软骨粘液样纤维瘤的X线诊断

软骨粘液样纤维瘤是一种少见的骨良性肿瘤，来源于成软骨性的结缔组织，占骨肿瘤1．1％，良性骨肿瘤2．1％（1），1948年Jaffe和Lichtenstein首先报导并命名，国内迄今报导有7篇48例（2－8），西文报告7例，共55例。既往由于对本病认识不足，病理上常误诊为软骨肉瘤，软骨瘤，粘液肉瘤等，X线上常易误诊为巨细胞瘤，骨囊肿，良5性软骨母细胞瘤，软骨瘤，动脉瘤样骨囊肿等。本组7例中，仅有1例术前诊断此病，余皆误诊，本文就国内所报导的病例加上本组病例一样进行讨论。     

Chondromyxoid fibroma of the rib with prominent exophytic configuration

Chondromyxoid fibroma (CMF) of the rib is exceedingly unusual and few detailed image findings have been reported. Plain radiograph, computed tomography (CT), and magnetic resonance (MR) imaging findings and pathological aspects of a case of CMF of the right 2nd rib in a 15-year-old woman are reported, which was difficult to diagnose preoperatively. Though it is challenging to diagnose CMF preoperatively, it is important to be aware that CMF can exhibit atypical prominent exophytic features in unexpected locations such as the ribs.     

Chondromyxoid fibroma of the temporomandibular joint. Apropos of a case report

A 32-year-old woman presented with a chondromyxoid fibroma of the right temporomandibular joint. The tumor is rarely observed but this case emphasizes the need for complete radiological investigation of this joint in patients with clinical symptoms localized to this region.     

小儿心脏纤维瘤病1例

患儿男,3岁。因发热、咳嗽2周入院。查体:T36.7℃,心率169次/min,呼吸54次/min。精神差,呼吸促,口周发绀,双肺呼吸音清,心音低,心尖部及胸骨左缘第三肋间可闻及Ⅲ/6级收缩期杂音,双下肢无浮肿。辅助检查:心电图示窦性心动过速、左心室肥厚。X线胸片示肺纹理稍增粗。超声心动图示:室间隔右室侧探及一略强回声团,向右室流出道膨出,大小约2.2cm×1.8cm,右室流出道内径最窄处7.2 mm。     

Chondromyxoid fibroma of the metacarpal

This report describes a chondromyxoid fibroma which developed in the distal part of the second metacarpal of a 12-year-old girl. The tumor is rare, perhaps the rarest of all bone tumors, and the occurrence in a metacarpal of a young female is extraordinarily uncommon.     

肋骨海绵状血管瘤1例

血管瘤为常见肿瘤,发生于肋骨少见,现报道1例如下。患者,女性,35岁。因外伤后检查发现左侧第7肋骨病变2年就诊。查体胸部无阳性体征。实验室检查无特殊。     

Chondromyxoid fibroma of the sacrum

A 30-year-old man with a 7-month history of mild sacral pain and intermittant left sciatica was found to have an expansile lesion in the sacrum on a plain radiograph. Biopsy confirmed a chondromyxoid fibroma which was removed surgically. A 1-year follow-up showed no recurrence. The case is the fifth to be reported. Plain film and MRI appearances, histology and treatment are described. The previously reported cases are reviewed and the current literature is discussed. Received: 14 September 1998; Revision received: 17 December 1998; Accepted: 18 December 1998     

Chondromyxoid fibroma of the rib mimics a chondrosarcoma on 18F-FDG PET/CT

Chondromyxoid fibroma (CMF) is a rare benign bone tumor of chondroid origin that occurs mostly in the metaphyses of long bones. CMF can occasionally mimic a chondrosarcoma on CT, and the literature on the 18F-FDG PET/CT imaging characteristics of CMF tumors is limited. In the presented case, a large histologically proven CMF chest wall mass was initially misinterpreted as a chondrosarcoma. This case highlights a potential pitfall in the PET/CT evaluation of these rare benign bone tumors.     

Chondromyxoid fibroma of the foot

 Chondromyxoid fibroma is a rare benign cartilaginous tumour seen most frequently around the knee in children and young adults. Up to 17% occur in the foot, where more aggressive appearances have been reported. Four cases of chondromyxoid fibroma in the forefoot are presented, demonstrating the wide range of radiological appearances of this primary tumour. Three of the four tumours recurred, one at 19 years after surgery. These cases illustrate the need for thorough preoperative assessment to ensure complete surgical resection in an attempt to reduce the incidence of local recurrence.
