Diagnostic value of echocardiography in paracardiac cystic lesions: 43 cases from one single medical center

Surgical Management of Pericardial Cysts: A Single-Center Retrospective Study

Introduction Pericardial cysts (PCs) are infrequent, non-malignant, and congenital abnormalities. The identification and treatment of PCs remain a significant challenge, with limited research on surgical management. Methods We performed a retrospective study of patients with PCs who underwent surgical intervention at the First Affiliated Hospital of Xinjiang Medical University from February 2002 to December 2022. Results A total of 55 patients underwent surgery due to PCs during the study period. Thirty-one were females and 24 were males. The average age of the patients was 44.7 ± 12.9 (six to 63 years old). PCs were located in the right hemithorax in 50 (90.9%) patients and left hemithorax in five (9.1%) patients. Approach methods were video-assisted thoracoscopic surgery (VATS) in 43 (78.2%) cases; thoracotomy in 11 (20%) cases, and median sternotomy in one (1.8%) cases. The average postoperative hospitalization period was 5.6 days (two to 14 days). Three patients developed postoperative complications (two pleural effusion, one pneumonia), whereas no mortality was observed in any patient due to the operation. Forty-one patients (74.5%) were followed up for three months to eight years postoperatively, during which no recurrent cysts were detected. Conclusion In this single-center retrospective study, we demonstrated that pericardial cyst cure is an appropriate operation according to cyst characteristics. VATS has been shown to be highly effective and safe in patients with PCs, offering the advantage of reducing postoperative morbidity efficiently.

Prenatal ultrasound diagnosis of fetal giant pericardial cyst: A case report

RATIONALE

We describe 1 case of fetal giant pericardial cyst was diagnosed by fetal echocardiography in the second trimester, and the changes of the cyst were recorded by follow-up observation in the late trimester and after birth. We then review and discuss the knowledge about its diagnosis and treatment.

PATIENT CONCERNS

A 34-year-old pregnant woman was referred to our hospital because of a diagnosis of a fetal pericardial effusion at 22 5/7 weeks at another hospital.

DIAGNOSIS

Fetal echocardiography revealed an irregular anechoic area in the right side of the fetal right atrium and right ventricle that was closely related to but not communicated with the pericardiumis and suggested fetal pericardial cyst. Fetal cardiothoracic magnetic resonance imaging showed cystic FIESTA signal in the right lung region, with clear boundary, and a seemingly line-like low signal shadow within.

INTERVENTIONS

Since fetal pericardial cysts keep decreasing in size during maternal pregnancy, follow-up observation measures are taken.

OUTCOMES

Fetal pericardial cysts disappear on their own 4 months after delivery.

LESSONS

Asymptomatic pericardial cysts in the fetal period can be followed up and observed, and intervention is performed only when the cyst rapidly enlarges or ruptures and becomes infected in the fetal or neonatal period. Echocardiography can be used as a first-line detection method for their initial detection and follow-up.

Mediastinal thymic cysts: a narrative review

Background and Objective

Mediastinal thymic cysts are a relatively rare pathology. With the expansion of eligible individuals screened with cross-sectional imaging for lung cancer, it is likely that there will be an increase in the number of individuals presenting with these cysts. Understanding this rare pathology will become more important when this incidental pathology is encountered.

Methods

Search of PubMed was undertaken using keywords "mediastinal", "mediastinum", "thymic", "thymus", "cyst". Relevant literature was reviewed and selected for this comprehensive narrative review, including case reports, case series, and retrospective reviews.

Key Content and Findings

Thymic cysts in the mediastinum can be classified into two broad categories, congenital and inflammatory. Accurate diagnosis by imaging is challenging and the majority of patients are asymptomatic. Literature suggests that the majority of cysts are benign, however an unknown percentage may harbor neoplastic processes and over time can cause significant compressive symptoms. Definitive treatment and diagnosis is surgical, with overall excellent outcomes. The decision to pursue surgical treatment versus surveillance requires a shared decision making approach with patients.

Conclusions

Given the scarcity of available high quality evidence regarding the management of mediastinal thymic cysts, this review provides practitioners a broad knowledge base to guide patients to make informed decisions.

A Case of Esophageal Duplication Cyst Identified on Cardiac Point-of-Care Ultrasound

ABSTRACT

Esophageal duplication cysts are rare congenital anomalies that are often symptomatic because of compression of surrounding structures. They are commonly diagnosed during childhood, with affected patients often presenting with abdominal pain or chest pain. Point-of-care ultrasound can be used as part of the emergency department evaluation of pediatric chest pain. We present a case of a 6-year-old boy who presented to the emergency department with worsening abdominal and chest pain, where point-of-care cardiac ultrasound identified a cystic structure in the posterior mediastinum.
