ABSTRACT

Objective To observe the value of CT"cut-edge sign"for differentiating complex thymic cyst and thymic epithelial tumor(TET)with diameter less than 4 cm.Methods Data of 24 patients with complex thymic cyst(complex thymic cyst group)and 14 patients with TET(TET group)confirmed by surgical pathology who underwent plain and dual-phase enhanced chest CT scanning were retrospectively analyzed.CT"cut-edge sign"was evaluated by 2 physicians,and the inter-observer consistency was evaluated using intra-class correlation coefficient(ICC).The detection rate of CT"cut-edge sign"was compared between groups using logistic regression analysis.Receiver operating characteristic(ROC)curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficacy of CT"cut-edge sign"for differentiating complex thymic cyst and TET.Results The inter-observer consistency of CT"cut-edge sign"was good(ICC=0.94,95%CI[0.90,0.97]).The detection rate of CT"cut-edge sign"in complex thymic cyst group was 62.50%(15/24),higher than in TET group(2/14,14.29%)(P<0.01).The sensitivity,specificity,accuracy and AUC of CT"cut-edge sign"for differentiating complex thymic cyst and TET was 62.50%(15/24),85.71%(12/14),71.05%(27/38)and 0.74,respectively.Conclusion CT"cut-edge sign"was helpful for differentiating complex thymic cyst and TET with diameter less than 4 cm.

ABSTRACT

Abstract Epicardial cysts are rarer benign tumors than pericardial cysts. There have been few reports on surgical management of epicardial cysts. A 17-year-old normotensive boy presented with chest pain and palpitations, which on evaluation was found to be a mediastinal mass (pericardial cyst). Surgical resection of the cyst via thoracotomy was planned. The cyst was diagnosed as an epicardial cyst intraoperatively. However, due to the epicardial origin of cyst and posterior adhesions, resection was done via midline approach. The base was formed by visceral pericardium and eroding into myocardium of left ventricle, so the resection was concluded with on-pump surgery. In case of erroneous diagnosis or undesirable finding, a safer midline approach with on-pump surgery, as an alternative to minimally invasive approach for complicated epicardial cysts (erosion into ventricle/lying in close proximity to important structures or near to coronary arteries) should be considered.

ABSTRACT

RESUMEN El quiste pleuropericárdico es una lesión poco frecuente con un curso clínico benigno en la mayoría de los casos, que se detecta de forma casual en la radiografía de tórax. Mide aproximadamente entre 3 y 8 cm de diámetro. Su incidencia se ha estimado en uno por 100 000 casos y representa entre el 5 y el 10 % de los tumores mediastínicos. Un mayor número de ellos son congénitos, pero se han descrito algunos adquiridos debido a etiología infecciosa, inflamatoria o traumática. Los estudios imagenológicos y de elección son imprescindibles en su diagnóstico. Se presenta el caso de un paciente de sexo masculino con sintomatología clínica de insuficiencia cardiaca descompensada que acudió al Hospital General Universitario Dr. Gustavo Aldereguía Lima de Cienfuegos donde se le indicó rayos X de tórax. Se le realizó además tomografía de tórax simple y contrastada y ecografía de campo pulmonar derecho y abdominal. Se diagnosticó gran quiste pleuropericárdico predominantemente derecho, derrame pericárdico de gran cuantía, derrame pleural y ascitis de pequeña cuantía. Se presenta este reporte por la importancia que se le confiere a los estudios imagenológicos en el diagnóstico de las afecciones mediastinales, debido a su exactitud, para lograr una adecuada conducta a seguir a la hora imponer tratamiento y lograr el seguimiento de los pacientes afectados con esta patología.


