We herein report a 90-year-old immunocompromised woman who developed right upper limb weakness and right ptosis with a miotic pupil 1 week after oral therapy for zoster on the right T2 dermatome. The right pupil was dilated with instillation of 1% apraclonidine, indicating Horner's syndrome. ⋯ Focal weakness related to zoster, generally known as segmental zoster paresis, improved over five months, but Horner's syndrome remained. We suggest that aggressive intravenous treatment should be considered for rare cases of zoster that occur with a combination of these two neurological conditions.

Case Reports
Orofacial Dyskinesia and Intractable Hiccups in a Patient with Varicella-Zoster Virus Encephalomyelitis.
A 73-year-old Japanese man with diabetic complications presented with involuntary lip movements and long-lasting hiccups after developing zoster rash. Magnetic resonance imaging revealed lesions involving the medial temporal lobe and C1 level of the spinal cord. ⋯ Although the culprit lesion for the hiccups was unclear, further examinations may have clarified this issue. As immunocompromised patients with herpes zoster may develop CNS complications with a wide variety of symptoms, special care is needed.

A 35-year-old woman was treated with chemotherapy for leukemia. One year later, allogeneic hematopoietic stem cell transplantation (HSCT) was performed with umbilical cord blood. After nine months, she developed a spiking fever, sore throat, arthralgia, pleural effusion, hyperferritinemia, and persistent generalized pruritic erythema. ⋯ Treatment with tocilizumab was effective. Adult-onset Still's disease (AOSD)-like disease related to graft versus-host disease (GVHD) after HSCT was suspected. Abnormal immune states related to GVHD may cause AOSD-like disease with more severe skin lesions than usual.

A 54-year-old man whose awake percutaneous arterial oxygen saturation (SpO2) was 94% was diagnosed with obstructive sleep apnea by polysomnography (PSG). His apnea-hypopnea index (AHI) was 138.8 (AI: 4.7 and HI: 134.1), so he was treated with continuous positive airway pressure (CPAP), and his condition was considered well-controlled by the CPAP tracking system (AHI=3.4), with improvement seen in his symptoms when he left our hospital. ⋯ His hypercapnia improved following voluntary hyperventilation. Idiopathic central alveolar hypoventilation was diagnosed, with the AHI considered to be well-controlled by the CPAP tracking system but not at all according to PSG.

Case Reports
Hereditary Neuralgic Amyotrophy with a Lesion Distal to the Brachial Plexus on Magnetic Resonance Imaging.
A 35-year-old woman first experienced left upper limb weakness at 17 years old, after which it repeatedly recurred and then remitted. She was diagnosed with carpal tunnel syndrome with median nerve hyperintensity by magnetic resonance imaging (MRI). ⋯ Genetic testing revealed a point mutation in SEPT9. Because lesions outside the brachial plexus can be seen in hereditary neuralgic amyotrophy, the diagnosis should be based on typical characteristics and the family history.
