ABSTRACT
Objective:To analyze distribution characteristics of facial port-wine stains and brain imaging features in children with Sturge-Weber syndrome (SWS) .Methods:Clinical and imaging data were collected from 22 children with confirmed SWS at Department of Dermatology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from July 2017 to August 2020, and retrospectively analyzed. The distribution characteristics of port-wine stains along the facial trigeminal nerve and brain imaging features were investigated in these children with SWS.Results:Among the 22 children, 10 were males and 12 were females. Their age ranged from 0.08 to 9.92 years, and the median age was 1.67 years. There were 13 cases of SWS type Ⅰ and 9 cases of SWS type Ⅱ. In terms of the port-wine stain type, 4 children aged from 0.50 to 2.17 years were diagnosed with pink port-wine stains; 14 children aged from 0.08 to 8.83 years were diagnosed with purple port-wine stains; 4 children aged from 4.92 to 9.92 years were diagnosed with thickened port-wine stains. Port-wine stains were distributed in the ophthalmic (V1) division of the trigeminal nerve in 22 patients, in the maxillary (V2) division in 20 patients, and in the mandibular (V3) division in 8 patients. There were 17 children with ocular abnormalities, aged from 0.08 to 9.92 years, including 11 with glaucoma, 5 with elevated intraocular pressure and 2 with visual impairment. Among the children with glaucoma, 7 developed glaucoma within 2 years of age, 8 suffered from unilateral glaucoma, and 3 from bilateral glaucoma, and glaucoma occurred on the same side as port-wine stains. Brain imaging abnormalities were observed in 12 children, and mainly included vascular malformations in the cerebral cortex involving the frontal, parietal, temporal and occipital lobes, as well as cerebral atrophy, punctate hemorrhage, calcification, sulcal widening, midline deviation and increased intraventricular choroid plexus vessels. Eleven children had symptoms of epilepsy and other neurological manifestations, including developmental delay, mental retardation and physical impairment.Conclusion:Port-wine stains distributed in the V1 and V2 divisions of the facial trigeminal nerve may indicate a higher risk of SWS, and ophthalmic and brain imaging screening as well as long-term follow-up should be performed.
ABSTRACT
Acute carbon monoxide poisoning can cause multiple organ damage due to hypoxia. In severe cases, it can be life-threatening and has a high fatality rate. Intestinal obstruction and thrombosis are rare complications of carbon monoxide poisoning. A case of carbon monoxide poisoning was reported. In addition to the central nervous system lesion, intestinal obstruction and lower limb thrombosis were also found. In the treatment of carbon monoxide poisoning patients, the clinician was able to treat the common complications, attention should be paid to gastrointestinal tract, thrombotic disease and other rare complications, so as to avoid missed diagnosis.

Ewing's sarcoma in the cervix is characterized by extremely rare occurrence,high degree of malignancy,and rapid progression.The diagnosis of this disease is based on pathology and immunohistochemistry. The main image of the case reported in this paper showed the cervical cyst with solid mass,large volume,and uneven density and signal,and the solid part can be strengthened in enhanced scanning.Because of the rapid growth,the lesion is prone to liquefaction necrosis and bleeding.Since the metastasis occurs early,timely diagnosis is essential.

Hemophilia B is a genetic disorder caused by coagulation factor Ⅸ(FⅨ) deficiency, mainly manifesting as joint, muscle and deep tissue bleeding. Hemophilia pseudotumor is a mass formed by soft tissue liquefaction and necrosis caused by repeated bleeding. Most pseudotumors occur in the bone and muscle. We report a case of hemophilia B with pseudotumor formation in the pelvis and abdomen, where lesion location is relatively rare. After active and effective hemostasis, the patient's hematuria symptom gradually improved. This case suggests that early and timely hemostatic treatment is crucial for patients with hemophilia.
ABSTRACT
Objective To investigate the clinical manifestations and imaging modality for the diagnosis of hepatic fasciola gigantica disease.Methods Thirty eight patients with abdominal pain were admitted in our hospital and underwent investigations with different imaging modalities.Thirty-eight cases underwent abdominal CT scan,among which 5 cases underwent follow-up with abdominal ultrasonography,10 patients with routine MRI scan and CT scan examination,and 2 cases with liver biopsy.Results Thirty-eight cases with CT scan showed the hepatomegaly,with decreased attenuation of the hepatic parenchyma,unclear boundaries.Thirteen cases showed decreased densities (suggesting hydroperitonium),including 10 cases with enhanced CT showed mild inhomogenous enhancement.Five cases with color doppler ultrasound showed inhomogenous hepatic echogenicity,and multiple liver parenchyma echogenecity showedirregular,cluttered cystic dark areas and spleenomegaly,among which two cases had evident hydroperitonium.Ten cases with MRI scan showed liver enlargement,abnormal diffuse signal of hepatic parenchymal lesions and splenomegaly.Two cases who underwent needle biopsy showed parasitic granulomas and necrosis,surrounded by a large number of monocytes andeosinophilic infiltration.Clinical manifestations:All cases were presented with fever,abdominal pain,liver tenderness,etc.Twenty-five cases presented with nausea,vomiting,loss of appetite,15 cases presented with ascites,5 cases presented with pericardial effusion,5 cases with lung parenchymal changes on CT,others showed generalised systemic edema and malena,very few patients had utricaria,itching and other symptoms.Conclusion CT and MRI scanning in patients suspected with human fasciola hepatica showed multiple small hepatic subcapsular abscess,of which some were clustered or tunnel-like.Combined with parasites,imaging manifestations are helpful for the early diagnosis.
ABSTRACT
Objective To investigate the clinical characteristics and imaging manifestations of AIDS complicated with disseminated Penicillium marneffei (PM) infection. Methods A total of 12 patients with AIDS complicated with disseminated PM infection were collected and the symptoms, signs, laboratory examination results and image manifestations of these patients were analyzed retrospectively. Results (1) The diagnosis of PM infection in all the 12 cases were confirmed by peripheral blood culture.All the 12 cases (100％) had irregular fever (38-41 ℃) and enlarged lymph nodes, 8 cases (66％) had skin rashes; 8 cases (66％) had hepatomegaly; 9 cases (75％) had splenomegaly while 8 cases (66％) had anemia. (2) Imaging manifestation: Five cases manifested bilateral pulmonary disseminated miliary nodular shadows or lattice signs; 1 case showed enlarged hilar lymph node and 2 zases showed patchy shadow with pleuritis. One case presented sub-pleural curve line shadow at the posterior part of the right lower lung,and adhesion between the intestinal wall and intestinal mesentery in mass form in the abdomen by CT examination. Conclusion Patients suffering from AIDS (CD4T lymphocytes ＜50/μ L) with impaired immunity might be susceptible to complication of disseminated PM infection, which presents mainly damage of multiple organs and symptoms such as fever; enlargement of liver,spleen and lymph nodes, as well as specific skin maculopapular rashes. Imaging manifestations in the lungs were revealed as miliary nodular shadows and lattice-like shadows. Intensified abdominal CT might reveal presence of several enlarged postperitoneal lymph nodes and intestinal adhesion in shape of cakes.
