Pleomorphic adenoma of the nasal septum

Despite the common occurrence of pleomorphic adenoma of major salivary glands, intranasal pleomorphic adenoma are rare. We present a ease of pleomorphic adenoma of the nasal septum along with a brief review of literature. The histological nature of this lesion in comparison to other salivary gland tumours and the importance of an accurate diagnosis has been stressed.

儿童跟骨动脉瘤样骨囊肿:病例报告及文献分析

[目的]跟骨动脉瘤样骨囊肿是一种少见病，本文报告了1例儿童跟骨动脉瘤样骨囊肿患者。[方法]本文结合文献回顾性分析了跟骨动脉瘤样骨囊肿患儿的临床、影像学及组织病理学表现。[结果]肿物累及右侧跟骨，经肿物刮除术和植骨术后恢复良好。组织病理学检查确诊为右侧跟骨动脉瘤样骨囊肿。随访2年无复发。[结论]跟骨动脉瘤样骨囊肿是一种少见病，对于单纯的动脉瘤样骨囊肿，肿物刮除术和植骨术是有效的治疗方法。     

33例肝占位性病变MRI误诊的分析

我院１９８８年以来４０００余例腹部ＭＲＩ中，发现肝占位性病变误诊３３例。所用机型为美国Ｄｉｓｏｎｉｃｓ公司０．５Ｔ超导ＭＲＩ，自旋回波序列（ＳＥ序列）、常规Ｔ１加权（Ｔ１ＷＩ）、质子加权（ＰＤＷＩ）、Ｔ２加权（Ｔ２ＷＩ），覆盖全肝。其中，ＰＨＣ误诊为ＭＨＣ５例、ＭＨＣ误诊为ＰＨＣ６例、ＰＨＣ误为ＨＨＥ５例、ＭＨＣ误诊为ＨＨＥ２例、ＨＨＥ误诊为ＰＨＣ６例、肝硬化结节误诊为ＰＨＣ２例、炎性假瘤误诊为ＰＨＣ３例、肝结核误诊为ＰＨＣ１例、ＨＣＹ误诊为ＨＨＥ３例。本文从病变的影像学特征和扫描技术方面详细探讨了误诊的原因和鉴别诊断要点。     

支气管囊肿的X线诊断及其组织胚胎学基础

本文分析１６例支气管囊肿的胸部平片、体层、支气管造影、ＣＴ及其手术病理资料，探讨术前影像学误诊的组织胚胎学基础，尤其是肺外支气囊肿。指出胸瓿平片和体层依然是这类疾病的首选方法，ＣＴ或ＭＲＩ是必要的补充，特别是对囊肿内容物和囊壁的组织结构的分析是同其他疾患鉴别的关键，临床表现和形态学表现没有明显的特异性。     

A case of periodic sweating associated with a subarachnoid cyst and multifocal dystonia

Acase of periodic sweating with multifocal dystonia is reported in a 60-year-old woman. At the age of 48 years, she presented with involuntary twisting of the lower face on the right. Six months later she noticed similar movements in the head and right arm. Four years later she began having attacks of generalized sweating over the whole face, anterior region of the trunk and both arms. The attacks occurred hourly each and every day. They lasted for about 10 min and were followed by voluntary urinary voiding. The biochemical and laboratory investigations showed no abnormalities except for the luteinizing hormone and follicle-stimulating hormone values that were below normal. The computerized tomography and magnetic resonance imaging scans revealed a suprasellar cyst. Clonazepam was introduced with partial improvement of the dystonic movements but not of the sweating attacks. The patient refused surgery. Acetazolamide was added and reduced the sweating attacks. We speculate that the periodic sweating may be related to cerebrospinal fluid production and cyst enlargement, hence the ability of acetazoleamide, which reduces cerebrospinal fluid production, to reduce attacks.     

Stereotactic endoscopic treatment of colloid cysts of the third ventricle

Summary In order to avoid invasive procedures (transfrontal, transcallosal) in the surgical treatment of colloid cysts the stereotactic aspiration technique was introduced by Bosch, RÄhn and Backlund in 1978. The viscosity of the intracystic colloid and the displacement of the cyst away from the aspiration needle are possible reasons for unsuccessful aspiration. GT-guided stereotactic endoscopic technique gives the opportunity to fenestrate the cyst wall under direct visual control.After CT-guided stereotactic puncture of the right lateral ventricle with the foramen of Monro as target a steerable endoscope is introduced and the foramen of Monro is passed. The wall of the cyst is fenestrated and coagulated by means of monopolar (or laser) coagulation.Using this technique we have treated four patients with colloid cysts. Immediately postoperatively all of them were relieved of their complaints and have been symptomfree for a mean follow up period of twelve months. Studies of cerebrospinal fluid flow patterns, performed prior to and every six months after the endoscopic intervention, confirmed a remarkable reduction of foraminal obstruction.     

Primary leiomyosarcoma of the thyroid gland

Primary leiomyosarcoma of the thyroid gland is extremely rare, and to the best of our knowledge only five well-documented cases have been reported in the world literature. We herein report a 58-year-old female patient with primary leiomyosarcoma of the thyroid who was successfully treated by total thyroidectomy with a modified neck dissection. Immunohistochemically, the tumor cells showed positive reactivity to α-smooth muscle actin and vimentin. Radical surgery was thus considered to be essential in the treatment of this rare but rather aggressive malignancy.
