异位胰腺多发生在消化道,肝脏异位胰腺临床非常罕见。笔者报道了1例行18F-FDG PET/CT检查且经手术病理结果证实的肝脏异位胰腺病例,其影像学特征主要表现为十二指肠肿块并伴有18F-FDG异常摄取,考虑为与肝脏异位胰腺相关的炎性病灶表现。笔者拟通过对该病例进行分析并对相关文献进行复习,以加深对肝脏异位胰腺影像学特征的认识。     

Peutz-Jeghers综合征的临床及影像学分析

Peutz-Jeghers综合征即黑斑息肉病,是一种临床少见的常染色体显性遗传性疾病,以皮肤黏膜黑斑和消化道多发息肉为特征.国外文献报道较多,而国内文献报道相对较少[1～9].为进一步提高对此少见病的认识水平,本文结合7例病例资料和文献复习,从临床表现、影像学和病理学方面进行分析.     

同侧卵巢黏液性交界性肿瘤合并成熟性囊性畸胎瘤一例并文献复习

笔者报道了1例同侧卵巢发生黏液性交界性肿瘤（MBT）合并成熟性囊性畸胎瘤（MCT）的病例,从临床症状、实验室检查、影像学表现及病理诊断等方面综合分析了其特点,并通过文献复习总结了该病的影像学表现。MBT和MCT均为卵巢的常见肿瘤,但两种不同性质的肿瘤并存于同侧卵巢非常罕见,其临床表现无特异性,影像学检查若在同一肿块中发现两种肿瘤类型的典型影像学表现,且不能用一种肿瘤解释时,应该考虑同时存在另一种肿瘤的可能。     

腹茧症影像学诊断一例

腹茧症（abdominal cocoon)是临床外科非常罕见的腹部疾病，其临床病理特征是小肠部分或全部被一层灰白色、致密且质地坚硬的纤维结缔组织膜包裹，又称特发性硬化性腹膜炎(idiopathie selerosing peritonitis)。由于发病原因不明确，临床表现缺乏特异性，因此术前常不能及时诊断和治疗。迄今国内外文献报道仅57例，国内文献报道仅10余例。影像学诊断国内外文献描述甚少，笔者遇到腹茧症状1例并经手术证实，现报告如下。     

脾脏窦岸细胞血管瘤的CT诊断及文献回顾

脾脏窦岸细胞血管瘤(littoral cell angioma, LCA)是一种具有特征性免疫组化特点的血管源性肿瘤,由Falk于1991年首次提出[1].由于有关LCA的文献报道较少,临床、影像、病理科医生对该病的认识尚不足,常常导致误诊.因此,本文报道在本院检查、治疗并经术后病理确诊的2例LCA病例资料,结合相关文献讨论该病的临床、病理、尤其是影像学特征.     

多形性胶质母细胞瘤伴发胶质肉瘤1例并文献复习

<正>胶质肉瘤是一种较罕见的中枢系统肿瘤,通常被认为是胶质母细胞瘤的变种,具有神经胶质和间质双向分化的特征。其胶质成分与胶质母细胞瘤非常相似,间质成分多来源于成纤维细胞,因此最常见的类型类似于纤维肉瘤或所谓的恶性纤维组织细胞[1]。现报道多形性胶质母细胞瘤伴发胶质肉瘤1例并复习文献,对其临床表现、术中所见、影像学特征及病理结果进行分析,旨在提高对其认识。

Imaging features of granulosa cell tumors of the ovary: about three cases

Granulosa cell tumors of the ovary are rare, and included in the sex cord-stromal tumor category. They have a low malignancy potential and generally have a good prognosis. They are the most frequent hormone-secreting tumors of the ovary and may lead to suggestive clinical symptoms. Some biological markers (serum inhibin B and AMH) may be helpful for diagnosis, though their sensitivity is not perfect. Preoperative imaging diagnosis remains challenging due to the wide variability in morphology and lack of epidemiological data in the imaging literature (small patient populations). From a review of the clinical and MR imaging features of three cases of granulosa cell tumor of the adult and a review of the literature, we will describe a few imaging features that may suggest the correct diagnosis.     

Biomass Fuel Exposure and Lungs: Unraveling the Imaging Conundrum

Prolonged exposure to biomass fuel smoke is a proven irritant, known to aggravate chronic lung diseases. Of the myriad spectrum of thoracic manifestations associated with inhalation of biomass fuel smoke, bronchial anthracofibrosis is a recently described entity characterized by bronchial narrowing and visible anthracotic pigmentation on bronchoscopy. Common imaging features include bronchostenosis, peribronchial soft tissue with or without calcification along with peribronchial lymph nodes. Its close similarity to endobronchial tuberculosis and bronchogenic carcinoma in clinical presentation and imaging poses a diagnostic challenge and hence underlines the importance of knowledge about this entity. This review aims to summarize the key imaging features of bronchial anthracofibrosis while also briefly discussing the spectrum of thoracic manifestations including distinct entities associated with biomass fuel smoke exposure.     

胸椎孤立性浆细胞瘤1例及文献复习

目的探讨胸椎孤立性浆细胞瘤(SPB)的临床表现、影像特征及鉴别诊断。方法分析1例脊柱SPB病人的CT及MRI表现,并复习相关文献。结果 CT示T10椎体呈楔形,轻度膨胀性、溶骨性骨质破坏,边缘骨硬化,内部见残存骨嵴,未见典型"微脑征"。瘤体均质,未见钙化及肿瘤骨。MRI平扫示病变于T1WI呈低信号,T2WI呈稍高信号,T2WI脂肪抑制序列呈高信号,MRI增强示瘤体呈均匀强化,未见椎旁肿块及脓疡,相邻椎间盘信号无异常。手术病理提示浆细胞来源肿瘤,结合ECT及本周蛋白、血钙及肌酸水平,临床诊断为SPB。结论 SPB好发于椎体前部,溶骨性破坏,瘤体均质,常伴有骨嵴及硬化边。"微脑征"有助于诊断,但敏感性较低。SPB的确诊有赖于影像检查、临床实验室及病理结果的综合分析。     

Thoracic epithelioid hemangioendothelioma: imaging and pathologic features

The purpose of this article is to review the imaging features of thoracic epithelioid hemangioendotheliomas with pathologic correlation. The thoracic manifestation of epithelioid hemangioendotheliomas is one of three different CT patterns: multiple pulmonary nodules, multiple pulmonary reticulonodular opacities, or diffuse infiltrative pleural thickening. Without any evidence of histological malignancy, malignant features (multiplicity of pulmonary nodules, hepatic or bone involvement, lymphangitic tumor spread, and infiltrative pleural masses) are characteristic of these infrequent tumors.     

Chronic inflammatory pseudotumor arising in the hepatobiliary-pancreatic system: progressive multisystemic organ involvement in four patients.

OBJECTIVE: Inflammatory pseudotumor is a benign process that can involve most organ systems. The purpose of this report was to evaluate the imaging features of multifocal chronic inflammatory pseudotumor in four patients who presented with clinical, radiographic, and biopsy evidence of pancreatic or biliary malignancy. CONCLUSION: To our knowledge, this is the first report in the radiology literature describing the imaging features of progressive multifocal inflammatory pseudotumor originating from a primary pancreatic or biliary focus. Even on retrospective review, no distinguishing imaging features were identified that could discriminate benign from malignant disease. These findings emphasize the importance of histopathologic analysis in the diagnosis of malignancy, particularly in patients with previously diagnosed inflammatory pseudotumor.
