U máu trong cơ ở trẻ em: Báo cáo ca bệnh hiếm gặp

Abstract

Intramuscular hemangioma (IMH) is a benign hemangioma found within skeletal muscle. It is a rare lesion when considering all types of benign hemangiomas. Watson and McCarthy estimated that IMH accounts for only 0.8% of all benign hemangiomas. Many of these lesions are considered congenital tumors that gradually become symptomatic. Although any muscle can be affected, most intramuscular hemangiomas are located in the lower extremities, particularly the thigh muscles, and are extremely rare in the upper extremities. Chronic pain and palpable mass are the most common symptoms. Due to the atypical clinical features of the disease, accurate diagnosis is challenging. We report a case of a 16-month-old female presenting with pain and limited mobility of the right hip joint. Diagnostic imaging revealed an irregular bony lesion in the right iliac fossa, with cortical discontinuity and infiltration into the right iliopsoas and gluteus minimus muscles. Histopathological examination of the affected muscle tissue confirmed a capillary type hemangioma. The patient was treated with analgesics in combination with rehabilitation therapy. This approach permitted the patient to achieve proper gait and posture, increase hip joint range of motion, and preserve the range of motion in the right knee and ankle joints.
