The objective is to report the case of a Transmontano Mastiff dog, eight year old intact male, 88 kg, with history of visual loss, diffuse corneal edema and secondary glaucoma. The ocular ultrasound examination revealed a hyperechoic structure located in the peripapillary region of the optic nerve, showing an image compatible with intraocular neoplasia. The animal was submitted to the enucleation procedure and anatomopathological analysis of the affected eye was performed. Histological examination revealed glioma of the optic nerve, considering that neoplasms that affect the retina and optic nerve are rarely described in veterinary medicine, as the case presented.

Memory Disturbance

Introduction: Meningiomas are the third most common intracranial tumors in adults after glial tumors and metastases. Olfactory groove meningiomas often grow without symptoms due to their slow growth rates and location in the frontal lobe. Optic nerve sheath meningiomas are benign neoplasms of the meninges surrounding the optic nerve. The coexistence of olfactory groove and optic nerve sheath meningiomas without any history of neurofibromatosis or radiotherapy has never been reported in the literature. Case Report: A 36-year-old female patient presenting with anosmia, headache, memory disturbance, and visual impairment and operated with the diagnosis of olfactory groove meningioma was reported. In the postoperative period, optic nerve sheath meningioma was detected in the imaging performed due to the persistence of visual impairment. Conclusion: Olfactory groove and optic nerve sheath meningiomas are rare tumors and can be diagnosed late because they progress slowly. Early diagnosis and treatment may affect the prognosis and morbidity of these patients favorably.

This is a rare case of a wild squirrel that was diagnosed with angiostrongyliasis characterized by the presence of larvae-induced eosinophilic meningoencephalomyelitis. A wild, intact, male Pallas’s squirrel (Callosciurus erythraeus) of unknown age was presented with a history of progressive paralysis in both forelimbs and hindlimbs. Gradually, the squirrel showed signs of deterioration, found dead and submitted for a complete pathological diagnosis. Necropsy revealed the presence of severe and diffuse congestion in the subarachnoid space of the brain and mild congestion in the spinal cord. Microscopically, severe meningoencephalomyelitis and interstitial pneumonia were consistent with lesions induced by Angiostrongylus cantonensis (A. cantonensis). Although A. cantonensis has been widely studied in rabbits, mice and humans, infection in squirrels has not been documented. This may be the first reported case of angiostrongyliasis in the Pallas’s squirrel.

Introduction: Toxic optic neuropathy is defined as the damage caused by a toxin to the optic nerve fibers. There is a vast list of toxins that may lead to optic neuropathies. One of the toxins among this list is tobacco. Gutka being an oral form of tobacco, however, has not been previously related to optic neuropathy. Case presentation: We present a case of a 22-year-old male who presented with decreased far vision and gradually increasing photophobia. He had a history of gutka usage, a form of smokeless tobacco. Investigations revealed a central scotoma on FOV, a swollen optic disc on OCT and deranged Liver function tests. A diagnosis of RIGHT + LEFT optic neuropathy secondary to a chemical toxic was made, which in this case, was gutka. Conclusion: Consumption of gutka can lead to irreversible toxic optic neuropathy.

Sphenoid Wing Meningioma

Foster Kennedy syndrome is a rare neurological condition with ophthalmic significance that can manifest as acute visual loss. It is classically characterised by unilateral optic nerve atrophy and contralateral papilledema resulting from an intracranial neoplasm. Physicians should consider Foster Kennedy syndrome in patients who present with visual loss and who have a history of intracranial neoplasm. In addition to ophthalmologic examination, neuroimaging is essential for the diagnosis of Foster Kennedy syndrome.

A 7-y-old, intact male Alaskan Malamute was presented with a 3-mo history of stertor and epistaxis. Computed tomography of the skull revealed generalized loss of gas throughout both nasal passages with replacement by a soft tissue mass that traversed the cribriform plate. Histopathology revealed neoplastic neuroblast cells arranged in anastomosing cords, as well as separately located aggregates of ganglion cells. Both neoplastic cell populations demonstrated immunoreactivity to MAP-2, TuJ-1, and synaptophysin. Neuroblastic cells additionally exhibited punctate immunoreactivity to MCK and CK8/18. We document here both the positive neural immunohistochemical markers for this neoplasm, as well as propose possible histomorphologic variants.

