三叉神经痛(TN)的特征是沿三叉神经分布反复发作的阵发性短暂的电击样疼痛。基于根本原因,目前的分类系统将TN分类为特发性,古典和次要TN。该手稿提供了在临床上看到的具有继发于颅内病变的TN特征的患者的病例报告。
一位39岁的女性到诊所就诊,有15个月的严重病史,间歇性,影响左下牙的短期疼痛发作,下巴,鼻子和颞区。患者在体格检查过程中报告了熟悉的休克样疼痛,轻轻触摸鼻子的左侧皮肤。其余临床检查无显著性。大脑的磁共振成像(MRI)显示在左桥小脑角水平处有约20mm宽的病变。在后续测试之后,病灶被诊断为脑膜瘤,患者接受了立体定向放射治疗。
■在高达10%的TN病例中,根本原因可能是脑瘤。虽然持续疼痛,感觉或运动神经功能障碍,步态障碍和其他神经系统症状可能同时存在,为颅内病理学升起红旗,患者通常仅表现为脑瘤的预示症状。由于这个原因,作为诊断工作的一部分,所有怀疑患有TN的患者都必须接受脑部MRI检查.
UNASSIGNED: Trigeminal neuralgia (TN) is characterised by recurrent paroxysmal brief episodes of electric shock-like pain along the trigeminal nerve distribution. Based on the underlying cause, the current classification systems have classified TN into idiopathic, classical and secondary TN. This manuscript presents a
case report of a patient seen in the clinic with features of TN secondary to an intracranial lesion.
UNASSIGNED: A 39-year-old female presented to the clinic with a 15-month history of severe, intermittent, short-lasting episodes of pain affecting the left lower teeth, jaw, nose and temporal region. The patient reported familiar shock-like pain during the physical examination when the skin of the left ala of the nose was lightly touched. The rest of the clinical examination was non-significant. The magnetic resonance imaging (MRI) of the brain showed an approximately 20 mm wide lesion at the level of the left cerebellopontine angle. After subsequent tests, the lesion was diagnosed as meningioma, and the patient was treated with stereotactic radiation therapy.
UNASSIGNED: In up to 10% of TN cases, the underlying cause can be due to a brain tumour. Although persistent pain, sensory or motor nerve dysfunction, gait disturbances and other neurological signs may concurrently exist, raising a red flag for intracranial pathology, patients often present with pain alone as the heralding symptom of a brain tumour. Due to this, it is imperative that all patients suspected of having TN undergo an MRI of the brain as part of the diagnostic work-up.
