A case of inflammatory pseudotumor of the entire lung In a 61-ycar-old man is prcscntcd. The respiratory symptoms developed 2 months ago and progressed rapidly and the diagnosis of chronic pneumonia with ateletectasis of the entire lung, destroyed lung by tuberculosis and sepsis hAd to be ruled out The operative finding was different from our expectation. This case suggests that the Inflammatory pseudotumor can manifest as a whole lung-involving ass. Inflammatory pseudotumor is a nonneoplastic reactive pulmonary mass lesion that resembles tumor but shows little or no growth. Thc inflammatory pseudotufor usually present as a solitary round lung mass but in this casts progressed rapidly and destroyed the whole lung, which is rare. The patient was discharged with no problem and with outpatient followup.

Inflammatory pseudotumors (IPTs) are uncommon, mass-forming lesions, predominantly involving the lung and orbit. Although the incidence of IPTs is rare in the abdomen and pelvis, they can be encountered as enhancing, soft-tissue lesions, mimicking malignancy or fibrosclerosing disease. Generally, they exhibit a wide range of nonspecific imaging features in various organs. Preoperative imaging diagnosis of IPTs in appropriate clinical settings may help determine proper patient management. In this article, we review radiologic findings of IPTs in the abdominopelvic cavity, including the liver, spleen, kidney, gastrointestinal tract, mesentery, pelvis, and retroperitoneum.

Hepatic pseudolymphoma is a rare benign liver mass that is characterized by proliferation of non-neoplastic lymphocytes extranodally. To the best of our knowledge, only 46 cases have been reported in the English literature. We described the case of a 75-year-old woman with hepatic pseudolymphoma mimicking a hypervascular tumor. After the histological confirmation of the rectal neuroendocrine tumor, CT scan revealed a 1.0 cm-sized, poorly-defined and low-density nodule in the liver. On MRI, the hepatic nodule showed an arterial enhancement and a low-signal intensity on the hepatobiliary phase. On diffusion-weighted imaging, the hepatic nodule showed a high signal intensity on a high b-value. On fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT, it revealed a high standardized uptake value nodule. The US showed the hypoechoic nodule and the US-guided biopsy confirmed the hepatic pseudolymphoma.

Osteochondromadevelop most commonly at distal femur, proximal humerus and proximal tibia, but the rib osteochondroma was reported less commonly. In this report, scapular snapping syndrome complicated by adventitious bursa and soft tissue pseudotumor surrounding the osteochondroma of the $6^{th}$ rib body was treated successfully by surgical excision of them. We report this rare case with reviewing the relevant literature.

Posttraumatic psoudoaneurysrns of the subclavian artery are very rare. A 49-year-old woman who had been involved in a car accident ten years before presentation was initially diagnosed with a mediastinal tumor at a local clinic. Exploratory thoracotomy was performed for evaluation and treatment. During the operation, a hematoma was evacuated, and primary repair was undertaken to stop massive bleeding. Computed tomography angiography revealed a pseudoaneurysm of the left subclavian artery. The patient was treated with aneurysmectomy and end-to-end anastomosis. The postoperative course was uneventful.

An 81 year-old male patient presented with rapid enlargement of left lateral neck mass, diagnosed two months earlier as cervical nontuberculous mycobacterial lymphadenitis. Abscess formation and impending rupture related to aggravation of nontuberculous mycobacterial lymphadenitis was highly suspected. Unexpectedly, blood flow was detected by Doppler ultrasonography, which indicated possible vascular mass. Computed tomography demonstrated a $6.0cm{\times}4.0cm$ sized enhancing mass consistent with pseudoaneurysm of internal carotid artery. The patient underwent pseudoaneurysmectomy. Surgical drainage without adequate evaluation might have led to potentially life-threatening condition. We describe this rare case with importance of imaging screening in a neck mass.

Inflammatory pseudotumor is a infrequent, benign tumor that affects at all ages and involves the lung, gastrointestinal tract, and salivary gland. They are the most common, isolated, primary lesion of the lung in children, and usually present as circumscribed, peripheral, parenchymal tumors or endobronchial tumors, which may be usually static or increase slowly in size without causing symptoms. Surgical excision is the treatment of choice because of the location and benign nature of this lesion. The prognosis after resection is excellent. Other therapeutic modalities include radiation and steroid therapy. We experienced two cases of inflammatory pseudotumor of the lung parenchyme and endobronchus. We report these cases with a review of literatures.

A relatively rare and puzzling tumor of the testicular tunic is reported. The tumor, so called a fibrous pseudotumor of testicular tunics, is presented because of the clinical dilemma this rare entity causes urologists and pathologists. This report demonstrates the necessity for familiarity with testicular pseudotumors in order to avoid an unnecessary orchiectomy.

Pseudomyxoma peritonei (PMP) is a rare clinical syndrome characterized by profuse jelatinous materials in the abdominal cavity and pelvis with mucinous implants on the peritoneal surface. There are some studies for serum tumor markers, including carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 125 (CA125), to assess the risk of recurrence following cytoreductive surgery and intraperitoneal chemotherapy. However, rare cases were reported about recurrence with increasing serum CEA levels. Herein, we report a case of recurrence of PMP according to serially elevated serum CEA.

Schwannoma is a benign well-encapsulated tumors arising from the sheath of Schwann cell of the peripheral motors, sensory, and cranial nerves, but not from the optic and olfactory nerves. Since it is relatively common in the head and neck region, it should be included in the differential diagnosis of head and neck tumor. However, reports of laryngeal involvement have rarely appeared in the literature. We have experienced a 50-year old woman and 39-year old woman with history of progressive voice change. We recognized a benign mass at the false cord area with the telelaryngoscope and CT. The tumors were successfully removed by transoral CO2 laser resection without tracheotomy.
