ABSTRACT

Objective To investigate the clinical value of CT lymphangiography (CTL) combined with direct lymphangiography (DLG) in primary intestinal lymphangiectasia (PIL). Methods Sixteen patients diagnosed as PIL with intestinal enteroscopy were recruited in this retrospective study. All the patients were performed DLG and CTL one week before exploratory laparotomy. Subjective assessment in DLG included weak lymphatic fluid drainage, lymphangiectasia, lymphatic reflux, fistula and thoracic outlet reflux or obstruction. While for CTL combined with DLG, the intestinal and extra-intestinal lesions were evaluated, including lymph node, edema, lymphangiectasia and abnormal distribution, fistula, and lymphangiomatosis. All the diagnosis was compared with intestinal endoscopy results. Results For DLG, 16 weak lymphatic fluid drainages, 9 lymphangiectasia, 1 fistula with abdomen and 14 thoracic outlets weak lymphatic fluid drainage or obstruction were found. For DLG combined with CTL, 16 intestinal lumens dilatation and 14 circumferential intestinal thickening were found in intestinal lesions. While for extra-intestinal lesions, the imaging features included edematous findings (12 in mesentery, 7 ascites only, 2 hydrothorax and ascites, and 3 pericardial, thoracic and abdominal effusions), abdominal lymph nodes (6 cases), lymphangiectasia and abnormal distributions (14 cases), fistulas (lymph-intestinal luminal fistula in 4 cases, and lymph-abdominal fistula in 3 cases), lymphangiomatosis (3 cases), and thoracic duct outlet dysfunction and reflux (14 cases).The number of cases diagnosed as intestinal lymphangiectasia, intestinal luminal lymph exudation and lymph fistula were 16, 10 and 6 with intestinal endoscopy, while the number were 11, 0, and 4 with CTL combination with DLG. Conclusion Combination of CTL with DLG is valuable in the diagnosis of PIL.

ABSTRACT

Objective To evaluate the value of imaging examinations in the treatment of lymphangioleiomyomatosis (LAM) with chylothorax by thoracic duct extremity exploration.Methods Data of 34 LAM with chylothorax confirmed by pathology and clinical diagnosis were retrospectively analyzed.All patients underwent 99Tcm-DX lymphoscintigraphy and CT lymphangiography (CTL).Thoracic duct lesion types of 99Tcm-DX lymphoscintigraphy were type Ⅰ (abnormal concentration pattern),type Ⅱ (ectopic drainage pattern),and type Ⅲ (without image or transient image pattern).The type Ⅰ and type Ⅱ were diagnosed as thoracic duct abnormalities.Thoracic duct lesion types of CTL were type Ⅰ (dilatation pattern),type Ⅱ (distal obstruction pattern),type l (truck constriction pattern),type Ⅳ (ectopic drainage pattern),and type Ⅴ (no-display pattern).Type Ⅰ-Ⅳ were diagnosed as thoracic duct abnormalities.Consistency of displaying thoracic duct abnormalities between 99Tcm-DX lymphoscintigraphy and CTL was evaluated.Results The thoracic duct abnormalities in 99Tcm-DX lymphoscintigraphy were 58.82% (20/34;type Ⅰ in 17,type Ⅱ in 3,type Ⅲ in 14),and in CTL were 73.53% (25/34;type Ⅰ in 15,type Ⅱ in 3,type Ⅲ in 5,type Ⅳ in 2,type Ⅴ in 9).The consistency of CTL and 99Tcm-DX lymphoscintigraphy for detecting thoracic duct abnormalities was good (Kappa=0.679).In CTL thoracic duct types,type Ⅰ and Ⅱ were operated by thoracic duct-venous anastomosis or thoracic duct extremity release operation,type Ⅲ was operated by thoracic duct adhesion or compression band release operation,operative approach and method were chosen according to the abnormal thoracic duct flow path in type Ⅳ,type Ⅴ was took conservative treatment.Conclusion CTL is superior to 99Tcm-DX lymphoscintigraphy,which can clearly display the type of thoracic duct lesion and provide imaging informations to choose operation methods in thoracic duct exploration treatment for LAM with chylothorax.

ABSTRACT

Objective To evaluate the value of magnetic resonance thoracic ductography (MRTD)and magnetic resonance (MR) pelvic scanning in the chylous leakage of female reproductive system.Methods A retrospective evaluation of the imaging findings of MRTD and MR pelvic in 7 patients was performed,and compared with direct lymphangiography (DLG),lymphoscintigraphy and surgery.Results The rate of thoracic duct visualization in DLG was 71 .4% (5/7 ).The rate of venous angle visualization inlym-phoscintigraphy was 71.4% (5/7).The rate of thoracic duct visualization in MRTD was 100% (7/7).Except for 1 case withgeneral-ly normal findings,the remaining 6 cases showedobstruction of the thoracic duct in MRTD.Among those cases,bilateral drainage was found in 1 case,right thoracic ductwas seen in 1 case,multiple tortuous dilated lymphatic channelsaround the venous angle was detected in 4 cases,and multiple lymphangiomas was seen in 1 case.All of the 7 patients were conducted by surgery.6 cases were confirmed as obstruction of the thoracic duct.MRTD & MR pelvic found more multiple lymphangiomas lesions and detected 2 cases with bone abnormalities.Conclusion MRTD combined with MR pelvic could provide more comprehensive assessment of female re-productive system chylous leakage.It should be used as routine examination before operation.

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.
