摘要

背景 肌肉疝是一种不常见的疾病,通常发生在四肢;而颌下肌疝则更为罕见。然而,临床医生和放射科医生必须意识到这种可能性。肌内静脉畸形(IMVM)也不常见,主要发生在头部、颈部和四肢。同时出现这两种病症的情况非常罕见,据我们所知,以前还从未有报道称肌肉内静脉畸形会发生在咀嚼肌上。由于其罕见性、表现模糊、临床诊断不准确,因此需要进行放射学评估,以避免不当的手术方案。病例报告 一名 12 岁男孩的左侧面颊肿胀病灶由来已久,咬牙时肿胀加剧。侧位 X 光片显示左下颌区域有圆形钙化。超声波检查显示,左侧咀嚼肌肿大,有局灶性异质结构和两个圆形钙化灶。在咬紧牙关时,超声波检查发现局灶性肌肉疝气穿过左侧咀嚼肌面神经,休息后症状减轻。患者被诊断为左侧咀嚼肌疝与IMVM并存。手术切除了IMVM,并修补了疝气缺损。组织病理学证实了诊断结果,短期随访后患者无术后并发症,已康复出院。结论:尽管咀嚼肌疝和咀嚼肌瘤非常罕见,但在任何咀嚼肌病变的鉴别诊断中都应考虑到这两种病变,尤其是儿童。我们报告了一起非常罕见的同时存在这两种病变的病例。综合临床检查、X光检查和超声波检查可做出全面诊断。

Intramuscular Venous Malformation Associated with Muscle Herniation of the Left Masseter Muscle in a 12-Year-Old Boy.

BACKGROUND Muscle hernias are an uncommon condition typically found in the extremities; masseter muscle hernia is even rarer. However, it is important for clinicians and radiologists to be aware of this possibility. Intramuscular venous malformation (IMVM) is also uncommon and mostly found in the head, neck, and extremities. The simultaneous presence of both conditions is extraordinary uncommon, and, to our knowledge, this has not been reported before in the masseter muscle. Due to their rarity, vague presentation, and inaccurate clinical diagnosis, radiological evaluation is needed to avoid inappropriate surgical planning. CASE REPORT A 12-year-old boy had a long-standing focal left cheek swelling exacerbated by teeth clenching. Lateral X-ray revealed a round calcification over the left mandibular region. Ultrasonography indicated a bulky left masseter muscle with focal heterogeneous structure and 2 rounded calcified foci. During teeth clenching, ultrasonography detected focal muscular herniation through the left masseter muscle facia that reduced with rest. The patient was diagnosed with left masseteric muscle hernia coexistent with IMVM. Surgical excision of the IMVM was performed, and the hernia defect was repaired. Histopathology confirmed the diagnosis, and the patient was discharged without postoperative complications on short-term follow-up. CONCLUSIONS Despite their rarity, masseter hernias and IMVMs should be considered in the differential diagnosis of any masseter lesion, especially in children. We reported a very rare coexistence of both pathologies. Comprehensive diagnosis can be achieved through a combination of clinical examination, X-ray, and ultrasound assessments.