ABSTRACT The pleuropericardial cyst is a rare lesion with a benign clinical course in most cases, which is detected incidentally on the chest radiograph. They are approximately 3 to 8 cm in diameter. The incidence of pleuropericardial cyst has been estimated at one per 100,000 cases and represents between 5 and 10 % of mediastinal tumors. A greater number of them are congenital, but some acquired due to infectious, inflammatory or traumatic etiology have been described. Imaging and choice studies are essential in its diagnosis. It is presented a case of a male patient with clinical symptoms of decompensated heart failure who attended the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos where a chest X-ray was indicated. A simple and contrasted chest tomography and right lung and abdominal field ultrasound were also performed. A predominantly right large pleuropericardial cyst, large pericardial effusion, pleural effusion and small ascites were diagnosed. This report is presented due to the importance on imaging studies in the diagnosis of mediastinal disorders, due to their accuracy, to achieve an adequate conduct to follow when imposing a treatment and monitoring of patients affected with this pathology.

ABSTRACT

Abstract Hydatid cystic disease is a significant clinical problem in endemic countries. Hydatid cysts are most commonly located in the liver and lungs. Primary mediastinal hydatid cyst is a rare clinical entity. The diagnosis must be considered in a patient with a mediastinal mass, particularly in endemic regions. Mediastinal hydatid cysts causing paralysis of phrenic and recurrent laryngeal nerves have been rarely reported. We describe a rare case of primary mediastinal hydatid cyst associated with diaphragmatic palsy caused by compression of the left phrenic nerve, which was successfully treated with partial cystectomy and capitonnage with hemidiaphragmatic plication.

ABSTRACT

@#Objective    To emphasize the important role of video-assisted thoracoscopic surgery (VATS) in treatment of mediastinal bronchogenic cysts (MBCs). Methods    We retrospectively reviewed the clinical data of 112 patients (53 males and 59 females) of mediastinal bronchogenic cysts who underwent VATS in our institution between April 2001 and Aprial 2016. Median age was 4–75 (45.6±15.0) years. All patients underwent chest CT preoperatively. The patients were divided into two groups: an anterior mediastinum group, 47 patients; a middle and posterior mediastinum group, 65 patients including 35 patients in the middle mediastinum, 30 patients in the posterior mediastinum. The average diameter was 0.5–22.0 (3.50±2.33) cm. The average CT attenuation was 0–67 (35.5±15.3) Hu on unenhanced CT. We began each operation with the VATS technique. Results    The CT diagnostic accuracy for group middle and posterior mediastinum with CT value≤20 Hu was higher than others (61.5% vs. 13.1%, χ2=17.675, P<0.001). A total of 111 patients underwent VATS, only one patient converted to open thoracotomy. Cyst resection and thymectomy were conducted in 45 patients, cyst resection and extended thymectomy were conducted in 2 patients in the anterior mediastinum group. Simply cyst resection were performed in the middle and posterior mediastinum group (n=65). The average operative time was 40–360 (104.5±43.1) min. The average intraoperative blood loss was 5–600 (57.9±88.9) mL. The intraoperative complication rate was 3.6% and the incomplete resection rate was 6.3%. The main reason for these was severe adhesion between the cyst and mediastinal structure. No serious postoperative complication was found. Follow-up was done in 99 patients, and the mean follow-up time was 42 (12–191) months. There was no local recurrence. Conclusion    VATS resection of MBCs is a safe and efficacious procedure, and minimally invasive and  surgical resection should be performed as early as possible for MBCs.

ABSTRACT

Thymic cysts are uncommon benign lesions in the anterior mediastinum. We here describe a 55-year-old male with spontaneous thymic cyst hemorrhage manifesting as a rapidly enlarging mediastinal mass that was resected completely with video-assisted thoracoscopic surgery. To the best of our knowledge, this is the first report of a spontaneous thymic cyst hemorrhage in Korea. In cases of rapidly enlarging mediastinal masses, spontaneous thymic cyst hemorrhage should be considered as a differential diagnosis.

