The aim of this retrospective multicentric case series is to describe the CT findings of ovarian neoplasia in dogs. Twenty dogs with pre- and postcontrast CT exams and cytological/histological diagnosis of ovarian neoplasia were included. Five dogs presented with bilateral tumors, for a total of 25 neoplasms: 15 carcinomas (4 bilateral), 4 granulosa cell tumors, 2 poorly differentiated malignant neoplasia (bilateral), 2 luteomas, 1 teratoma, 1 dysgerminoma.

To investigate the relationship between the expression patterns of SOX2 and FOXG1 and the differentiation/development level of neural components in immature teratoma and to determine the clinical significance and potential application of this correlation in a clinical setting. We conducted a comprehensive whole transcriptome sequencing analysis to identify differentially expressed genes (DEGs) across various subtypes of ovarian germ cell tumors. Additionally, immunohistochemical staining of paraffin-embedded tissue sections was employed to assess the nuclear staining pattern of SOX2 and FOXG1 proteins within the tumor tissues.

Background: Malignant dysgerminomas are infrequently reported ovarian neoplasms in animals, especially in exotic pets (non-traditional companion animals [NTCAs]). In the few published case reports on reptilian species, examples are primarily postmortem without antemortem (clinical) assessment.
Patient Presentation: An adult, 13-year-old, spayed female inland bearded dragon (Pogona vitticeps) presented with lethargy, a right-sided head tilt, unilateral exophthalmos and ventrotemporal strabismus on the right eye.
