ABSTRACT

Objective:To evaluate the value of color Doppler ultrasonography in diagnosing primary squamous cell carcinoma of the thyroid(PSCCT).Methods:Ultrasound images of 13 patients from August 2010 to June 2019 in the Second Hospital of Hebei Medical University with PSCCT confirmed by surgery and pathology were analyzed retrospectively.The ultrasonographic features were summarized.Results:All of the cases were single lesion. 92.3%(12/13) of the lesions were hypoechoic on ultrasound, 69.2%(9/13) of the lesions were ≥5 cm in maximal dimension and occupied one lobe of the thyroid gland, 76.9%(10/13) of the lesions were irregular, 69.2%(9/13) of the lesions had unclear boundary, 61.5%(8/13) of the lesions broke through the thyroid capsule and showed invasive growth. Calcification was rare, 23.1%(3/13) of the lesions were accompanied by striated calcification, 7.7%(1/13) of the lesions were accompanied by eggshell calcification, 15.4%(2/13) of the lesions showed few blood flow, 53.8%(7/13) of the lesions showed moderate blood flow, 30.8%(4/13) of the lesions showed rich blood flow, 69.2%(9/13) of the lesions were detected higher vascular resistance spectrum, 53.8%(7/13) of the lesions exhibited cervical metastatic lymph nodes. The ultrasonographic features of metastatic lymph nodes were hypoechoic, the lymphatic hilum structures were absent, with cystic changes in the interior.Conclusions:The color Doppler ultrasound images of PSCCT have certain specific features, and the identification of its sonographic characteristics is helpful to improve the diagnosing level of PSCCT.

ABSTRACT

Purpose To investigate the diagnostic value of prenatal MRI in fetal intracranial hemorrhage (FICH). Materials and Methods The imaging and clinical data of 41 cases of FICH accepting MRI diagnosis were retrospectively analyzed. The hemorrhage location, signal characteristics and the associated intracranial abnormalities were observed. The pregnancy outcomes and clinical data after birth were followed up. The correlation between periventricular hemorrhage/intraventricular hemorrhage (PVH/IVH) classification and clinical outcomes was analyzed by combining prenatal risk factors. Results Forty-one cases of FICH were evaluated. There were 23 cases of multifocal cerebral hemorrhage and 18 cases of single focal hemorrhage. According to the bleeding site, the 41 cases were classified into PVH/IVH (33 cases), cerebral hemispheres near cortex hemorrhage (3 cases), cerebellar hemorrhage (2 cases), subdural hemorrhage (2 cases) and subarachnoid hemorrhage (1 case). Most of the FICH cases were in subacute period (36/41) and a few were in chronic period or forming encephalomalacia (5/41). The associated changes included ventriculomegaly, vascular malformation, agenesis of corpus callosum, agenesis of vermis, etc. Follow-up results showed that there were 25 cases of labor induction (autopsy after labor induction was performed in 3 cases), 16 cases were followed-up after birth. Among the 16 newborn, there was 1 case of PVH/IVH grade II fetus showing left ear hearing loss after birth, 1 case of grade II fetus showed dyskinesia within one year after birth, and 1 case of grade IV fetus showed unilateral limb movement disorder. The other 13 cases had no obvious neurological sequelae. Spearman correlation test of ranked data indicated that PVH/IVH classification was moderately correlated with birth outcome (r=0.689, P<0.05). Conclusion Prenatal MRI can evaluate the type and severity of fetal intracranial hemorrhage, and provide references for clinical diagnosis and treatment.

ABSTRACT

Objective: To explore the relationship between left coronary plaque character with the bifurcation angle and diameter by 256-slice CT angiography (CTA). Methods: A total of 387 consecutive patients who received CTA in our hospital were retrospectively studied. There were 102 patients with normal image including 60 male and 42 female at the mean age of (52.10 ± 9.65) years and 285 patients with left coronary plaque including 166 male and 119 female at the mean age of (55.65 ± 10.40) years. All patients were divided into 4 groups according to the plaque condition, Normal group,n=102 patients without plaque, Non-calciifcation group,n=137, Calciifcation group,n=79 and Mixed group,n=69. The patients with non-calciifcation plaque included 73 of mild stenosis and 57 of moderate to severe stenosis in proximal LDA. Left coronary bifurcation angle, proximal diameter and area were measured by multi-planar reconstruction (MPR) and the maximum density projection (MIP) techniques to analyze the relationship between the above indexes and plaque position, character, degree of local stenosis. Results: Left coronary bifurcation angle, the proximal diameter, area in LDA and LCX in 3 plaque groups were all larger than those in Normal group,P0.05, while in patients with moderate to severe stenosis, the bifurcation angle and diameter were larger in male than those in female patients,P<0.05. Conclusion: 256-slice CTA could objectively evaluate left coronary bifurcation angle, stenosis degree and plaque character, which are valuable for coronary artery disease prevention, diagnosis and treatment in clinical practice.

