However, ultrasound is operator-dependent, and magnetic resonance imaging is often unavailable or contraindicated, as in patients with metallic foreign bodies. Computed tomography has traditionally not been considered a method of choice for visualizing nerve structures due to its low soft-tissue contrast.</p> <p>This clinical case describes a 35-year-old male with post-traumatic neuropathy of the left sciatic nerve following a shrapnel wound to the thigh. Conservative therapy for &gt;6 months was ineffective. Computed tomography performed to rule out osteomyelitis allowed detailed visualization of the sciatic nerve along its course, revealing scar tissue compressing the nerve in the middle third of the thigh and a metal fragment in its bifurcation zone. Quantitative analysis of nerve tissue density revealed a pattern: the density of the healthy nerve on the contralateral side was in the negative Hounsfield unit range, which is characteristic of normal nerve tissue, whereas the affected nerve had higher values, reaching a maximum in the compression zone. These findings were fully confirmed intraoperatively during microsurgical neurolysis.</p> <p>This case demonstrates that native computed tomography may in some cases serve as an additional imaging method in patients with post-traumatic sciatic neuropathy, especially in clinically challenging situations where magnetic resonance imaging is contraindicated or unavailable.</p></abstract><trans-abstract xml:lang="ru"><p>Диагностика посттравматической невропатии периферических нервов традиционно опирается на комплекс методов: клинический осмотр, электронейромиографию, ультразвуковое исследование и магнитно-резонансную томографию. Однако ультразвуковое исследование обладает существенной оператор-зависимостью, а магнитно-резонансная томография часто малодоступна или противопоказана, например пациентам с металлическими инородными телами. Компьютерную томографию не считают методом выбора для визуализации нервных структур, что обусловлено относительно низкой контрастностью мягких тканей.</p> <p>В данном клиническом наблюдении представлен 35-летний мужчина с посттравматической невропатией левого седалищного нерва после осколочного ранения бедра. Консервативная терапия в течение шести месяцев не принесла эффекта. Компьютерная томография, выполненная для исключения остеомиелита, позволила детально визуализировать седалищный нерв на протяжении, выявив рубцовый тяж, сдавливающий нерв в средней трети бедра, и металлический осколок в зоне его бифуркации. Количественный анализ плотности ткани нерва выявил закономерность: плотность здорового нерва на противоположной стороне была в отрицательном диапазоне единиц Хаунсфилда, что характерно для нормальной нервной ткани, тогда как поражённый нерв имел более высокие значения, достигавшие максимума в зоне компрессии. Эти данные полностью подтверждены интраоперационно во время микрохирургического невролиза.</p> <p>Настоящее наблюдение демонстрирует, что нативная компьютерная томография в некоторых случаях может служить дополнительным методом визуализации у пациентов с посттравматической невропатией седалищного нерва, особенно в клинически сложных ситуациях, когда проведение магнитно-резонансной томографии противопоказано или недоступно.</p></trans-abstract><trans-abstract xml:lang="zh"><p>周围神经创伤后病变的传统诊断依赖于多种方法的结合：临床检查、肌电图、超声检查和磁共振成像。然而超声检查具有显著的操作者依赖性，而磁共振成像通常难以获取或存在禁忌症，例如体内有金属异物的患者。计算机断层扫描不被视为神经结构可视化的首选方法，这是由于软组织对比度相对较低所致。</p> <p>本临床观察展示了一名35岁男性，因腿部弹片伤后出现左坐骨神经创伤后病变。六个月的保守治疗未见效果。为排除骨髓炎而进行的计算机断层扫描，能够详细可视化坐骨神经全程，发现大腿中三分之一处有瘢痕束压迫神经，并在其分叉区域存在金属碎片。神经组织密度的定量分析揭示了一个规律：健康侧神经的密度在亨斯菲尔德单位负值范围内，这是正常神经组织的特征，而受损神经则具有更高密度值，在受压区域达到最大值。这些数据在显微外科神经松解术中得到术中完全证实。</p> <p>本观察表明，在某些情况下，平扫计算机断层扫描可作为坐骨神经创伤后病变患者，特别是在临床复杂情况下（当进行磁共振成像存在禁忌或无法进行时）的补充可视化方法。</p></trans-abstract><kwd-group xml:lang="en"><kwd>sciatic nerve</kwd><kwd>post-traumatic neuropathy</kwd><kwd>neuroimaging</kwd><kwd>computed tomography</kwd><kwd>case report</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>седалищный нерв</kwd><kwd>посттравматическая невропатия</kwd><kwd>нейровизуализация</kwd><kwd>компьютерная томография</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>坐骨神经</kwd><kwd>创伤后神经病变</kwd><kwd>神经可视化</kwd><kwd>计算机断层扫描</kwd><kwd>临床病例</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Morozova SN, Sinkova VV, Grishina DA, et al.
