Dandy–Walker syndrome associated with syringomyelia is a rare condition, with few reports of adult cases. We describe an adult case of Dandy–Walker syndrome with concomitant syringomyelia. A 33-year-old man presented with a 3-month history of walking instability, numbness in the hands, memory deterioration, and urinary incontinence. A physical examination showed a positive Romberg sign. Brain computed tomography and magnetic resonance imaging showed hydrocephalus, a cyst in the posterior fossa, absence of the cerebellar vermis, hypoplasia of the corpus callosum and cerebella, and syringomyelia. All of these symptoms were consistent with the diagnosis of Dandy–Walker syndrome. Surgery involving arachnoid adhesiolysis and endoscopic third ventriculostomy was performed. At the 6-month follow-up, the symptoms were completely relieved. Magnetic resonance imaging showed that syringomyelia was greatly reduced and the hydrocephalus remained unchanged. Dandy–Walker syndrome with concomitant syringomyelia in adults is exceedingly rare. Early diagnosis and appropriate surgical treatment of this condition should be highlighted. Combined arachnoid adhesiolysis and endoscopic third ventriculostomy may be an effective approach.

Abstract Stereotactic radiosurgery has been shown to treat successfully angiographically demonstrated arteriovenous malformations of the brain. Angiographic obliteration has represented cure and eliminated the risk of future hemorrhage. The role of radiosurgery in the treatment of angiographically occult vascular malformations (AOVMs) has been less well defined. In the initial 32 months of operation of the 201-source cobalt-60 gamma knife at the University of Pittsburgh, 24 patients meeting strict criteria for high-risk AOVMs were treated. Radiosurgery was used conservatively; each patient had sustained two or more hemorrhages and had a magnetic resonance imaging-defined AOVM located in a region of the brain where microsurgical removal was judged to pose an excessive risk. Venous angiomas were excluded by performance of high-resolution subtraction angiography in each patient. Fifteen malformations were in the medulla, pons, and/or mesencephalon, and 5 were located in the thalamus or basal ganglia. Follow-up ranged from 4 to 24 months. Nineteen patients either improved or remained clinically stable and did not hemorrhage again during the follow-up interval. One patient suffered another hemorrhage 7 months after radiosurgery. Five patients experienced temporary worsening of pre-existing neurological deficits that suggested delayed radiation injury. Magnetic resonance imaging demonstrated signal changes and edema surrounding the radiosurgical target. Dose-volume guidelines for avoiding complications were constructed. Our initial experience indicates that stereotactic radiosurgery can be performed safely in patients with small, well-circumscribed AOVMs located in deep, critical, or relatively inaccessible cerebral locations. Because cerebral angiography is not useful in following patients with AOVMs, long-term magnetic resonance imaging and clinical studies will be necessary to determine whether the natural history of such lesions is changed by radiosurgery.

This paper reviews the clinical and radiographic features and treatment results in eight patients with intraosseous epidermoid cysts in the terminal phalanx of a finger seen over a period of 26 years. Data on age, sex, occupation, diagnostic findings, history of injury in six cases, treatment and follow-up were obtained by reviewing medical records and the histopathological findings using the hospital database. The most frequent symptoms of pressure pain, tenderness, redness and swelling occurred at a median time of 12 years after trauma. Male patients were mainly affected (7:1). In four the intraosseous epidermoid cysts were confused with other osteolytic diseases before surgery. Magnetic resonance imaging is recommended in any case of an osteolytic, expanding lesion, particularly in cases that are clinically and radiologically not obviously an intraosseous epidermoid cyst.

Abstract Background Extradural intraspinal cysts are fluid accumulations that appear to be associated with increased motion at vertebral joints. Case presentation We report the spontaneous regression of lumbar and lumbosacral cysts (presumably synovial cysts) and the unusual occurrence of an S1–2 extradural intraspinal cyst in a dog. The dog presented with lumbosacral pain. Six extradural intraspinal cysts were observed on high-field magnetic resonance imaging from L5–6 to S1-S2. The cysts between L5–6 and L7-S1 ranged from 0.12 to 0.44cm2 at their largest area. The largest cyst was located at S1–2 (left), measuring 0.84 cm2 at its largest view. The dog was medically managed. A follow-up magnetic resonance imaging scan was obtained 3.5 years after the first imaging. All cysts except the one at S1–2 had reduced in size. Mean reduction in size was 59.6% (35–81%). Conclusions In summary, we report a case with multiple extradural intraspinal cysts that underwent spontaneous regression of all but one cyst during a 3.5-year follow-up period. Whether this is a single occurrence, or is part of the natural history of these cysts in the lumbosacral region of dogs, remains to be established. Spontaneous regression of intraspinal cysts had not been described in dogs.

Pituitary apoplexy is a rare condition which may cause death of the patient in severe cases and many times leads to hypopituitarism. We report a case of apoplexy in a large prolactinoma resulting in empty sella syndrome followed by a successful pregnancy. Our patient is a 32-year-old female with a history of a macroprolactinoma for approximately 17 years who presented to our hospital with a history of severe headache, decreased level of consciousness, fever, nausea, vomiting, and diplopia of 12 hours duration. Magnetic resonance imaging done on admission showed an increase in the size of the pituitary adenoma with a subtle hemorrhage. The patient was admitted to the intensive care unit and treated conservatively. The condition of the patient improved within a few days. A few months later, she started having regular menstrual periods. A magnetic resonance imaging of the pituitary 1.5 years later was reported as empty sella syndrome, and approximately one year later she became pregnant. With the pituitary adenoma being resolved after developing pituitary apoplexy and continuing on cabergoline, the patient had a successful pregnancy with no recurrence of the adenoma after delivery and breastfeeding.

Retrobulbar Hemorrhage

Background. Spontaneous orbital haemorrhage is a very rare condition and vision-threatening event. It may occur due to trauma, orbital surgery/injections, orbital vascular anomalies, and a variety of systemic predisposing factors. Signs of retrobulbar hemorrhage include proptosis, ophthalmoplegia, increased intraocular pressure, loss of pupillary reflexes, and optic disc or retinal pallor. Both Computed Tomography scan and Magnetic Resonance Imaging may be performed in the diagnosis.Case Report. A 31-year-old woman was referred to our hospital with a complaint of headache and blurred vision following a strong sneeze. Ophthalmological examination revealed mild Relative Afferent Pupillary Defect in left eye. Computed Tomography revealed left hyperdense retrobulbar mass and displaced optic nerve. T1 weighted hypointense, T2 weighted hyperintense and non-enhanced round shape, sharply demarcated lesion measuring 18 × 15 × 14 × mm in diameter compatible with haematoma was detected by MRI. Surgically Caldwell-Luc procedure was performed. Histological examination confirmed haematoma. Follow-up Magnetic Resonance Imaging revealed a small reduction in the size of lesion but not complete resolution. The patient’s complaint was regressed. She is now free of symptoms and is still under surveillance. To our knowledge, this is the first reported case of retrobulbar haematoma caused by sneeze.

A 4-year-old, male Jack Russell terrier was presented for a 6-month history of progressive right hemiparesis with episodic cervical hyperesthesia. The neurological examination showed a right-sided, upper motoneuron syndrome and partial Horner’s syndrome. Two magnetic resonance imaging (MRI) examinations were performed 3 months apart and revealed a persistent cervical intramedullary hematoma. A dorsal myelotomy was performed. A subacute hematoma was confirmed histologically without underlying lesions. Eighteen months later, the dog’s clinical signs were minimal. Two MRI examinations were performed 2 weeks and 5 months after surgery and revealed regressing signal abnormalities at the surgical site, consistent with a surgical scar.