ABSTRACT

Objective To assess the CT characteristics of thoracoabdominal localized Castleman disease (LCD) in 55 cases and correlate with histopathologic features. Methods Fifty-five patients with LCD proved histopathologically in thorax ( n = 25 ) and abdomen ( n = 30 ) were collected during past 20 years. The unenhanced and contrast-enhanced CT were performed in all patients. Two radiologists reviewed CT images and the CT findings were analyzed simultaneously. Results In 54 patients with hyaline-vascular type ( n = 50 ) and mixed type ( n = 4 ) localized CD, the lesion typically presented as solitary mass (90. 7% , 49 cases), with irregular or lobular or infiltrative margin ( 83.3% , 45 cases),central calcification (38. 9%, 21 cases), marked enhancement (100% , 54 cases), focal non-necrosis low attenuation areas (72. 2%, 39 cases), lymphadenopathy (70.4%, 38 cases) and dilated feeding vessels adjacent to the mass (96.3%, 52 cases). One lesion with plasma cell type localized CD presented as a mass with irregular margin, mild enhancement and central necrosis. Four morphologic patterns wereclassified on CT, including solitary mass with well-circumscribed margin (n =4), irregular or lobular margin ( n = 30), infiltrative or halo-like margin ( n = 16 ), and multiple coalescent maasses ( n = 5 ). Conclusion CT features of thoracoabdominal localized CD are closely related to the location and pathological type. LCD with hyaline-vascular and mixed type has typical CT characteristics, while LCD with plasma cell type has no typical CT findings.

ABSTRACT

Objective To study the relatinonship between the regional cerebral blood flow (rCBF) and NF-kB expression in perihematoma region after intracerebral hemorrhage (ICH).Methods 27 healthy dogs were divided into control group (3 cases) and ICH group (24 cases) at random. The models of ICH were made by injecting self-blood into the frontal lobes. At different points (3 h, 6 h, 12 h, 24 h, 48 h, 72 h, 7 d and 15 d), the changes of rCBF in the region of perihematoma were observed by perfusion weighted imaging (PWI). Immunohistochemistry SP method was used to detect expressions of NF-kB. Immune positive cells were stained brown-yellow colour in the cytoplasm and/or nucleus, and NF-kB positive particles that transformed from cytoplasm to nucleus showed activation of NF-kB. Results In the region of perihematoma, PWI showed hypo-perfusion within 12h, reperfusion or hyper-perfusion from 12 to 24 h, and slightly hypo-perfution after 48h. NF-kB positive cells presented at 6 h, reached the peak from 12 to 48 h, decreased from 72 h to 7 d, nearly disappeared at 15 d. NF-kB positive cells mainly existed in the region of perihematoma. From 12 to 48 h, NF-kB expression was markedly in quantities of neurons and gliacytes. The activated NF-kB was clearly shown at the same time.Conclusions Cerebral ischemia and reperfusion in the region of perihematoma could induce expression of NF-kB, which was involved in the inflammatory and immune reaction and resulted in the ingury caused by cerebral ischemia and reperfusion.

ABSTRACT

Objective Percutaneous puncture of gasserian ganglion was guided by CT scan to improve the accuracy and reduce complications and to compare the efficacy of chemical mutilation with ethyl alcohol and adriamycin.Methods Ninety-two patients with primary trigeminal neuralgia (39 males, 53 females) aged 37-84 yrs were divided into two groups : A ethyl alcohol group ( n = 47) and B adriamycin group ( n = 45) . Secondary trigeminal neuralgia was excluded by preoperative CT scan. Percutaneous puncture of oval foramen was guided by CT and correct location of needle tip was confirmed by injection of contrast medium. 100% ethyl alcohol 0.5ml (group A) or 2% adriamycin 0.5ml was injected.Results The patients were followed up for 12 months after treatment. Neuralgia disappeared in 31 out of 47 patients in group A (alcohol group) and in 36 out of 45 patients in group B (adriomycin group) . Treatment failed in 13 patients in group A and 6 patients in group B, and was partly effective in the other patients. There were no severe side effects or complications. Conclusion Percutaneous puncture of gasserian ganglion guided by CT is effective and reduces complications. Adriamycin is more effective than ethyl alcohol for chemical mutilation.

ABSTRACT

Objective To evaluate the feasibility of CT staging for esophageal cancer. Methods A retrospective analysis of 304 patients treated,from Jan. 1996 to Dec. 1998 chiefly with radiotherapy(126 conventional radiotherapy,55-65 Gy/27-35 fx/5.5-7.0 w;178 late-course accelerated hyperfractionated radiotherapy ,55-60 Gy/33-36 fx/ 4.5 -5.5 w)complete with CT data before treatment was done. The long survival was compared with pre-therapy CT findings and CT staging. ResultsThe survival rate of stage T1+T2 was very significantly different from those lesion with stage T3,T4(? 2=12.90,P0.05).The survival rates of patients positive for lymph nodes or distant metastasis were lower. Conclusion CT staging is quite optimal for non-operable esophageal cancer in clinical staging,as it is conducive to predict the prognosis.
