We present the case of a 66 year old gentleman with trigeminal schwannoma whose only presenting feature was a single gelastic seizure. This is the first case report of pathological laughter in trigeminal schwannoma in the absence of other trigeminal, brainstem, cerebellar or other cranial nerve
Intraparenchymal schwannomas of the brain are very rare, accounting for < 1% of intracranial schwannomas. We present a case of an 11-year-old boy with a left frontotemporal lobe schwannoma presented with seizure and neurogenic pulmonary edema. To our knowledge, this is the first case of
Neurofibromatosis 1 (NF1) is the most common neurocutaneous syndrome. It is estimated to occur in approximately 1 out of every 3300 infants. The manifestations of this condition are diverse and can arise from almost any system in the body. The neurofibroma is the hallmark lesion of NF1 that develops
Schwannomas are the most common tumor of peripheral nerves which are arising from Schwann cells and are benign in their nature. Intracranial schwannoma accounts for between 5 and 8% of intracranial tumors, whereas intracerebral schwannoma, a rare disease, accounts for <1% of intracranial
Schwannomas of the brain parenchyma are extremely rare, occurring mostly in children and young adults. Fewer than 50 cases have been reported in the English-language literature. Isolated temporal lobe epilepsy is a rare presentation of intracerebral schwannomas, with only 2 reported cases. The
BACKGROUND
Patients with physical brain abnormalities have an increased risk of developing psychogenic nonepileptic seizures (PNES). Here we describe patients who developed PNES after intracranial neurosurgery for indications other than the control of refractory epileptic seizures and explore
A 39-year-old female had been subject to headache, and intermittent seizures for 9 years and decreasing memory for one year, without obvious neurological signs. An MRI revealed a 2x2 cm contrast-enhanced lesion in the frontal lobe, with a cyst and peritumoral edema, which was not attached to the
METHODS
A 13-year-old male with an 11-year history of a seizure disorder presented with recent onset raised intracranial pressure symptoms and no obvious phakomatosis. CT revealed a heterogeneous, frontal, intra-axial, densely enhancing, solid lesion with intense perilesional oedema and mass effect.
Intracranial intraparenchymal Schwannomas are very rare. Twenty-eight cases of frontal intraparenchymal Schwannomas have been reported so far. These generally present with seizures, raised intracranial pressure, nasal stuffiness and epistaxis. We present a patient with frontal intraparenchymal
A 38-year-old intact female Grizzly bear (Ursus arctos horribilis) was evaluated for progressive seizure activity, pale mucous membranes, deficient pupillary light and menace responses, and irregular shallow respiration. Because of poor response to treatment, the animal was euthanized. Gross
BACKGROUND
Posterior reversible encephalopathy syndrome (PRES) is a constellation of neurologic symptoms-seizures, headaches, altered mental status, and visual changes-associated with characteristic brain magnetic resonance imaging findings seen on T2 and fluid-attenuated inversion recovery
METHODS
An 8-year-old boy presented to the emergency department after a generalized tonic-clonic seizure that lasted for 5 min. Magnetic resonance imaging showed a 2x2 cm, intraaxial, contrast-enhanced cortical lesion in the posterior right frontal lobe. On several images the lesion appeared to be
Intracranial schwannomas not associated with cranial nerves are rare and seldom encountered in the subfrontal region. We report a case of subfrontal schwannoma in a 21-year-old man who presented with seizures. Radiological features resembled an olfactory groove meningioma. The histological diagnosis
Intracerebral schwannomas are quite rare. Due to their rarity and lack of pathognomonic imaging features, intracerebral schwannoma may be overlooked in the initial differential diagnosis of an intra-axial mass with heterogeneous ring enhancement, such as a high-grade glioma, metastasis or lymphoma.
OBJECTIVE
We report a well-documented case of intracerebral schwannoma, presenting as a cystic and solid parietal mass, arising in a 20-year-old woman. Possible mechanisms underlying the histogenesis of this rare lesion are discussed.
METHODS
The clinical, radiological and pathological features are
