Herein, a case of missed upper lumbar disc herniation, diagnosed by thorough neurological examination, digital infrared thermographic imaging[DITI], and repeated magnetic resonance[MR] image study, is reported. A 36-year-old female presented with intractable leg pain on left anterior thigh. Although she underwent lumbar MR image at other hospital, she was misdiagnosed as acute sprain. Neurological examination suggested the possibility of upper lumbar disc herniation, which was confirmed by DITI, MRI, and selective root block. After operation, her leg pain was significantly improved. It should be considered that upper lumbar disc herniation might be misdiagnosed as an acute sprain, as in our case. A high index of suspicion based on thorough neurological examination is most important in such cases. Then, multi-access such as DITI, MR image, and selective block, base on thorough neurological examination, are warranted.

The field size of the lumbar spine X-ray examination, which belongs to the most frequent examination in general radiography, is 5 times wider than the width of the lumbar spine. Exposure index (EI) as per International Electrotechnical Commission has a proportional relationship with the dose incident on the image receptor for clinical protocols in addition to RQA5, which is a calibration beam quality. In this study, the effectiveness of the set field size was evaluated through the change of EI according to the size of field during lumbar spine X-ray examinations. Lumbar anterior-posterior and lateral examinations was performed using a whole-body phantom, and the national average exposure conditions of Korea investigated in 2017 were introduced for the X-ray exposure. As a result of comparing the EI displayed on the console of digital radiography system for the three field size in ① 18 × 36 cm2 ② 25 × 36 cm2 ③ 36 × 36 cm2, the EI values showed a tendency to increase as the field size increased. Since the patient dose, such as organ dose around the lumbar spine, increases as the field size becomes larger, thus, if the EI obtained from the field size at a level that does not interfere with diagnosis is set as a reference, the effectiveness of the field size can be evaluated through the EI displayed on the console when the lumbar spine X-ray examination is conducted.

The diagnosis of peripheral neuropathy had been performed by electrophysiologic studies and neurologic examination. However, Magnetic Resonance Imaging (MRI) has recently been proposed as a supplementary tool for its diagnosis. A 55-year-old woman presented with back pain and painful proximal weakness of the right leg. Neurologic examination and electrophysiologic studies suggested an upper lumbar plexopathy. MRI disclosed the signal change in lumbar plexus with the atrophy of the innervating muscles. We report a patient with idiopathic lumbar plexopathy confirmed by MRI.

Intervertebral intradural lumbar disc herniation (ILDH) is a quite rare pathology, and isolated intradural lumbar disc herniation is even more rare. Magnetic resonance imaging (MRI) may not be able to reveal ILDHs, especially if MRI findings show an intact lumbar disc annulus and posterior longitudinal ligament. Here, we present an exceedingly rare case of an isolated IDLH that we initially misidentified as a spinal intradural tumor, in a 54-year-old man hospitalized with a 2-month history of back pain and right sciatica. Neurologic examination revealed a positive straight leg raise test on the right side, but he presented no other sensory, motor, or sphincter disturbances. A gadolinium-enhanced MRI revealed what we believed to be an intradural extramedullary tumor compressing the cauda equina leftward in the thecal sac, at the L2 vertebral level. The patient underwent total L2 laminectomy, and we extirpated the intradural mass under microscopic guidance. Histologic examination of the mass revealed a degenerated nucleus pulposus.

본 연구의 목적은 디지털 방사선 장비를 이용하여 요추 측면 검사 시 사용되고 있는 조사야 크기 및 조사야 크기에 영향을 미치는 요인의 상관관계 분석을 통해, 적절한 조사야 크기 및 중심 엑스선 입사지점을 제안하는데 있다. 2023년 1월 1일부터 2023년 12월 31일까지 S병원 영상의학과에서 요추 측면 검사를 시행한 환자 중 본 연구 목적에 적합한 148명의 검사 결과를 분석하였다. 측정 방법은 영상에서 나타난 전체 가로 폭을 검사 시 사용된 조사야 가로폭의 크기(CS)로 설정하고, 영상에 포함된 등쪽 조사야 끝에서부터 제 3요추의 척추 돌기관절까지 수직으로 연결한 거리(AJD), 영상의 조사야 등쪽 끝 부분에서 제 3요추 몸통 중심까지의 거리(BD), 영상의 등쪽 조사야 끝 부분에서 제 3요추의 척추 경 중심까지의 거리(PD)를 측정하였다. 성별, 연령, 신장, 체중, 체질량지수에 따른 종속변수의 평균값의 비교분석을 위해 독립표본 t 검정과 일원배치분산분석을 이용해 평균값을 비교하였으며, 사후분석으로는 duncan을 이용했다. 독립변수와 종속변수 간의 상관성은 pearson 상관분석을 통해 분석하였다. 본 연구에서 통계적 유의성은 p값 0.05 이하를 유의한 것으로 설정하였다. 요추 측면 검사 시 CS의 평균값은 252.45 mm 였으며, AJD는 102.11 mm, BD는 141.17 mm, PD는 119.73 mm로 나타났다. CS 및 AJD, BD, PD는 남성이 여성에 비해 평균값이 크게 나타났으나, 성별에 따른 평균값 차이에 대한 통계적 유의성은 BD에서만 나타났다(p<0.05). 연령에 따른 그룹별 평균값에 약간의 차이는 있었지만 통계적 유의성은 없었다(p>0.05). 신장, 체중, 체질량지수에 따른 CS 및 AJD, BD, PD의 평균값은 독립변수에 따라 차이가 있었으며, 그 차이는 모두 통계적으로 유의한 차이를 보였다(p<0.05). 상관관계 분석 결과, 조사야 크기 및 AJD, BD, PD는 성별, 연령과는 상관성이 없었으며, 신장과는 약한 양의 상관관계를 보였고, 체중과 체질량지수와는 중간 정도 양의 상관관계를 나타냈다. 본 연구의 결과 요추 측면 검사 시 CS는 신장과 체중, BMI와 상관성이 있는 것으로 나타났다. 그리고 임상에서 조사야 크기 조절시 체중과 체질량지수를 고려하여 중심 엑스선의 입사점을 척추 돌기관절로 이동시킨다면, 약 5%의 조사야 크기 감소 효과를 기대할 수 있을 것으로 생각된다.
