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.

Renal inflammatory pseudotumor is a very rare benign condition of unknown etiology characterized by proliferative myofibroblasts, fibroblasts, histiocytes, and plasma cells. In the case we report, the lesion appeared on contrast-enhanced power Doppler US images as a well-defined hypoechoic mass with intratumoral vascularity, and on CT as a low-attenuated mass. Differentiation from malignant renal neoplasms was not possible.

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.

Inflammatory pseudotumor, also known as plasma cell granuloma, is a rare, benign tumor that affects at all ages and frequently involves the lung, gastrointestinal tract, and salivary gland. They are the most common, isolated, primary lesion of the lung in children less than 16 years of age, and usually present as circumscribed, peripheral, parenchymal tumors, which may be static or increase slowly in size without causing symptoms. Surgical excision is the treatment of choice bacause of the location and benign nature of this lesion. The prognosis after resection is excellent. Adjuvant therapeutic modalities include radiation and steroid therapy. Recently, we experienced a case of inflammatory pseudotumor of the lung, the diagnosis of which was made by percutaneous fine needle aspiration cytology examination. We tried steroid and the lesions of the lung was completely resolved. We report this case with a review of literatures.

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.

Spinal intradural cysticercosis is a rare manifestation of neurocysticercosis. We report a unique patient who showed visual symptoms and normal imaging of the brain caused by isolated spinal neurocysticercosis. A 59-year-old male patient was admitted to the emergency unit with a history of severe headache and progressive blurred vision. Brain computed tomographic scanning and magnetic resonance imaging showed normal cerebral anatomy without hydrocephalus. The fundoscopic evaluation by an ophthalmologist showed bilateral papilledema. Perimetry studies revealed visual field defects in both eyes. With the diagnosis of pseudotumor cerebri, a lumbar tap was attempted; however, we could not drain the cerebrospinal fluid in spite of appropriate attempts. Lumbar magnetic resonance imaging revealed multilevel intraspinal lesions that were confirmed histologically to be neurocysticercosis. An intraoperative lumbar puncture revealed an increased opening pressure and cytochemical analysis showed elevated cerebrospinal fluid protein level. The headache resolved immediately after surgery. However, the visual symptoms remained and recovered only marginally despite antihelminthic medications after six months of operation.

Orbital pseudotumor, also known as idiopathic orbital inflammatory syndrome(IOIS), may have protean clinical manifestations. IOIS should be determined with a diagnosis of exclusion, with evaluation directed toward eliminating other causes of orbital disease. Orbital MRI and CT are the important diagnostic tests, but serologic studies are necessary to exclude a systemic causes. Biopsy is usually not performed currently, as the risk of producing damage to vital structures within the orbital outweighs the benefits. Patients with multiple recurrences, or those unresponsive to therapy, should be treated of biopsy sample extraction. Corticosteroids are the mainstay of therapy and administered for several months to ensure remission. Radiotherapy may be used in patients who fail to respond to steroids or who have a rapidly progressive course. We analysed the data of two patients. There were no specific complications related to this treatment. We discussed the radiologic findings, treatment procedures, and other orbital diseases.

Intraorbital hemorrhage is a rare clinical condition caused by orbital trauma, surgery around the orbit, intraorbital vascular abnormalities, and neoplasm. It was reported to occur spontaneously without any known causes and in association with orbital pseudotumor in a very few cases. A 59-year-old, female patient admitted with sudden onset of severe exophthalmos and pain on the left eye. Orbital CT and MR imaging suggested hemorrhage in the upper part of retrobulbar area of the left orbit. Cerebral angiography was taken to rule out any possible vascular abnormalities. On the left carotid cerebral angiography, the run-off of the distal ophthalmic artery was not seen and the engorgement of the supraophthalmic artery was noted. Systemic administration of corticosteroid did not improve the clinical status and craniectomy was done and retrobulbar hematoma was removed, and the clinical symptoms and signs were improved. Authors report a case of spontaneous intraorbital hemorrhage with the clinical features similar to those of orbital pseudotumor, requiring surgical decompression.

Inflammatory pseudotumor (IPT) is a term defining a mass characterized microscopically by a proliferation of bland mesenchymal spindle cells infiltrated by diffuse mixed inflammatory cells with a predominance of plasma cells and lymphocytes. Here, we show the primo vessel-like structure of the primo-vascular system (PVS) in a dog with IPT. A 6-years old male Mongrel dog was diagnosed with an abnormal mass (diameter 5.5 cm, weight 22 g) near left preputial area. The dog was submitted to the surgical detectomy of the mass. During the surgical operation, we observed primo vessel-like material. After fixations, the masses appeared macroscopically as lipoid-like, firm, white to grey masses, measuring $5{\times}8cm$. Histologically, cellular infiltration into the muscular layers was frequently seen. The mesenchymal proliferation remained the main component of the mass and was composed of myofibroblastic-like spindle cells characterized by globular, irregular nuclei containing open chromatin and a prominent nucleolus. On the basis of the histopathologic lesions, the subcutaneous mass was diagnosed as IPT. Also, we detected a primo vessel-like structures in some areas of the IPT tissues. These were observed as novel thread-like structures and bundle of tubular structures. To our knowledge, this report is the first case of primo vessel-like structure in a dog with IPT.

Inflammatory pseudotumor was originally described in the lung, but recently has been recognized to occur in various sites. A 56-year-old female was referred to our department with a painless swelling of the right midfacial area since 3 months ago. Clinical examination showed non-specific intraoral findings, but asymmetric facial appearance and numbness of the right midfacial area. Plain radiographs and CT images showed aggressive destruction and irregular thickening of the right maxillary sinus wall, increased antral opacification, and destruction of the zygomatic arch. A relatively well-defined soft tissue mass occupied the right maxillary sinus, nasal cavity, zygoma, and infraorbital region. The soft tissue mass showed mild enhancement on CT. Radiographically, this lesion presented a rapidly enlarging mass demonstrating aggressive behavior, mimicking a malignant tumor. Histopathologic examinations showed plasma cells and inflammatory cells in variable fibrotic tissues and demonstrated positive reactivity for vimentin. No malignent changes could be found.
