Meningitis is a serious and potentially life-threatening infection of the central nervous system. Cryptococcus neoformans is a rare fungal cause of meningitis that commonly presents with atypical symptoms. Although this infection is most common in immunocompromised patients, it also occurs in immunocompetent patients. This case report describes an atypical presentation of cryptococcal meningitis in a seemingly immunocompetent patient.
A 40-year-old immunocompetent patient with no significant past medical history had visited the emergency department (ED) five times within a span of 30 days reporting dental pain and headache. Throughout each of the visits, no clear symptoms signaling the need for a meningitis workup were observed, as the patient had been afebrile, displayed no nuchal rigidity, and his presenting symptoms subsided within the ED after treatment. A lumbar puncture was performed after emergency medical services brought the patient in for his sixth ED visit, initially for stroke-like symptoms and altered mental status. Spinal fluid was indicative of cryptococcal meningitis.
This case highlights the challenge of identifying cryptococcal meningitis in the ED, particularly in immunocompetent patients who do not display classic meningitis symptoms. It also highlights the importance of keeping a broad differential and carefully ruling out diagnoses when patients return to the ED multiple times for the same complaint.
脑膜炎是一种严重且可能危及生命的中枢神经系统感染。新型隐球菌是脑膜炎的一种罕见真菌病因,通常表现为非典型症状。虽然这种感染在免疫功能低下的患者中最为常见,但也发生在免疫功能正常的患者中。本病例报告描述了一名看似免疫功能正常的患者中新型隐球菌性脑膜炎的非典型表现。
一名40岁免疫功能正常的患者,既往无重大病史,在30天内因牙痛和头痛5次就诊于急诊科(ED)。在每次就诊期间,均未观察到提示需要进行脑膜炎检查的明确症状,因为该患者无发热,无颈项强直,且其就诊症状在急诊科治疗后缓解。在紧急医疗服务将该患者第六次送往急诊科时,最初是因类似中风的症状和精神状态改变,进行了腰椎穿刺。脑脊液提示新型隐球菌性脑膜炎。
本病例凸显了在急诊科识别新型隐球菌性脑膜炎的挑战,尤其是在未表现出典型脑膜炎症状的免疫功能正常患者中。它还强调了在患者因相同主诉多次返回急诊科时保持广泛鉴别诊断并仔细排除诊断的重要性。
