Introduction Disseminated herpes zoster is defined as at least 20 skin lesions in multiple dermatomes. In particular, it has been reported mainly in patients with immunological defects. To our knowledge, there is no reported case of disseminated zoster in a non-immunocompromised patient with leg radiating pain and weakness. Case presentation A 74-year-old man visited our hospital with left leg radiating pain and left hip pain. He had no underlying disease other than hypertension. Neurologic examination revealed radiating pain on the L4 dermatome of the left leg. The muscle power was grade 3 for the hip flexor and knee extensor, and grade 4 for the ankle dorsiflexor and big toe dorsiflexor of the left leg. There were no sensory changes or skin lesions on his left leg. Herniation of the nucleus pulposus of the lumbar spine was suspected and lumbar magnetic resonance imaging (MRI) was performed. However, no pathologic lesions were seen on lumbar MRI. On the third day of hospitalization, erythematous patches and vesicles were observed on the head, face, ear, neck, trunk, back, and both lower extremities. Herpes zoster infection was confirmed by polymerase chain reaction analysis. Treatment was performed with 250 mg of intravenous acyclovir every 8 hours for 6 days and 62.5 mg of intravenous methylprednisolone for 4 days. On the 13th day of hospitalization, the skin lesions and left leg radiating pain and weakness improved. Conclusion We report the first case of disseminated herpes zoster involving the whole body in a non-immunocompromised patient complaining of left leg radiating pain and weakness. After treatment, both the patient’s radiating pain and weakness improved.

Background Iliac artery occlusion accompanied by spinal canal stenosis is rare. All reported cases were treated with endovascular stenting for iliac artery occlusion. We report the first case of external iliac artery occlusion accompanied by spinal stenosis, which was successfully treated with conservative treatment. Case presentation A 66-year-old man with lower extremity pain and claudication visited the outpatient spine clinic. He complained of a tingling sensation in the L5 dermatome of the right leg and L4 dermatome of the left leg. Magnetic resonance imaging showed central stenosis in at the L4–5 and L5–S1 levels, and lateral recess stenosis at the L5–S1 level. The patient's symptoms were ambiguous with mixed neurological claudication and vascular claudication. Computed tomography of the lower extremity artery showed complete occlusion in the right external iliac artery. Conservative treatment with clopidogrel and beraprost sodium was performed. After treatment, his symptoms gradually improved. Clopidogrel and beraprost sodium were continued for 4 years. Follow-up computed tomography at 4 years showed recanalization of the right external iliac artery occlusion. Conclusions We describe a rare case of external iliac artery occlusion and spinal stenosis. External iliac artery occlusion may be successfully treated only with conservative treatment using medication.
