Abstract Background Pericardial hematoma is blood accumulation in the pericardial space. Although rare, it could arise in various conditions, such as after cardiac surgery. Clinical diagnosis of pericardial hematoma is implausible; thus, cardiac imaging plays a pivotal role in identifying this condition. We presented a case of multiple pericardial hematomas, which was found as an incidental finding in post-cardiac surgery evaluation. We highlighted the diagnostic challenge and the key features of multi-modality cardiac imaging in pericardial hematoma evaluation. Case presentation An asymptomatic, 35-years old male, who underwent surgical closure of secundum atrial septal defect (ASD) one month ago, came for routine transthoracic echocardiography evaluation. An intrapericardiac hematoma was visualized at the right ventricle (RV) 's free wall side. Another mass with an indistinct border was visualized near the right atrium (RA). This mass was suspected as pericardial hematoma differential diagnosed with intracardiac thrombus. Cardiac computed tomography (CT) scan showed both masses have an attenuation of 30–40 HU; however, the mass's border at the RA side was still not clearly delineated. Mild superior vena cava (SVC) compression and multiple mediastinal lymphadenopathies were also detected. These findings are not typical for pericardial hematomas nor intracardiac thrombus; hence another additional differential diagnosis of pericardial neoplasm was considered. We pursued further cardiac imaging modalities because the patient refused to undergo an open biopsy. Single-photon emission computer tomography (SPECT)/CT with Technetium-99 m (Tc-99 m) macro-aggregated albumin (MAA) and Sestamibi showed filling defect without increased radioactivity, thus exclude the intracardiac thrombus. Cardiac magnetic resonance imaging (MRI) reveals intrapericardial masses with low intensity of T1 signal and heterogeneously high intensity on T2 signal weighted imaged and no evidence of gadolinium enhancement, which concluded the diagnosis as subacute pericardial hematomas. During follow-up, the patient remains asymptomatic, and after six months, the pericardial hematomas were resolved. Conclusion Pericardial hematoma should be considered as a cause of pericardial masses after cardiac surgery. When imaging findings are atypical, further multi-modality cardiac imaging must be pursued to establish the diagnosis. Careful and meticulous follow-up should be considered for an asymptomatic patient with stable hemodynamic.

Superior vena cava syndrome is a life-threatening condition. Typically, the clinical presentations are gradual; hence, the diagnosis is often delayed until critical compression or obstruction has occurred. Pericardial hematoma is a rare condition that could occur after cardiac surgery. An asymptomatic, 25-year-old female, who underwent surgical atrial septal defect closure 5 days ago, was sent for routine echocardiography examination before discharge. An intrapericardiac hematoma was detected at the right atrium’s free wall without any intracardiac hemodynamic consequences. The patient was discharged and planned for monthly evaluation. During follow-up, the intrapericardiac hematoma was expanding. In the third month’s follow-up, the patient complained of shortness of breath, headaches, and coughs. Echocardiography evaluation revealed enlarged pericardial hematoma, which compressed the right atrium and superior vena cava orifice, without echo’ sign of cardiac tamponade. Computed tomography scan revealed superior vena cava compression by the pericardial hematoma and appearance of the collateral vessel. The patient was diagnosed with superior vena cava syndrome and sent for surgical evacuation. Pericardial hematoma after cardiac surgery should be evaluated meticulously. Chronic expanding hematoma could cause superior vena cava syndrome, which is fatal. Early diagnosis and appropriate treatment are essential in managing this condition.

