

[A complicated left atrial appendage closure : percutaneous management of LAA rupture]. / Ma fermeture d'auricule s'est compliquée : traitement percutané d'une rupture d'auricule gauche.

An 81-year-old patient was referred for left atrial appendage closure. Anatomical LAA analysis by CT scan showed an inverted chicken wing morphology. The procedure was performed through i an infero-anterior transseptal puncture and led to "sandwich" closure strategy using an AMPLATZER AMULET 25 mm device. Despite successful deployment of the occluder, a hemopericardium soon developed related to an iatrogenic LAA perforation/partial rupture and leading to major hemodynamic instability. After pericardocentesis, it was decided to inject activated thrombin into the pericardial sac to achieve in situ hemostasis. This strategy enabled coagulation of the hemopericardium and cessation of active bleeding, without recourse to surgical treatment.
