Magnetic resonance image (MRI) findings in the spinal cord. (A) abnormal longitudinally extensive T2 weighted hyperintensities involving the posterior columns (the red arrow) (B) inverted V or "rabbit ears" sign on cervical spinal (the red arrow). (C) abnormal hyperintensities involving the posterior columns disappeared in MRI after treament. (D) recovered MRI image on cervical spinal after treament.

Cervical spinal cord MRI showed abnormal longitudinally extensive T2 weighted hyperintensities involving the posterior columns ( Figure 1A ), with inverted V or "rabbit ears" sign ( Figure 1B ). After 1 year of follow-up, her spinal cord imaging results were completely normal except for age-related degenerative changes ( Figures 1C, D ).
Gastroscope shows the atrophic gastritis in fundus (A) and corpus(B), superficial gastritis in autrum (C) and a gastric polyp (arrow) in the corpus (D).

A red, 0.4x0.8 cm and Yamada type 2 polyp was found in the corpus ( Figure 2 ).
Histopathology of gastric mucosa and labial salivary gland. (A) Hematoxylin and eosin staining (40x) displays a hyperplastic polyp in the corpus. (B) Hematoxylin and eosin staining (100x) displays the background of the hyperplastic polyp: atrophy, intestinal metaplasia and pseudo-pyloric adenylation in the mucosa. (C)Immunohistochemical staining of gastrin is negative in pseudo-pyloric gland. (D) Staining with anti-chromogranin antibodies (CgA) (100x) depicts dark brown endocrine cells (arrow). (E) Hematoxylin and eosin staining (100x) displays no obvious atrophy in the acinus of the labial salivary gland, but small and numerous foci of lymphocytic aggregation was observed (arrow). (F) The arrow indicates the squeeze of the lymphocytes.

Immunostaining of gastric corpus with gastrin and anti-chromogranin antibodies revealed that pseudopyloric metaplasia had replaced oxyntic mucosa, and endocrine cells presented with a micronodular hyperplasia pattern ( Figure 3 ). Eye test showed ocular staining scores on two eyes were >5 Labial salivary gland histopathology indicated no obvious atrophy in the acinus, but small and numerous foci of lymphocytic aggregation were observed (50-80 lymphocytes/HPF;  Figure 3 ), and focus score was 10.8.