ABSTRACT

PurposeTo explore the CT features and its diagnostic value of mediastinal congenital bronchogenic cysts.Materials and MethodsThe clinical findings and CT manifestations of 14 patients with mediastinal bronchogenic cysts confirmed by surgery and pathology were retrospectively analyzed, among which 12 were performed by both plain and enhanced CT scan, and the other 2 only received either plain or enhanced CT scan.ResultsAll the patients presentedfluid-filled cysts, and 3 of them had CT number lower than 20 HU, 7 cases from 20 to 60 HU, and 4 more than 60 HU. Four patients had lesions in anterior mediastinum, 4 others in posterior mediastinum, and all the 8 lesions were on the left side; 6 patients had lesions in middle mediastinum, among which 5 lesions were on the right side; and 1 case of posterior bronchogenic cysts cancerated into adenocarcinoma.ConclusionMediastinal bronchogenic cysts can appear in any part of mediastinum; lesions in middle mediastinum are more likely to occur on the right side, whilst lesions in anterior and posterior mediastinum are often located on the left side. The typical CT manifestations show well-defined round or oval masses of homogeneous soft-tissue or cysts with watery density.

ABSTRACT

Paciente do sexo feminino, 47 anos, admitida com queixa de dispneia aos pequenos esforços como único sintoma. Exames clínico, eletrocardiográfico e de laboratório normais. Radiografia de tórax demonstrou massa em base de hemitórax direito, que a tomografia computadorizada de tórax revelou tratar-se de massa cística bem delimitada, medindo cerca de 11,3 x 10,6 x 10,9 cm, sugerindo o diagnóstico de cisto pericárdico. A paciente foi submetida a toracotomia direita para ressecção do cisto. A paciente evoluiu sem intercorrências. O resultado do exame anatomopatológico, ao contrário do esperado, diagnosticou cisto tímico.


A 47-year-old woman was admitted with a history of dyspnea on mild exertion as her only symptom. Clinical exam, laboratory tests, and electrocardiography were normal. Chest X-ray demonstrated right hemithorax base mass, and CT scan revealed a well-defined cystic mass measuring approximately 11.3 x 10.6 x 10.9 cm, suggesting the diagnosis of pericardial cyst. The patient underwent right thoracotomy for resection of the cyst. The patient's progress- was uneventful. The result of histopathological examination, contrary to expectations, revealed thymic cyst.

ABSTRACT

Pericardial cysts occur rarely, with an incidence rate of 1 per 100,000. They are usually detected by chance and clinically silent in most cases. Pericardial cysts are the most common benign tumours of the pericardium and presents by the third or fourth decade of life, and equally common in males and females. In principle, they only require follow-up, however, an enlarging or symptomatic cyst requires surgical removal. We report a case of a 32 year-old Malay lady, who presented with history of recurrent pericardial effusion followed by right pleural effusion. Computed tomography (CT) thorax identified a large mediastinal cyst as the cause of her problem, requiring exploratory thoracotomy.

ABSTRACT

Primary thymic mucinous adenocarcinoma is an extremely rare aggressive subtype of thymic carcinoma. With a review of literatures, only nine cases have been reported up to present. A 36-year-old woman was admitted for further evaluation and treatment of a mediastinal mass. The patient had no medical history of cancer. The clinicoradiological examination disclosed no tumor elsewhere. After the surgical excision of mediastinal mass, it was grossly a round semi-solid mass with mucin-filled cystic areas. Microscopically solid areas showed cords, small nests and dilated glands infiltrating the fibrotic parenchyma, while the cystic areas were lined by mucinous epithelium with tumor cells floating in extracellular-mucin pools. Some cystic walls underwent malignant transformation of the benign thymic epithelium. Immunohistochemically, the tumor cells were positive for cytokeratin (CK) 7, CK20, CD5, and CDX-2, and negative for thyroid transcription factor-1. In conclusion, the mucinous thymic adenocarcinoma should be recognized as a separate histopathological entity and considered in the differential diagnosis of mediastinal carcinomas.

ABSTRACT

Cistos pericárdicos são raros, comumente congênitos, com localização mais frequente no ângulo cardiofrênico direito. O diagnóstico é suspeitado pela radiografia de tórax anormal. O presente relato descreve um caso de cisto pericárdico com aspecto radiográfico atípico, em um paciente atleta, manifestando-se clinicamente com sintomas de insuficiência ventricular direita. O diagnóstico foi sugerido pelo ecocardiograma transesofágico e confirmado pelo estudo anatomopatológico.


