OBJECTIVE: To investigate the clinical and pathological features of solitary pterygoid benign lesions, as well as the treatment and outcome of endoscopic surgery. METHOD: We retrospectively analyzed clinical data of 4 patients with pterygoid benign lesions in our department. High resolution CT and enhanced MRI were performed before the operations, then endoscopic surgeries were carried out under the circumstance of general anesthesia. After a follow-up in 12 months to 48 months, nasal endoscopy and MRI examination were performed. Therefore we are able to understand the situation of operations and postoperative recurrences, and to inquire about the changes of symptoms and the relief of symptoms before and after surgery. RESULT: From the Pathological diagnosis, it showed 2 cases of cystic lesions, 1 case of spindle cell lipoma, 1 case of inflammatory lesion. Postoperative follow up showed scar formation, smooth surface, no recurrence, and no new symptom. Nasal obstruction is relieved after the surgery, and no changes in the sympotoms of headache were observed. CONCLUSION The combination of high resolution CT with enhanced MRI isimportant for ascertaining the location, extent and nature of the pterygoid lesions. Endoscopic surgery is a minimally invasive, safe, and effective method for the treatment of solitary pterygoid benign lesions.

Lipomas are common benign tumors of mature adipose tissue, enclosed by thin fibrous capsules. They can occur on any part of the body; however, peritoneal lipoma is extremely rare. We encountered a case of a 75-year-old man presenting with intermittent abdominal pain, who had undergone right hemicolectomy due to colon cancer. Abdominal computerized tomography showed a well-defined heterogenous fatty mass measuring 4.5x3.5 cm in size, suggesting fat necrosis located in the abdominal wall. Laparotomy showed a very large soft mass of peritoneum. Pathologically, the tumor was diagnosed as lipoma containing fat necrosis located in parietal peritoneum not fixed to any organs, but with small bowel adhesion. Due to its rare etiologic origin and obscure cause of development, we report on a case of lipoma of parietal peritoneum causing abdominal pain.

OBJECTIVE: To discuss the clinical characteristics, imaging findings, surgical treatment and effectiveness of faciocervical lipomas in children. METHOD: Twenty children with lipomas who were performed surgical resection under the tracheal intubation anesthesia, of which 3 cases located in face and 17 cases located in neck were retrospectively analyzed. Computed tomography (CT) was used in 8 cases and magnetic resonance imaging (MRI) in 6 cases for differential diagnosis. CT and MRI were used to diagnose 6 patients pre-operatively. RESULT: The image of computed tomography (CT) revealed that 15 cases showed oval and flat circular area and 5 cases showed lobulated lesion. The CT value was negative typically. The signal was inhomogeneous in MRI. The patients' magnetic resonance imaging (MRI) presented a high signal intensity on T1 and T2WI. The hyperintense signal can be suppressed in fat-suppression T2WI sequence. The hypointense of tumor signals fell in tandem surrounding adipose tissue. All the patients got satisfied curative effect after operation. There were no complications such as trachyphonia, bucking and dyspnea. Following up for 6 months to 2 years,no recurrence case occurred. CONCLUSION Lipomas generally occur in adult patients, quite rare in children. Imaging examination is helpful in the differential diagnosis of lipoma. Surgical resection is the only effective treatment for lipomas at present.

Retropharyngeal lipomas are rare tumours that are usually asymptomatic until they reach a large size. The definitive treatment is surgical excision. Since the tumours are typically large at the time of presentation, extensive surgery for complete clearance of the lipoma from the retropharyngeal and parapharyngeal regions is to be expected. Transoral excision is typically indicated for small retropharyngeal tumours, as this approach does not give good access to the parapharyngeal area laterally. Herein, we present the case of a patient who underwent transoral excision of a huge retropharyngeal lipoma, which extended into the right parapharyngeal space. The surgical technique used and the insights gained are described in this report. Even with parapharyngeal extension, transoral resection of a huge retropharyngeal lipoma can be performed. More invasive surgery, which may involve a neck incision, mandibulotomy or pharyngotomy, is not necessary. While huge retropharyngeal lipomas are usually symptomatic and require surgical intervention, transoral resection can be adequate and safe for treatment.
