1 Lung; Inflammatory pseudotumor; X-ray; Computed tomography Imaging diagnosis.

2 Objective To research imaging characteristic of pulmonary inflammatory pseudotumor.

3 Pulmonary inflammatory pseudotumor; Misdiagnosis; Type; Reason.

4 Tumor type:Pseudotumor looked like oval bump with uniformity signal, laying in muscle wimble, and it circled optic nerve, but the optic nerve was clear.

5 Hemophilic pseudotumor showed a mixed signal in both T1WI and T2WI, which was composed of hematoma surrounded by fibrous membrane.

6 A case of inflammatory pseudotumor ( IPS ) of the urinary bladder is described.

7 Conclusions Demyelinating pseudotumor is characterized by perivascular lymphocytes and diffusely distributed macrophages, while the lesion is usually observed with a texture of areosis change.

8 Fibrous pseudotumor is not uncommon in other sites of the body, but rarely occurs on the testicular tunica albuginea.

9 Inflammatory pseudotumor of lymph nodes ( IPT - LN ) represents an unusual cause of lymphadenitis of unknown etiology.

10 Other rare complications include premature cataracts, pseudotumor cerebri, and calcifications of the basal ganglia .

11 False-positive results mostly are caused by the inflammatory pseudotumor, analysis of its time-attenuation curve could help differentiate from the malignant nodule.

12 Awareness of the MRI features of the fibrous pseudotumor is important and could prevent unnecessary orchiectomy .

13 Materials and Methods:50 cases of orbital inflammatory pseudotumor proved by pathology or treatment (antibiotics and steroids) in our hospital from 1984 to 1995 were analysed.

14 The reticular lymphoducts in the perimeter of the pulmonary squamocellular carcinoma tissue was higher than that in the interior and the pulmonary inflammatory pseudotumor.

15 Objective To study the CT signs of the orbital inflammatory pseudotumor.

16 Objective To investigate the pathogenesis and clinical treatment of pulmonary inflammatory pseudotumor (PIP).

17 Musculoskeletal manifestations of hemophilia include hemophilic arthropathy and hemophilic pseudotumor.

18 Conclusion CT scan is of important role in diagnosing and differential diagnosing orbital inflammatory pseudotumor.

19 The density of single lumen lymphoducts was much higher than that of collapsed and reticular lymphoducts in the pulmonary inflammatory pseudotumor.

20 Conclusions We conclude that low dose of RT by using linear accelerator is a safe and effective way for palliating symptoms of idiopathic orbital inflammatory pseudotumor.

21 Objective To investigate the clinicopathological features of liver inflammatory pseudotumor (LIP).

22 Objective:To explore the value of CT in the diagnosis of inflammatory pseudotumor of the liver.

23 Primary hepatic carcinoma, hepatic metastases, focal nodular hyperplasia, and inflammatory pseudotumor were presented as different MR features on each phase of MRSP.

24 Conclusion CT examination is very helpful to the correct diagnosis of pulmonary inflammatory pseudotumor.

25 Results Of 124 cases, there were 74 cases with peripheral pulmonary carcinoma, 42 centric pulmonary carcinoma, 4 inflammatory pseudotumor, 2 tuberculosis, 1 lymphoma and 1 chondromatous hamartoma.

26 Conclusions: Operation with corticosteroid is an effective means for the treatment of orbit inflammatory pseudotumor.
