The Research Of Lung Tubercle CT Sign And Pathology Comparison

Objective: Through the review analysis 136 examples after between the pathology confirmation's isolatism lung tubercle's occurrence spot, the morphological character, the strengthened scope and the pathology organization's relevance, summarizes the different pathology organization's CT sign, for clinical enhances the lung tubercle diagnosis rate to provide the possibility.Data and Methods: This research collection after the pathology confirmation's isolatism lung tubercle 136 examples, utilizes the CT scanning technique, like the infection thin layer (or target sweeps), HRCT, the post-processing technology, the enhancement scanning and so on, since childhood the tubercle occurrence spot, the density, the shape, the strengthened scope aspect, the discussion isolatism lung tubercle's CT performance and the organization pathology type's relevance, and makes statistics processing, summarizes the different pathology organization's CT characteristic.Results: 136 example SPN patient, malignant tubercle 75 examples, adenocarcinoma 36 examples, scale cancer 32 examples, gland scale cancer 5 examples, carcinoid 2 examples. Benign tubercle 61 examples, including tuberculoma 39 examples, inflammatory tubercle 20 examples, hamartoma 2 examples, pulmonary cyst 3 examples. And, the carcinoid, the hamartoma and the pulmonary cyst case number are few, has not carried on statistics analysis, therefore the surplus case number is 129 examples finally.1. Morbidity age: above 40 years old in patient, scale cancer 30 examples, adenocarcinoma 32 examples, gland scale cancer 5 examples, tuberculoma 10 examples, inflammatory vacation lump 13 examples, hamartoma 1 example, pulmonary cyst 1 example; below 40 years old in patient, scale cancer 2 examples, adenocarcinoma 4 examples, gland scale cancer 0 examples, tuberculoma 29 examples, inflammatory vacation lump 7 examples, hamartoma 1 example, pulmonary cyst 2 examples. 2. Infection spot: (1) on right lung apex section: Scale cancer 5 examples, adenocarcinoma 4 examples, gland scale cancer 1 example, tuberculoma 5 examples, inflammatory vacation lump 1 example; (2) on right lung leaf segmentum posterius: Scale cancer 4 examples, adenocarcinoma 5 examples, gland scale cancer 0 examples, tuberculoma 6 examples, inflammatory vacation lump 1 example; (3) on right lung leaf segmentum anterius: Scale cancer 6 examples, adenocarcinoma 5 examples, gland scale cancer 0 examples, tuberculoma 0 examples, inflammatory vacation lump 0 examples; (4) right lung middle period: Scale cancer 2 examples, adenocarcinoma 2 examples, gland scale cancer 0 examples, tuberculoma 1 example, inflammatory vacation lump 4 examples; (5) under right lung blade babbitting section: Scale cancer 1 example, adenocarcinoma 2 examples, gland scale cancer 0 examples. Tuberculoma 7 cases, inflammatory pseudotumor 1 cases). (6) the right lower lobe basal segment: squamous cell carcinoma in 2 cases, adenocarcinoma in 6 cases, glandular squamous cell carcinoma in 2 cases, tuberculoma, 1 case with inflammatory pseudotumor in 3 patients, (7) on the left lung speckling posterior segment: squamous cell carcinoma in 3 cases, adenocarcinoma in 2 cases, glandular squamous cell carcinomas 0 case, tuberculoma 9 cases, inflammatory pseudotumor 1 cases). (8) left upper lobe PPK: squamous cell carcinoma in 3 cases, adenocarcinoma 3 cases, glandular squamous cell carcinomas 0 case, tuberculoma, 1 case with inflammatory pseudotumor 1 cases). (9) left upper lobe tongue section: squamous cell carcinoma in 2 cases, adenocarcinoma in 2 cases, glandular squamous cell carcinomas 0 case, tuberculoma 0 case, inflammatory pseudotumor 0 cases). (10) left lower lobes back section: squamous cell carcinoma, 1 case with adenocarcinomas, 1 case with glandular squamous cell carcinomas 0 case, tuberculoma 9 cases, inflammatory pseudotumor in 3 patients, (11) left lower lobes basal segment: squamous cell carcinoma in 3 cases, adenocarcinoma 4 cases, glandular squamous cell carcinoma in 2 cases, tuberculoma 0 case, inflammatory pseudotumor 5 cases.3. Tumors edge character, morphology and internal structure and accompany signs: (1) points YeZheng: squamous cell carcinoma in 30 cases of adenocarcinoma in 11 cases, glandular squamous cell carcinoma in 5 cases, tuberculoma, 1 case with inflammatory pseudotumor 0 cases). (2) burr levy: squamous cell carcinoma in 20 patients adenocarcinoma 27 cases, glandular squamous cell carcinoma in 3 cases, tuberculoma in 2 cases, inflammatory pseudotumor 1 cases). (3) vacuoles levy: squamous cell carcinoma in 8 cases, adenocarcinoma in 9 cases, glandular squamous cell carcinoma, 1 case tuberculoma in 2 cases, inflammatory pseudotumor 1 cases). (4) bronchial vascular bundles levy: squamous cell carcinoma in 16 cases of adenocarcinoma 20 cases and glandular squamous cell carcinoma in 2 cases, tuberculoma, 1 case with inflammatory pseudotumor 1 cases). (5) pleural sag levy: squamous cell carcinoma in 20 patients adenocarcinoma 30 cases, glandular squamous cell carcinoma in 3 cases, tuberculoma 5 cases of inflammatory pseudotumor in 3 patients, (6) calcification: squamous cell carcinoma in 2 cases, adenocarcinoma in 2 cases, glandular squamous cell carcinomas 0 case, tuberculoma 10 cases, inflammatory pseudotumor in 2 cases.4. Strengthening range: peripheral lung cancer in 60 s peak (CT value about 55. 99HU), n/med tuberculosis tumor 120 s peak (CT value about 26. 89HU), inflammatory pseudotumor 180 s peaked (CT value about 76. 58).Conclusion: (1) Onset ages, lung cancer occurs at least 40 years old (P 0.05), more tuberculoma are under 40 ages(P 0.05), inflammatory pseudotumor much at least 40 years old (P﹤0.05). (2) lesion, tuberculoma and more focused on two upper posterior segment and lower lobe speckling back section, pathogenesis parts are statistically significant (P < O.05), each pathologic types of small peripheral lung cancer in location on was statistically significant (P > O.05). (3) edge character, morphology and internal structure and signs, points YeZheng with signs,, burrs, blood vessels and bronchi vacuoles eigenvalue cluster signs, pleural sag levy to peripheral lung cancer most saw. (4) strengthening amplitude, peripheral lung cancer is moderate strengthening, n/med tuberculosis tumor is mild strengthening, inflammatory pseudotumor was significantly strengthen.