Secondary glaucoma following blunt trauma is relatively uncommon in regular optometric practice. Onset of this type of glaucoma may occur within weeks, but may also be delayed several decades. This case report presents a 57 year old male who, 48 years ago, suffered a sling shot accident yet was only recently diagnosed with traumatic glaucoma in his left eye. The trauma caused severely reduced vision in his left eye but, aside from this, the patient did not report any eye- or vision problems and he had never had an eye examination as an adult. He successfully wore ready-made glasses for near work. While all findings were normal in his right eye, his left eye showed reduced vision, inferionasal iridodialysis, angle recession, increased intraocular pressure and heavily excavated optic nerve head. The patient was referred to an ophthalmologist who confirmed unilateral glaucoma. The case report reviews situations where secondary glaucoma from blunt trauma may occur, which ocular signs might be present and which ocular examinations should be undertaken. Further, the importance of following up patients with ocular trauma is discussed.

Abstract Background: The peripapillary staphyloma (PS) is a rare non-hereditary congenital optic disc dysplasia, which is generally unilateral and is likely to occur with poor vision. Fundus uncovered a large deeply excavated optic nerve head, retinal pigment epithelium changes at its edges and normal disc and retinal blood vessels in size and features. Case presentation: This literature present a bilateral case of an especially congential peripaillary staphyloma (CPS), which the patient with esotropia and nystagmus was exposed to abnormality when she was only 5-month-old. Several interesting features are present in this patient. Conclusions: Usually they have a large extent on visual loss. Thus, although extreme rare, an early detection, treatment and follow ups are necessary. Keywords: Staphyloma; optic nerve; congenital

Madelung’s disease is a rare disorder characterised by excessive and symmetrical deposits of adipose tissue, typically in the cervicofacial region. Alcohol is a known cause of the condition, however, there are reports that this condition is genetically inherited. Lipomatosis of the orbit has been described in the alcoholic Madelung’s disease, however, in our case report, we believe this is the first reported instance of proptosis caused by the genetic form of the condition. We present a 69-year-old woman, with a medical history of genetic Madelung’s disease, who presented with bilateral proptosis worse in her right eye. Her ocular examination was normal apart from exophthalmometry, showing bilateral proptosis. This was confirmed by an MRI, which further showed intraorbital fat deposition bilaterally. Due to the stability of her condition, no treatment was deemed necessary. We highlight the importance of monitoring for progressive optic nerve compromise and liposarcomatous malignant transformation.

Pelvic Cyst

Anterior sacral meningocele is characterized by herniation of the meningeal sac due to a developmental bone defect in the front of a sacrum bone. It was first described in 1837. The sacral meningocele may be congenital or acquired. It is usually discovered during a rectal or pelvic examination as a cystic lesion or discovered incidentally. Most of the symptoms are due to compression on the adjacent organs. In this paper, we present a case of an asymptomatic female patient who had a pelvic cyst detected during a routine obstetric ultrasound examination. We show radiological findings of the detailed postpartum evaluation of the cyst, which led to detection of sacral agenesis, huge anterior sacral meningocele, and significant arcuate uterus.

A case of a two-year-old male Pinscher with a history of discomfort in the right eye was reported. The left eye had been enucleated by the referring veterinarian due to the same symptom with unsuccessful clinical treatment. The Schirmer tear test value was elevated and a decreased intraocular pressure was observed by applanation tonometry. Biomicroscopy revealed profuse corneal edema and keratoconus and fluorescein staining was negative. Gonioscopy and ophthalmoscopy did not provide any relevant data due to the corneal alterations. Bullous keratopathy was diagnosed. Surgery was performed in two steps: 1) superficial keratectomy and 360º conjunctival flap, and 2) superficial keratectomy to restore corneal transparency. Thirty days after the second superficial keratectomy, the third eyelid flap was removed. Conjunctivalization of the upper nasal quadrant of the cornea was observed. The axial portion of the cornea was transparent and vision was restored.
