ABSTRACT
Purpose To explore the clinical features and multi-slice spiral CT (MSCT) imaging characteristics of nodule-type and mass-type parotid eosinophilic lymphogranuloma,in order to improve the understanding of the disease.Materials and Methods The clinical and imaging data of 6 patients with nodule-type or mass-type parotid eosinophilic lymphogranuloma confirmed by surgery pathology in Chongqing Jiulongpo Chinese Medicine Hospital from June 2007 to March 2016 (experimental group) were retrospectively analyzed.Another 32 synchronous patients with Warthin tumor confirmed by surgery pathology were enrolled as the control group.MSCT conventional and enhanced scanning were performed on all these patients,and the clinical features and MSCT characteristics were compared between the two groups.Results Compared with patients with Warthin tumor,the value and percentage of peripheral eosinophil and serum IgE level increased in all the 6 patients (age ＜ 50) with eosinophilic lymphogranuloma,and the difference was statistically significant (P＜0.01).Compared with Warthin tumor,eosinophilic lymphogranuloma was often accompanied by ipsilateral parotid enlargement,neck deep fascia thickening and edge blurring,lesions reducing,and neck lymph node enlargement.The enhanced scanning of eosinophilic lymphogranuloma showed delayed enhancement,and the enhancement in venous phase and delayed-phase was significant;while Warthin tumor showed significant enhancement in arterial phase and contrast clearing features in delayed-phase.Conclusion The MSCT findings of eosinophilic lymphogranuloma characterized by nodules or masses shows features of inflammatory lesions,in which mass density is relatively uniform and presents delayed enhancement.Combining clinical manifestation with laboratory tests will contribute to distinguish eosinophilic lymphogranuloma and Warthin tumor.
ABSTRACT
Purpose To investigate the correlation of CT features with peripheral blood eosinophil count and proportion in eosinophilic gastroenteritis (EG).Materials and Methods Seventeen cases of clinically confirmed EG were retrospectively analyzed.The lesions were observed based on CT findings,and the count and proportion of peripheral blood eosinophil were calculated.Results Among 17 cases of EG patients,2 cases had one lesion,the peripheral blood eosinophil count and proportion of which were (0.28±0.22)× 109/L and (4.85 ± 2.19)％,respectively;5 cases had two lesions,the eosinophil count and proportion of which were (3.19± 1.82)× 109/L,(37.04± 11.36)％,respectively;6 cases had three lesions,the eosinophil count and proportion of which were (3.93 ±2.37)× 109/L and (45.22±22.99)％,respectively;3 cases had four lesions,the eosinophil count and proportion of which were (6.48±0.34)× 109/L and (75.83± 9.33)％,respectively;1 case had seven lesions,the eosinophil count and proportion of which were 8.87× 109/L and 75.60％,respectively.Conclusion There is a certain correlation of the peripheral blood eosinophil count and proportion with EG lesions.When the count and proportion of peripheral blood eosinophil increase significantly,the range of lesions may become more extensive,which suggests the scope of endoscopy or imaging examinations should be expanded in clinical work.
ABSTRACT
Objective To investigate diagnosis and treatment of venous cerebral infarction.Methods The reasons, clinical findings, imaging characters, treatment methods and prognosis of 19 patients diagnosed venous cerebral infarction were analyzed.Results The most frequent symptoms were headache, focal deficits, epilepsy, increased CSF pressure.Among 19 cases, multiple cerebral lesions were found in 12 cases, lobes lesions in18 cases, cerebral infarction with hemorrhage in 3 cases. After various treatments, 16 patients were discharged and one patient died and 2 patients gave up treatment. Conclusions Venous cerebral infarction has complicated causes, non-specific chinical manifestations and characteristic MR images. Anticoagulation and thrombolysis treatment in early stage may have good therapeutic effect.
