“…To our knowledge this is the first case report in the veterinary literature of a cat with a dermoid sinus located in the dorsal midline, associated with vertebral malformations and an intradural component causing spinal deficits. The few dermoid sinuses previously reported in the cat were described as occurring in the flank 15 or intracranially 16 …”

A 2-year-old, male, Burmese cat was evaluated for chronic progressive hindlimb weakness, ataxia and urinary incontinence. Radiographic examination, myelography and magnetic resonance imaging defined congenital vertebral anomalies and a space-occupying intradural, extramedullary mass. A dermoid sinus was subsequently identified dorsal to the affected spine. Surgical excision of the tract necessitated a dorsal laminectomy and removal of a 1-cm diameter intradural dermoid sinus 'cyst' that contained hair and sebaceous debris. The cat recovered hindlimb function after surgery and remains asymptomatic 50 months after surgery except for a persistent inability to urinate voluntarily.

“…The neoplastic transformation of these cells is very rare [14]. In a normal situation extragonadal germ cells disappear in foeti older than 60 days [7]. In humans, sacrococcygeal teratoma is a neoplasm arising in the sacrococcygeal region [16] and there were suggestions that it originated from multipotential cells in Henson’s node, which migrates caudally to the coccyx.…”

An unusual case of a mature teratoma on the left perineal region of a young cat: surgical treatment and pathological description

et al. 2013

A 10-month-old intact male cat with a clinical history of a large mass in the left perineal region was submitted to the surgery department. The mass had reportedly been present as a small swelling after birth. Cytological evaluation using a fine-needle aspirate showed eosinophilic keratinaceous debris, and was not convincing for the definitive diagnosis. Complete surgical excision was performed. Postoperative function and aesthetics were excellent. Based on gross and histological features the definitive diagnosis of the tumor was mature teratoma with ectodermal and endodermal components. After a follow-up period of 4 months, no signs of recurrence were evident. Surgical excision of the teratoma in our case was considered curative. A perineal location has not been previously reported in the cat and should be considered a rare condition in this species.

“…Cholesterol granulomas are rare in cats and only one case in the cerebrum has been reported. 13 Other intracranial masses in which cholesterol crystals have been reported include dermoid cysts 14 and craniopharyngiomas, 15 both rarely reported in cats. In addition, these lesions typically contain keratin and dermal adnexa (dermoid cyst) or epithelial cells and focal areas of keratin accumulation (craniopharyngioma), which were not observed in this case.…”

“…In addition, these lesions typically contain keratin and dermal adnexa (dermoid cyst) or epithelial cells and focal areas of keratin accumulation (craniopharyngioma), which were not observed in this case. 14,16 Although few intracranial tumors have been reported to contain cholesterol clefts or crystals, cholesterol crystals could potentially form in any intracranial mass or lesion with chronic hemorrhage or fluid accumulation.…”

A 14-year-old female spayed cat was presented with a 3-4-month history of circling to the left and intermittent head pressing. Neurologic examination findings localized the lesion to the left supratentorial region. Using magnetic resonance imaging, an extra-axial mass was found on the dorsal aspect of the brain at the level of the frontal and parietal lobes, compressing and displacing the brain ventrally and caudally. Craniectomy was performed and the mass was submitted for cytologic and histopathologic evaluation. Impression smears revealed abundant cholesterol crystals and loose clusters of mildly pleomorphic spindle cells, compatible with a meningioma. The histopathologic diagnosis was meningioma with psammoma bodies and numerous cholesterol clefts. Abundant cholesterol crystals within meningiomas in cats may present a diagnostic challenge when nucleated cells are scant. Other differential diagnoses for abundant cholesterol crystals in an intracranial mass include cholesterol granulomas and keratinizing cysts.
