Sonographic appearance of focal fatty infiltration of the pancreas

We report the sonographic, CT, and MRI findings in a case of focal fatty infiltration of the pancreas. Sonography revealed an echogenic mass in pancreas head. On CT, the mass was hypodense. The mass showed same signal intensity to the surrounding normal pancreas on in‐phase T1‐weighted MR images and a loss of signal intensity on opposed‐phase MR images. © 2009 Wiley Periodicals, Inc.

Facial reanimation surgery utilizing the Mitek anchor system: A case report

A flaccid hemi-face is frequently the most noticeable and cosmetically unacceptable consequence of facial nerve palsy, whether due to trauma, Bell's palsy or other etiologies. A variety of face-lift and reanimation techniques have been utilized in the past, but with time, these frequently require further surgery. We describe the use of Mitek (Norwood, MA) suture anchors for cheek resuspension in a patient with facial palsy. This system is composed of a drill guide, drill, inserter, and anchor. Although the titanium alloy anchors come in multiple sizes, the Mini GII Anchor is typically most appropriate for use in facial procedures. The actual size of the Mini GII Anchor is 1.8 mm in diameter and 5.4 mm in length. Two small arched prongs extend from the body of the anchor, and an eyelet at the superior surface is used for suture placement. When placed into a pre-drilled hole with the insertion tool, the prongs extend, effectively fixing the anchor in place. The drill guide protects adjacent soft tissues during the drilling process and allows drilling to a predetermined fixed depth. Sutures attached to the anchor may then be used for soft tissue fixation to bone.     

Spinal hamartoma associated with spinal dysraphism

Objects The aims of the study were (1) to review the pathological findings of spinal lipomatous masses associated with congenital spinal dysraphism and (2) to discuss the pathological diagnosis.Methods The pathological records of 47 patients at our institution were reviewed, and three illustrative cases were presented.Conclusion Spinal tumorous lesions associated with spinal dysraphism have been traditionally described as lipoma since they are composed mostly of fatty tissue. However, they are different from lipomas arising in other part of the body in that they often contain various tissues of ecto- and mesodermal origin. In our study, we detected such heterotopic components in 24 out of 47 cases. Although they are also similar to teratoma, it is generally accepted that they are malformative lesions which lack neoplastic potential. We therefore should diagnose them as hamartoma rather than lipoma or teratoma.     

胫、股骨内压与膝关节疼痛关系的研究和治疗方法探讨

作者对膝关节痛和休息痛的病人21例测量了股、胫骨内压和关节镜检查,其均值股骨髁0.143±0.011kpa,16例(76.19％)超过对照组0.130kpa(P<0.01);胫骨髁0.180±0.022kpa,18例(85.7％),超过对照组0.105kpa。同时测量膝关节腔内压21例,均值为0.135±0.035kpa,18例(85.7％),高于对照组0.120kpa。认为骨内压增高是引起膝关节痛的原因之一。     

Spindle cell lipoma—a pseudoangiomatous variant

Five cases of an unusual pseudoangiomatous variant of spindle cell lipoma are presented. In keeping with more typical cases, these lesions occurred principally in the shoulder and neck regions of adult males. The lesions all had the features of typical spindle cell lipoma but, in addition, exhibited irregular and branching spaces with villiform connective tissue projections, giving a striking angiomatoid appearance. Although the pathogenesis is uncertain, this unusual histological pattern seems to be the result of myxoid degeneration and may lead to a mistaken diagnosis of a true vascular tumour or other non-lipomatous spindle cell lesion.     

Island of salivary gland in adipose tissue: a report of three cases

Although uncommon, many variants of lipomatous lesions in or around salivary glands have been reported in the literature. We report a series of three such cases in the minor salivary gland region. The first case (oral floor) is a well-circumscribed lipocytic lesion admixed with glandular components (mucous acini, serous demilunes and ducts). The second case (alveolar mucosa) is a diffuse lipomatous proliferation with entrapped salivary glandular elements, muscles and blood vessels. The third case (palate) is similar to the first case but the gland is located at the periphery of the lesion. The purpose of the article was to report these three lesions and discuss in relation to other pertaining lipomatous lesions (sialolipoma, lipoadenoma, lipomatosis, lipometaplasia in pleomorphic adenoma and infiltrating lipoma).     

Balloon-assisted endoscopic submucosal dissection for treating small intestinal lipomas: Report of two cases

BACKGROUNDMost small intestinal lipomas are treated surgically, and some require repeated surgeries for multiple lipomas. However, application of endoscopic submucosal dissection (ESD) technology in the deep small intestine is rarely reported owing to the special anatomical structure of the small intestine, medical equipment limitations, and the lack of relevant experience among endoscopists.CASE SUMMARYTwo patients with small intestinal lipomas treated at the Air Force Medical Center from November 2015 to September 2019 were selected to undergo balloon-assisted ESD to treat the lipomas and explore the technical feasibility and safety of ESD for treating small intestinal lipomas. The two patients successfully underwent balloon-assisted ESD to treat four small intestinal lipomas, with a complete resection rate of 100% (4/4), without intraoperative or postoperative bleeding, perforation, or other complications. After 3-6 mo of postoperative follow-up, the clinical symptoms caused by the lipomas were significantly relieved or disappeared after treatment.CONCLUSIONBalloon-assisted ESD is a safe and reliable new method for treating deep intestinal lipomas and shows good clinical feasibility.
