Воспалительная миофибробластная опухоль (ВМО) – редкая опухоль, характеризующаяся пролиферацией веретенообразных клеток с инфильтрацией воспалительными клетками. ВМО называют также воспалительной псевдоопухолью или псевдосаркоматозной миофибробластической опухолью. Несмотря на редкость (составляет менее 1% всех опухолей мочевого пузыря), мочевой пузырь является наиболее частой локализацией ВМО среди всех органов мочеполового тракта. В публикации мы описываем пациента М., 1 год 7 месяцев, у которого были жалобы на затруднения и боли при мочеиспускании в течение 2 месяцев. После проведённого обследования (УЗИ, микционной цистографии, КТ брюшной полости и малого таза, цистоуретроскопии, МРТ органов малого таза) ребёнку выполнено хирургическое лечение – иссечение (энуклеация) опухоли в пределах здоровых тканей. После гистологического исследования установлен диагноз «Воспалительная миофибробластная опухоль». В течение последних 2 лет ребёнку выполняли УЗИ, КТ, МРТ: признаков рецидива не выявлено, что подтверждается данными литературы о низком уровне рецидивов опухоли после щадящих видов хирургического лечения и отсутствия химиотерапии.

Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm characterized by proliferation of spindle‑shaped cells with prominent inflammatory cell infiltration. IMT is also referred to as an inflammatory pseudotumor or pseudosarcomatous myofibroblastic tumor. Although it accounts for less than 1% of all bladder tumors, the bladder is the most frequent site of IMT within the genitourinary tract. In this report, we present the case of patient M., a 1‑year‑7‑month‑old child with a 2‑month history of dysuria and painful voiding. Following a diagnostic work‑up, including ultrasound, voiding cystography, abdominal and pelvic CT, cystourethroscopy, and pelvic MRI, the child underwent surgical excision (enucleation) of the mass with negative margins. Histopathological examination confirmed the diagnosis of IMT. During 2 years of follow‑up with ultrasound, CT, and MRI, no evidence of local recurrence was detected, which is consistent with published data indicating low recurrence rates after organ‑sparing surgical management without adjuvant chemotherapy.
