Superior vena cava syndrome is a group of symptoms arising from reduced blood flow from the superior vena cava to the right atrium. The causes of superior vena cava syndrome can be malignant or benign. Nearly 95% of cases are, however, the result of malignant diseases. Superior vena cava syndrome is characterised by swelling of the face, neck or upper limbs with visible dilation of the veins in the neck or chest. Frequent symptoms are breathlessness and coughing. The treatment of the syndrome depends on the aetiology of the obstruction, the seriousness and prognosis of the disease. Treatment should begin as early as possible.

Primary mediastinal large B-cell lymphoma (PMLBCL) is a unique type of B-cell lymphoma probably arising from a putative thymic medulla B-cell. It constitutes 6-10% of all diffuse large B-cell lymphomas (DLBCL), occurring more often in young females. PMLBCL is characterized by a diffuse proliferation of medium to large B-cells associated with sclerosis and a degree of compartmentalisation. Its main molecular characteristics include: gains in 9p segments, p53 mutations, BCL-2 and MAL gene over-expression, somatic mutations of IgVH genes, BCL-6, PIM-1, PAX-5, RhoH/TTF, and c-MYC, and constitutional NF-kappaB activation. The gene expression signature of PMLBCL seems to be much closer to classic Hodgkin lymphoma than to DLBCL. PMLBCL is characterized by a locally invasive anterior mediastinal mass, often producing cough, chest pain, dyspnea, and superior vena cava syndrome. Most PMLBCL patients have stage I-II, bulky disease, with pleural or pericardial effusions in a third of cases. Systemic symptoms, mainly fever or weight loss, are present in <20% of cases; increased LDH levels are observed in 70-80% of cases. Treatment with CHOP regimen followed by radiation therapy was associated with a 5-year survival of 65%. Apparently better results have been reported with third-generation weekly alternating regimens followed by radiation therapy. Any recurrence is almost always seen in the first 2 years of follow-up, and distant relapses tend to involve extranodal organs. Features associated with poor prognosis are poor performance status, pericardial effusion, bulky disease, high serum LDH at diagnosis, and a compromised dose-intensity of anthracycline and cyclophosphamide.

Superior vena cava syndrome results from obstruction of flow through the vessel either by external compression or thrombosis. External compression by intrathoracic neoplasms is the most common etiology. Thrombosis of the vessel most often occurs in the setting of indwelling catheters or pacemakers. The diagnosis is suggested by the clinical manifestations of facial and upper extremity swelling, dyspnea, and cough. It is confirmed by CT scan showing the development of collateral flow around the lesion. In this report, we present a patient who developed superior vena cava thrombosis after undergoing a short period of central venous catheterization and a Whipple procedure for adenocarcinoma of the ampulla of Vater. The endothelial damage caused by the catheter, the low-flow state induced by the large fluid shifts during the operation, and the hypercoagulable state induced by malignancy fulfill Virchow's triad for venous thrombosis. To our knowledge, this is the first reported case of superior vena cava syndrome after the Whipple procedure with symptoms appearing after a shorter period of catheterization than previously reported in the adult literature.

We encountered 2 incidental cases of invasive thymomas at Jordan University Hospital, Amman, Jordan; during routine coronary artery bypass graft surgery between 2005 and 2008 with an incidence of 0.6%. Both patients presented with angina pain. None of the 2 patients had pressure symptoms (cough, shortness of breath or superior vena cava syndrome) or Myasthenia Gravis symptoms. Total thymectomy with dissection of perithymic fat was performed on both cases. No radiotherapy was given. No recurrence of the tumor was seen in 2 years follow up. These cases are presented to emphasize the occurrence of this tumor.

We report a case of an adult who developed superior vena cava syndrome because of cardiac hydatidosis. A 37-year-old man from Morocco developed progressive dyspnoea and cough. Cardiac hydatidosis was diagnosed because of both the typical radiological findings and the positive serology for echinococcosis. The patient was treated by surgery and albendazole without complications.

