BACKGROUND: Radionecrosis of the larynx is uncommon and usually occurs among laryngeal cancer patients who have undergone radiotherapy. Patients with severe radionecrosis were reviewed for analysis and discussion of symptoms and managements.

背景： 放射性喉部坏死并不常见，通常认为只发生在接受放射治疗而未接受全喉切除的喉癌或下咽癌患者身上。

Objective To investigate the differential diagnosis value of 1H magnetic resonance spectroscopy (1H-MRS) and (superscript 99m)Tc-methoxy isobutyl isonitrile single photon emission computed tomography on postradiotherapy relapse and radionecrosis. Methods 1H-MRS and SPECT were performed in all 35 cases.

目的 探讨质子磁共振波谱(1H-MRS)和99mTc-甲氧基异丁基异腈单光子发射计算机断层显像对脑肿瘤患者放疗后复发与放射性坏死的鉴别诊断作用。

The median weight loss was 18 lb (range, 0–47 lb). Eight patients (16%) deeloped aspiration pneumonia during and after treatment. Fie patients (10%) died of aspiration (2 during and 3 post treatment). Four patients (8%) deeloped esophageal strictures requiring repeated dilatations post treatment. Two patients had radionecrosis (1 soft tissue and 1 bone) requiring hyperbaric oxygen. Eighteen patients (37%) had prolonged tube feedings (N3 months) after treatments because of seere dysphagia or aspiration.

体重减轻中值为18磅（范围，0-47磅）。8例患者（16％）在治疗期间和治疗后发生吸入性肺炎。5例患者(10%)死于误吸（2例在治疗期间，3例在治疗后）。4例患者(8%)治疗后发生食道狭窄需要反复食道扩张。2例患者有放射性坏死（1例为软组织，1例为骨）需要高压养治疗。8例患者(37%)治疗后因为严重的吞咽困难和误吸而持续管饲。

Compared with the pathological examinations of the 21 cases, the accuracy of distinguishing recurrent tumor was 61.9% and 90.5% for mri and for pet respectively. conclusion 18f-fdg pet is more sensitive and accurate than mri in differentiating radionecrosis and recurrence of gliomas after interstitial brachytherapy.

18f-fdg pet在胶质瘤间质内放疗后区分放射性坏死与肿瘤复发方面较mri更敏感而准确。