Abstract Background Global aphasia without hemiparesis (GAWH) is a rare stroke syndrome characterized by the dissociation of motor and language functions. Here, we present a case of GAWH with the patient later regaining speech fluency. Case presentation A 73-year-old man was admitted to our emergency department immediately after an episode of syncope. On arrival, we noted his global aphasia but without any focal neurologic signs. Computed tomography (CT) perfusion scans showed a large hypodense region over his left perisylvian area. Under the impression of acute ischaemic stroke, he received recombinant tissue plasminogen activator (rtPA) injection and was treated as an inpatient. The patient was later discharged with GAWH status and received regular speech rehabilitation. After 14 months of rehabilitation, the patient gradually recovered his language expression ability. The degree of aphasia was evaluated with the Concise Chinese Aphasia Test (CCAT), and we obtained brain single photon emission computed tomography (SPECT) scans to assess cerebral blood flow. Conclusion A patient with severe impairments of Broca’s and Wernicke’s areas was able to talk fluently despite being unintelligible. SPECT revealed relative high level of radioactivity uptake in the right frontal lobe, suggesting the deficits in speech fluency could have been compensated by the right hemisphere. Although this is a single case demonstration, the results may strengthen the role of the right hemisphere in GAWH patients and suggests additional study that examines the possible benefits of stimulating activity at right homologous regions for recovering language function after global aphasia.

Objectives: Scimitar syndrome is a combination of rare congenital cardiopulmonary anomalies that can occur in 3% to 6% of patients with a partial abnormal venous connection. The presence of accompanying cardiac anomalies in these patients and in cases such as severe hypoplasia of the right lung or accompanying pulmonary artery hypertension necessitate early surgery in early infancy. Patients and Methods: 9 patients with scimitar syndrome operated on in our pediatric cardiac surgery clinic from 2012 to 2020 were retrospectively examined in our study. The ages of the patients ranged from 1 to 47 years, with a mean of 18.11±14.44. 1 patient died and mortality was 11.11%. Of the patients, 4 were male (44.44%) and 5 were female (55.56%). Patients' pulmonary arterial pressure ranged from 0.15 to 94 mmHg, with a mean of 39.22 ±22.49. Results: Close to 25% scimitar vein stenosis or scimitar vein drainage occlusion has been reported in the postoperative period, mostly in the newborn group in the literature. 2 patients had non-critical stenosis during the 3rd year follow-up despite the absence of stenosis orocclusion during the first 2 years of follow-up of 9 patients we followed. Their surgical follow-up is still ongoing since they are asymptomatic. Conclusion: As a result, the course of the disease depends on the follow-up of the patient, the timing of the surgery, and the quality of the anastomosis. The follow-up and treatment of these patients will be more accurate in advanced centers experienced in scimitar surgery.

Thorough study is required to decide the appropriate management of hepatic tumors in children. We present a case report of a hepatic embryonal undifferentiated sarcoma with unfavorable prognosis in a nine-year-old girl. After undergoing a detailed cancer characteristics and extension study, a two-stage surgery approach was decided. The hepatic tumor resection was the first procedure to be performed. One week later, under cardiopulmonary bypass, deep hypothermia, and circulatory arrest, thrombectomy of the inferior vena cava and right atrium was accomplished, plus thromboendarterectomy of the right pulmonary artery. During a four-year follow-up, the patient continues to be disease-free.

We studied a 79-year-old woman within 3 h of the onset of a motor aphasia and a right hemiparesis. Single photon emission computed tomography (SPECT) showed a 24% decrease in the perfusion of the left middle cerebral artery territory and a 16% reduction in the perfusion of the right cerebellum. A mild naming difficulty was the neurological deficit at the end of the SPECT examination, and complete recovery was achieved within 24 h. Repeated SPECT study 10 days later was normal. This is the first report of focal hemispheric and contralateral cerebellar hypoperfusion in transient cerebral ischemia.

Regional cerebral blood flow (CBF) was studied in 16 normal adult volunteers during rest and in 10 the study was repeated during skilled hand movements. A fast-rotating (“dynamic”), single-photon emission computerized tomograph (ECT) with four detector heads was used. Xenon-133 was inhaled over a 1-min period at a concentration of 10 mCi/L. The arrival and washout of the radioisotope was recorded during four 1-min periods. Two slices, 2 cm thick, 7 and 12 cm above the orbitomeatal line were obtained in every study. CBF averaged 60 ml/100 g/min (SD ± 11) in the lower slice and 51 ml/100 g/min (SD ± 13) in the upper slice. A symmetric pattern comparing right to left sides was found in both slices. Finger tapping and writing with the right hand increased CBF in specific areas of the upper slice: in the contralateral hand area by 35 ± 15% ( p < 0.025), and in the supplementary motor area on both sides by 34 ± 15% ( p < 0.025).

