Abnormalities in genes on the X chromosome or large defects in the X chromosome itself cause X-linked intellectual disability. The proband was a 27-year-old man. His medical history included strabismus, cryptorchidism, and severe intellectual disabilities. ⋯ The lateral and fourth ventricles were dilated using computed tomography. CGG repeats in the 5' untranslated region of FMR1 gene were normal. G-banding and spectral karyotyping revealed a novel unbalanced X-autosomal translocation, with a karyotype of 46,Y,der (X) t (X;9) (p22.33;p12); distal trisomy of 9p and distal Xp nullisomy.

Cases of neuronopathy associated with immune checkpoint inhibitors (ICIs) have rarely been reported. We herein report a case of ICI-associated neuronopathy. A 54-year-old man underwent chemotherapy for right maxillary sinus cancer. ⋯ A colonic biopsy suggested ICI-associated colitis. Based on these findings, the patient was diagnosed with ICI-associated neuronopathy. Clinical symptoms and SEP findings improved markedly after two courses of intravenous methylprednisolone.

A 65-year-old man with generalized lymphadenopathy was diagnosed with classical Hodgkin lymphoma-Mixed cellularity via left cervical lymph node biopsy. Initial treatment with doxorubicin, bleomycin, vinblastine, and dacarbazine led to complete metabolic remission (CMR); however, recurrence developed after 6 months. Brentuximab vedotin induced partial remission followed by systemic relapse after 10 months. ⋯ Eventually, the patient was diagnosed with diffuse large B-cell lymphoma during routine esophagogastroduodenoscopy. Four courses of rituximab-CHOP therapy led to a CMR. This case highlights the importance of performing re-biopsies to detect the recurrence or progression of lymphoma.

A 69-year-old man was admitted to our hospital because of a sudden gait disturbance. Based on the neurological examination performed upon admission, the patient exhibited ataxic movement in his right lower limb and body lateropulsion toward the right side. ⋯ A motion analysis revealed ipsilateral lower-limb ataxia. Lower lateral medullary infarction can cause ipsilateral lower limb ataxia, particularly impaired hip joint coordination, resulting in body lateropulsion in dynamic conditions.
