RESUMO
A boy, aged 11 years, was admitted due to intermittent fever for 15 days, cough for 10 days, and "hemoptysis" for 7 days. The boy had fever and cough with left neck pain 15 days ago, and antibiotic treatment was effective. During the course of disease, the boy developed massive "hemoptysis" which caused shock. Fiberoptic bronchoscopy revealed a left pyriform sinus fistula with continuous bleeding. In combination with neck and vascular imaging examination results, the boy was diagnosed with internal jugular vein injury and thrombosis due to congenital pyriform sinus fistula infection and neck abscess. The boy was improved after treatment with temperature-controlled radiofrequency ablation for the closure of pyriform sinus fistula, and no recurrence was observed during the follow-up for one year and six months. No reports of massive hemorrhage and shock due to pyriform sinus fistula infection were found in the searched literature, and this article summarizes the clinical features, diagnosis, and treatment of this boy, so as to provide a reference for the early diagnosis of such disease and the prevention and treatment of its complications.

Double-chambered left ventricle (DCLV) is a rare congenital heart disease. A hypertrophic muscle bundle in the left ventricle may cause varying degrees of obstruction in the middle of the left ventricle, resulting in different clinical symptoms. Here, we report a patient with a history of repeated chest tightness who was misdiagnosed with coronary heart disease and ventricular aneurysm. After repeated ultrasound examinations, the patient was eventually diagnosed with DCLV, which was confirmed by magnetic resonance imaging and coronary angiography. This case highlights the necessity to improve the accuracy of DCLV diagnosis via echocardiogram.

AIMS: To investigate the radiological characteristics of the PHNENs on CT and MRI and improve the understanding of the image manifestations and preoperative diagnosis of the disease. BACKGROUND: Primary hepatic neuroendocrine neoplasms (PHNENs) are rare diseases, and most of the relevant studies are case reports. Characterized by no specific clinical symptoms, PHNENs not only have a low preoperative diagnosis rate with great difficulty in early diagnosis but are frequently misdiagnosed as primary hepatic cancer. OBJECTIVE: 15 PHNEN patients were enrolled, with 10 cases in the G2 stage and 5 cases in the G3 stage. METHODS: The imaging and clinicopathological information of 15 patients pathologically diagnosed with PHNENs was retrospectively reviewed. RESULTS: The average age of the patients enrolled was 46.14±18.24 years, and the average tumor size was 91.00±61.17 mm. 13 cases showed nodules or masses, 8 cases were located in the periphery of the liver, showing capsule depression and subcapsular effusion signs. CT enhanced scan showed heterogeneous and obvious enhancement in 9 arterial-phase cases, 2 cases in arterial and portal venous phases both saw mild enhancement; the enhancement degree of lesions in the G2 stage in the arterial phase was significantly higher than in the G3 stage. Gd-EOB-DTPA dynamic enhanced MRI was conducted on 3 cases, and scattered lesions with heterogeneous and slight hyperintensity were observed in the hepatobiliaryspecific lesions. Image manifestations showed diffuse lesions in 2 cases, with heterogeneous enhancement in the arterial phase and decreased enhancement in the portal venous phase by the dynamic enhanced scan. CONCLUSION: PHNENs were the imaging characteristics of PHNENs. The CT-enhanced scanning during the arterial phase may provide a certain reference for pathological grading (G2 and G3 grades). Gd-EOB-DTPA-enhanced MRI is helpful for PHNEN diagnosis.
RESUMO
Background and Purpose: Subjective cognitive decline (SCD) is recognized as a preclinical indicator of Alzheimer's disease (AD), and this stage provides a valuable time window for ultra-early intervention in AD. The aim of this study was to investigate the neurocognitive characteristics of SCD and its correlation with objective cognition, negative emotion and sleep quality in Chinese elderly. Methods: A total of 1200 volunteers aged 60 and older underwent Brief Elderly Cognitive Screening Inventory, Quick Cognitive Screening Scale for the Elderly, Generalized Anxiety Disorder-7, Patient Health Questionnaire-9, Pittsburgh Sleep Quality Index and Core Neuropsychological Test. According to the examination results, the participants were divided into healthy control (HC) and SCD groups. The neurocognitive function of SCD and its relationship with objective cognition, negative emotion and sleep quality were analyzed. Results: Compared with the HC group, the SCD group had similar global cognitive function but slightly impaired neurocognitive function. After adjusting for confounding factors such as age, sex, marriage, education and chronic disease, neurocognitive function (Picture-Symbol Matching: OR=0.167, 95% CI: 0.105-0.266; Word Stem Completion: OR =0.260, 95% CI: 0.131-0.514; Trail Making Test: OR=0.315, 95% CI: 0.178-0.560; Picture Recall: OR =0.278, 95% CI: 0.122-0.636), negative emotion (sub-depressive symptoms: OR=2.287, 95% CI: 1.483-3.527; sub-anxiety symptoms: OR=1.663, 95% CI: 1.079-2.563), and poor sleep quality (OR=2.138, 95% CI: 1.571-2.909) were significantly correlated with the occurrence of SCD. Conclusion: The study illustrates that SCD is closely related to objective cognition, negative emotion and sleep quality. Clinical evaluation and follow-up of SCD should fully account for these factors.