Malignant peripheral nerve sheath tumors (MPNST) are rare nervous tumors usually located in the posterior mediastinum in the paravertebral gutters. We report the case of a non-smoking 62-year-old man who was admitted with a 4 months history of cough, hoarseness and shortness of breath. Physical examination noted a superior vena cava syndrome. CT scan of the chest revealed a right anterior and middle mediastinal mass compressing the superior vena cava, the ascending aorta, the right pulmonary artery, invading the superior root of the pulmonary vein and the right auricle. Flexible bronchoscopy showed extrinsic compression of the right main bronchus, the right upper lobe bronchus and intermedius bronchus. The patient underwent surgical biopsy of the mass by mediastinoscopy. Histological examination revealed a malignant peripheral nerve sheath tumor. The patient received a single cycle of chemotherapy (ifosfamid-adriamycin). Clinical course was marked by the fast worsening of the dyspnea and the general state. Patient died three weeks after the cure of the chemotherapy. This case is original by the exceptional clinical presentation of MPSNT with a superior vena cava syndrome and the very rare location of this tumor in the anterior and middle mediastinum.

An 18 years female was admitted with right-sided chest pain, dry cough, and low-grade fever and weight loss for last 1 month. On examination, patient had features of superior vena cava (SVC) syndrome with right-sided pleural effusion. Chest X-ray showed mediastinal widening with nonhomogenous opacity mainly in the periphery of right upper and mid zone with right-sided pleural effusion. Ultrasonography thorax confirmed mild pleural effusion. Pleural fluid analysis showed lymphocytic, exudative, low adenosine deaminase with negative for Pap smear. Contrast-enhanced computed tomography (CT) thorax revealed large extensive nodular soft tissue lesion along right mediastinum as well as costal pleura, with enlarged pretracheal lymphadenopathy and SVC obstruction. CT guided Tru-cut biopsy report came as malignant epithelial tumor with polygonal shape, abundant eosinophilic cytoplasm and nuclei with prominent nucleoli suggestive of mesothelioma of epithelioid type. The tumor cell expressed calretinin, WT-1, and immunonegative for thyroid transcription factor-1.

Superior vena cava syndrome is a complex of symptoms developing as a result of disordered circulation in the superior vena cava system and impaired venous blood outflow from the upper part of the body. The classical signs of superior vena cava syndrome are cyanosis, swelling of the head, upper limbs and upper chest, dilatation of subcutaneous veins, apnea, hoarseness, cough, etc. Diagnostics of superior vena cava syndrome is based on chest X-ray and CT Superior vena cava syndrome is a rare condition and therefore usually unrecognized during the first examination of the patient.

Primary mediastinal large B-cell lymphoma (PMBL) is a lymphoma occurring in the anterior mediastinum starting from the cells B of the thymique medullary zone. This is a rare entity characterized by epidemiological, clinical and evolutionary peculiarities as well as by pathological and immunohistochemical peculiarities. We report a case series of 5 patients with diagnosed PMBL hospitalized in Pulmonology Department of Ibn Sina Hospital between January 2012 and May 2016. The average age was 34 years, the median of consultation time was 2 months. Reported symptoms were dyspnea, chest pain, dry cough; two patients suffered from superior vena cava syndrome. LDH level was high in 4 patients. Thoracic imaging showed an anterior mediastinal tissue processing in 5 patients. Histological diagnosis was based on ultrasound-guided transparietal puncture biopsy in 5 patients. The contribution of immunohistochemistry was decisive in all cases. Patients were sent to the National Institute of Oncology for therapeutic management. PMBL prognosis is reserved, it most commonly occurs in young women, which increases the need of aggressive therapy to improve survival rate.

The approach to an intrinsic cause of superior vena cava syndrome (SVCS) is usually difficult but rewarding. We report a case of a middle-aged man who presented with progressive oedema of the upper half of the body, dyspnoea, cough and weight loss for a 1-year duration. He was a non-smoker without prior hospitalisation. Chest radiography showed right-sided pleural effusion with an apparent normal superior mediastinum. Contrast-enhanced CT of the chest revealed a right atrial mass extending and completely obliterating to superior vena cava. The differentials were tuberculosis, invasive fungal granuloma, sarcoidosis, primary vasculitis, chronic venous thrombosis, cardiac sarcoma/lymphoma and metastatic thyroid tumour or thymoma. He underwent transvenous (femoral approach) biopsy of the mass and then cardiothoracic surgery after haemodynamic instability. Pathology showed invasive thymoma type B3. This case highlights the approach to an intrinsic cause of SVCS, a complication of the transvenous approach, and importantly a noble finding of venous spread metastasis.