In this project, we recruited a sample of 150 patients with first episode of psychosis with schizophrenia features (FEP) and 100 healthy controls. We assessed the differences between these two groups, as well as the changes between the acute phase of illness and subsequent remission among patients over 18-month longitudinal follow-up. The assessments were divided into four work packages (WP): WP1- psychopathological status, neurocognitive functioning and emotional recognition; WP2- stress response measured by saliva cortisol during a stress paradigm; cerebral blood perfusion in the resting state (with single photon emission computed tomography (SPECT) and during activation paradigm (with Transcranial Ultrasonography Doppler (TCD); WP3-post mortem analysis in histologically prepared human cortical tissue of post mortem samples of subjects with schizophrenia in the region that synaptic alteration was suggested by WP1 and WP2; WP4- pharmacogenetic analysis (single gene polymorphisms and genome wide association study (GWAS). We expect that the analysis of these data will identify a set of markers that differentiate healthy controls from patients with FEP, and serve as an additional diagnostic tool in the first episode of psychosis, and prediction tool which can be then used to help tailoring individualized treatment options. In this paper, we describe the project protocol including aims and methods and provide a brief description of planned post mortem studies and pharmacogenetic analysis.

Urinary Metanephrines

Abstract Introduction: PPGLs are rare neuroendocrine tumors that arise from chromaffin cells of the adrenal medulla or their neural crest progenitors, being able to secrete catecholamines. Its treatment is primarily surgical; however, for metastatic/inoperable tumors, effective treatments are lacking. The use of TMZ, an oral alkylating agent, has been scarcely reported with variable response rates. We report 2 patients with reasonable clinical, biochemical and structural responses. Case Reports: Case 1) A 14-year old girl presented with neck pain, sweating, hypertension and tachycardia. Urinary hormonal profile revealed metanephrines 80 (up to 320 ug/24h) and normetanephrines 2983 (up to 390 ug/24h). Abdominal MRI showed a 10x6x5 cm retroperitoneal lesion in close contact with celiac trunk, superior mesenteric artery, renal arteries, aorta, left renal vein and vertebral bodies of T10, T11 and T12. A chest CT revealed multiple lung metastases. After 11 months, both the primary abdominal lesion and lung metastases increased in size.. Due to disease severity, after excluding surgical possibilities and confirming diagnosis by lesion biopsy, rescue treatment with TMZ was started for 5 days on a 28-day cycle. After 11 cycles, lung and abdominal lesions decreased more than 30% in size, and urinary metanephrines decreased 53.4%. After 21 cycles, there is no evidence of disease progression. Case 2) A 44-year old female was first diagnosed at the age of 31 with a right adrenal mass invading the kidney and the inferior vena cava associated with hypertension, sweating, headaches and palpitations. She underwent right adrenalectomy and nephrectomy. Immunohistochemistry confirmed the diagnosis of pheochromocytoma. Seven years later, follow-up CT`s showed a 3 x 2 cm liver metastasis, which was resected, and two lung lesions, one located at the right inferior lobe (1.6 cm) and the other at the left superior lobe (0.9 cm), which initially were just followed-up. At this time, a 7-month sorafenib trial was performed but the drug was stopped due to intolerable side effects. After 3 years of follow-up, the lung lesions increased in size and the right lesion was resected, but the patient refused surgery for the remainder left lung lesion. After 1 year, left lung lesion increased to 2.4 cm and mediastinal and paratracheal lymphadenomegaly developed. TMZ in the same aforementioned schedule was prescribed and after 7 cycles a new chest CT revealed complete regression of the lung and lymph node metastases.. Urinary metanephrines were 2.1 times the upper limit of normal before TMZ and decreased to normal range. Conclusion: These cases highlight the promising role of a well-tolerated single drug chemotherapy regimen in severe cases of metastatic and inoperable PPGLs. TMZ could be considered an alternative strategy for the treatment of these cases and, if possible, should be tested in adequate clinical trials.