Pericardial cysts are rare, usually congenital. Cysts frequently occur in the right cardiophrenic angle and their diagnosis is usually suspected after an abnormal chest X ray. The present case report shows a case of pericardial cyst with atypical radiographic aspect in an athletic patient who presented clinical with symptoms of right ventricular failure. The diagnosis was suggested by echocardiogram and subsequently was confirmed by pathologic examination.

ABSTRACT

We report a case of a 46-year-old woman who presented with subacute exertional dyspnea and severe hypoxia. A large cystic mass compressing the right side of the heart along with right-to-left atrial shunt flow through an alleged atrial septal defect (ASD) were detected on echocardiography. CT scan of the chest and MRI of the heart revealed a loculated cystic mediastinal mass with hemorrhage measuring 5.5x8 cm compressing the right atrium and ventricle. The patient underwent cyst resection and primary closure of the ASD. This report illustrates a case of an unusual symptomatic pericardial mass compressing the right atrium and ventricle in a patient with an secundum ASD.

ABSTRACT

Hydatid disease is a significant health problem in endemic areas. While occurrence of the cysts in the liver and lung is common, mediastinal localisation is extremely rare. We report the case of a 35-year-old male who presented with a painless swelling on the right side of the neck and features of superior vena caval obstruction. Chest radiography and computed tomography (CT) suggested a cyst in the right upper lobe, extending into the right supraclavicular region as well as another cyst in the left lung. Thoracotomy revealed that the right-sided cyst was actually mediastinal in location and had herniated through the thoracic inlet compressing the superior vena cava (SVC). Both cysts were removed in two separate operations and symptoms of SVC compression subsided after removal of the right-sided cyst. Histopathology was consistent with a hydatid disease.

ABSTRACT

Pericardial cysts account for 12-18% of all mediastinal masses. They are usually asymptomatic and incidentally detected. However, when large, they can cause symptoms. Most pericardial cysts are located in the right cardiophrenic angle, but they can be anywhere in the mediastinum. We reported a pleuropericardial cyst torsion after physical stress, a very rare complication of this condition. The diagnosis was made by computed tomography and confirmed by video-assisted thoracoscopy.


Cistos pericárdicos constituem 12-18% de todas as massas mediastinais. Geralmente, são assintomáticos e detectados incidentalmente, podendo manifestar sintomas quando alcançam um tamanho aumentado. Na maioria das vezes, estão situados no seio cardiofrênico direito, mas podem ocupar outra localização no mediastino. Neste artigo, relatamos uma torção de cisto pleuropericárdico após esforço físico, uma complicação raríssima dessa condição, cujo diagnóstico foi realizado por meio da tomografia computadorizada do tórax e confirmado posteriormente por videotoracoscopia.

ABSTRACT

Paciente encaminhada de outro serviço com história de dor torácica aguda de forte intensidade com diagnóstico de hematoma intramural na aorta ascendente para correção cirúrgica. Após investigação diagnóstica, identificou-se tumoração cística no mediastino anterior, que envolvia toda a aorta ascendente e que produzia restrição ao enchimento diastólico do ventrículo direito. A análise histológica do tumor ressecado revelou o diagnóstico de cisto tímico. Objetivo deste relato é descrever tumoração mediastinal de baixa prevalência, que pode produzir imagem radiológica com características de hematoma intramural e resultar em conduta terapêutica equivocada.


Patient was referred to our Service with acute thoracic pain and diagnosis of intramural hematoma of the ascending aorta for surgical correction. The diagnostic investigation showed a cystic tumor involving the ascending aorta causing restriction of the right ventricular inflow. After resection, the histologic analysis disclosed the diagnosis of thymic cyst. The aim of this study is to describe a rare mediastinal tumor that may simulate a radiologic feature with characteristics of intramural hematoma and may result in a wrong therapeutic approach.