RESUMO
BACKGROUND: Extraskeletal osteosarcoma (ESOS) is a highly malignant osteosarcoma that occurs in extraskeletal tissues. It often affects the soft tissues of the limbs. ESOS is classified as primary or secondary. Here, we report a case of primary hepatic osteosarcoma in a 76-year-old male patient, which is very rare. CASE SUMMARY: Here, we report a case of primary hepatic osteosarcoma in a 76-year-old male patient. The patient had a giant cystic-solid mass in the right hepatic lobe that was evident on ultrasound and computed tomography. Postoperative pathology and immunohistochemistry of the mass, which was surgically removed, suggested fibroblastic osteosarcoma. Hepatic osteosarcoma reoccurred 48 d after surgery, resulting in significant compression and narrowing of the hepatic segment of the inferior vena cava. Consequently, the patient underwent stent implantation in the inferior vena cava and transcatheter arterial chemoembolization. Unfortunately, the patient died of multiple organ failure postoperatively. CONCLUSION: ESOS is a rare mesenchymal tumor with a short course and a high likelihood of metastasis and recurrence. The combination of surgical resection and chemotherapy may be the best treatment.
RESUMO
Background: EBV-associated smooth muscle tumours (EBV-SMTs) are uncommon neoplasms associated with immunodeficiency. The pathogenesis of EBV-SMTs is poorly understood. IL-2-inducible T-cell kinase (ITK), a member of the Tec family of tyrosine kinases, is the predominant Tec kinase in T cells. Researchers have shown that ITK is involved in the pathogenesis of autoimmune diseases and carcinogenesis, and the loss of ITK function due to mutation in patients can lead to EBV-associated lymphoproliferation. Multiple Epstein-Barr virus-associated smooth muscle tumours with ITK mutation have rarely been reported. Case presentation: A 6-year-old female child was admitted to the hospital due to recurrent bilateral hip pain for more than one year. Tumours were found in the lung, near the intracranial cavernous sinus and in the lumbar spine and paraspinal soft tissues by CT and MRI. The patient underwent vertebral tumour biopsy, which suggested low-grade myogenic or inflammatory myofibroblastic tumours, so the patient was given three courses of chemotherapy without symptom relief or mass reduction. The patient underwent lumbar mass resection, the pathological results indicated EBV-SMT, and a novel germline homozygous deletion mutation in the ITK gene was detected. The deletion mutation in this gene has not yet been reported and the clinical significance of the pathogenicity of the variant is unknown. Intrabronchial mass resection was performed under fibre bronchoscopy, and the pathological results indicated EBV-SMT. No significant recurrence or progression was observed after more than 2 years of follow-up. Conclusions: We present a rare case of multiple EBV-SMTs combined with ITK gene mutation. Some of the tumours were removed, and some were treated conservatively. There was no significant recurrence or progression after more than two years of follow-up. The optimal treatment regimen still needs to be further explored, and the relationship between ITK gene mutation at this locus and immunodeficiency and EBV-SMT warrants further investigation.
