Purpose: In this study, contrubitions of computed tomography (CT) and magnetic resonance imaging (MRI) were researched in the diagnosis of benign paranasal sinüs (PNS) lesions. Materials and methods: According to the clinical findings, between January 2001 – February 2004, 30 cases have been studied who were thought to have benign lesions belonging to nasal cavity, PNS or neighboring structures. CT and MRI studies are made to the all case. Inner structure characteristics, locations and radiological apperarances coursing pathological diagnosis of lesions in CT and MRI have been assessed. Results: The histopathological diagnoses of lesions were mucocele (8), odontogenic cysts (4), fibrous dysplasia (3), inverted papilloma (2), hemangioma (2), menengioma (2), schwannoma, osteoma, osteochondroma, paget disease, ameloblastom, giant cell tumor, central giant cell granuloma. Whwn assessed according to pathological results, sensitivity of CT and MRI were found to be 86.6% and 83.3% respectively. In 3 cases showing radiological malign feature (1 giant cell tumor, 2 inverted papillomas) the correct diagnosis was made histopathologically. Canclusion: CT is an effective method to show bone expansion and destructions, tumors originated from bone and intratumoral calcifications. MRI offers better the inner structures of cystic lesions, intratumoral hemorhages and differentiation of tumor from inflammation. Therefore, CT and MRI should be used jointly in the evaluation of the PNS lesions.

Neurogenic tumors ocur at all part of the body but most common site is the posterior mediastinum in thorax. In this study, the patients with neurogenic tumor were evaluated clinical and radiological signs in our hospital between January 1999 and December 2003. Of thirty patients were (11 male and 19 female) their range aged from 20 to 70 mean 41.7±11.8. Histological types were 17 (%57) neurofibromas. 7(23%) schwannomas, 4(13%) ganglioneurinomas, 2(7%) malign schwannomas. Twenty-four (80%) of neurogenic tumors were in posterior mediastinum and the others were in different areas in thorax.

Schwannoma is a benign, solitary, and slowly progressive encapsulated tumor originating from the sheath of myelinated nerve fibers. The neoplasm should arise from all the peripheric, spinal or cranial nerves and frequently seen in the head and neck region. A 33 years-old male presented with a 10x10x6 cms giant mass of the right neck. A surgical resection was performed and the histopathologic examination of the mass was reported to be “schwannoma”. Here, a case of giant schwannoma, which is very rare in the literature, and treatment modalities are discussed.

in this manuscript a cervical vagal schwannomo is reported. Von Reckiirzklıausen disease was associated to the schwannoma. The relationship between two entilles is discussed. The imporiance of the vagal schwannoma in the dillerantial diagnosis of the head-neck massed rs impressed and the pertinent literature reviewed.

Aim: Mesenchymal tumors of the gastrointestinal tract other than gastrointestinal stromal tumors are rare and most of them are benign. The aim of this study to reveal the clinical and pathological features of non-gastrointestinal stromal tumor mesenchymal tumors of the gastrointestinal tract.

Materials and Methods: All gastrointestinal endoscopic and surgical resection materials, between 2008-2018, were retrospectively reviewed. Cases diagnosed with mesenchymal tumor other than gastrointestinal stromal tumors were included.

Results: Twenty four lipomas, 14 inflammatory fibroid polyps, six leiomyomas, four lymphangiomas, four hemangiomas, four schwannomas, two neuromas, two malignant melanomas, one leiomyosarcoma, one granular cell tumor and one Kaposi sarcoma were detected. The median ages of the cases were 61 years (29-87), the median tumor size was 1.5 cm (0.2-14). Thirty seven (58.7%) cases were female and 26 (41.3%) were male. They caused nonspecific symptoms. No recurrence or metastasis was detected after excision in benign tumors regardless of the pathological diagnosis.

Conclusion: Non-gastrointestinal stromal tumor mesenchymal tumors of the gastrointestinal tract are mostly small and benign tumors that can be seen at any age and are frequently seen in women. The most common ones are lipomas and inflammatory fibroid polyps. Most gastric tumors cause dyspeptic complaints and intestinal tumors cause abdominal pain, nausea or vomiting, as well as some of the intestinal tumors lead to serious, even fatal clinical situations such as acute and chronic bleeding, obstruction, perforation, volvulus or intussusception. For benign tumors’ treatment, excision is sufficient, they do not exhibit recurrence or metastasis.