RESUMO
PURPOSE: To improve the understanding of hepatic carcinosarcoma (HCS) by analyzing radiological imaging data and clinicopathological features. MATERIALS AND METHODS: A retrospective analysis was performed on four patients with HCS confirmed immunohistochemically. The analysis included three males and one female, aged 29 to 64 years. Four patients underwent computed tomography (CT) scans, and one underwent magnetic resonance imaging (MRI) scans simultaneously. RESULTS: Three patients had a history of hepatitis B, cirrhosis or fibrosis, and two patients had schistosomiasis. Two cases tested positive for elevated serum carbohydrate antigen (CA) 19-9. The maximum diameters of the lesions ranged from 7.8 to 9.0cm. Pathologically, the carcinomatous and sarcomatous elements in two patients could not be classified, one of the patients had cholangiocellular carcinoma (CCC) and undifferentiated sarcoma, the other had hepatocellular carcinoma (HCC) and undifferentiated pleomorphic sarcoma (UPS). All tumors showed heterogeneous density/intensity, accompanied by vast cystic changes and necrosis, with two cases having cystic septations. Capsule formation was not identified. The margins of the radiological images showed irregular ring enhancement. One case presented continuous progressive enhancement, one case with "fast in fast washout" and two cases with "fast in late washout". Lymphonodus metastasis, satellite nodules, vascular embolism, and organ invasion (hepatic flexure of the colon) were identified. CONCLUSION: HCS is a rare, high-grade malignancy with poor prognosis. The preoperative diagnosis is expected to improve by carefully analyzing the imaging features of the patients in combination with their clinical characteristics. Radical resection and postoperative chemoradiotherapy can improve the survival rate of patients.
RESUMO
Among 78 laboratory-confirmed cases, we found two asymptomatic infections. One patient was discharged within 14 days after treatment. Another patient was discharged 25 days after treatment, and his RT-PCR test was still positive on the 15th day. We found that there may be virus carriers in the asymptomatic population with an epidemiological contact history. After 14 days of isolation, those with asymptomatic infection may still carry the virus, which means a risk of transmission, presenting a new challenge for the management of home isolation.

BACKGROUND: Adenoid cystic carcinoma (ACC) is a rare malignancy of epithelial origin. It involves a variety of histologic types and often has distant metastasis. ACC metastasis to the liver is rare and usually involves spread to other organs. CASE PRESENTATION: We report a case of liver metastasis from a submandibular gland adenoid cystic carcinoma 11 years after resection of tumor. The patient was admitted to our hospital due to a liver-occupying lesion found by abdominal B-ultrasound, CT and MRI. A metastasis was found only in the liver, and after discussion the patient was treated with surgery. This tumor was histologically consistent with the diagnostic criteria of ACC. The patient was followed up 24 months after surgery, and showed no recurrence in the liver parenchyma at the site of operation or other organs. CONCLUSIONS: ACC is a very rare tumor and its pathogenesis is not completely clear. There are few articles about the imaging findings of ACC in the liver, and so it was difficult for us to make a correct diagnosis in clinical practice. The diagnosis of ACC mainly relies on pathologic examination, so we summarize the correlation between imaging and pathology.
RESUMO
BACKGROUND: Inflammatory pseudotumor-like follicular dendritic cell (IPT-like FDC) tumors of the liver is an uncommon tumor with extremely low incidence. To date, the radiologic findings of this tumor in multiphase computed tomography (CT) and magnetic resonance imaging (MRI) imaging have not been described. CASE SUMMARY: Patient 1 is a 31-year-old Chinese female, whose complaining incidentally coincided with the finding of multiple liver masses. In the local hospital, an abdominal enhanced CT found two hypo-dense solid lesions, with heterogeneous sustained hypoenhancement, in the upper segment of the liver's right posterior lobe. In our hospital, enhanced magnetic resonance imaging (MRI) with hepatocyte-specific contrast agents showed a similar enhanced pattern of lesions with patchy hyperintensity in the hepatobiliary phase (HBP). The patient underwent surgery and recovered well. The final pathology confirmed an IPT-like FDC tumor. No recurrence was found on the regular re-examination. Patient 2 is a 48-year-old Chinese male admitted to our hospital for a huge unexpected hepatic lesion. A dynamic enhanced abdominal CT revealed a huge heterogeneous enhanced solid tumor in the right lobe of the liver with a size of 100 mm × 80 mm, which showed a heterogeneous sustained hypoenhancement. In addition, enlarged lymph nodes were found in the hilum of the liver. This patient underwent a hepatic lobectomy and lymph node dissection. The final pathology confirmed an IPT-like FDC tumor. No recurrence was found upon regular re-examination. CONCLUSION: When a hepatic tumor shows heterogeneous sustained hypoenhancement with a patchy enhancement during HBP, an IPT-like FDC tumor should be considered in the differential diagnosis.
