A 5 year-old boy with a cerebellar gangliocytoma with a peripheral right facial paresis and ataxia is presented. His MRI showed a heterogenous, diffuse lesion, isointense on T1 and hyperintense on T2-weigthed sequences, involving the right cerebellar hemisphere with direct extension into the right facial nerve. The present case is the first description of a gangliocytoma with direct facial nerve invasion, as demonstrated for the facial nerve paresis and supported by MRI and surgical inspection.

<p>Bilateral temporal bone fractures are rare; accounting for 9% to 20% of cases of temporal bone fractures. Clinical manifestations include hearing loss, facial paralysis, CSF otorhinorrhea and dizziness. This is a case report of a patient who presented with bilateral temporal bone fractures. This is a report of a 23-yr-old male who sustained bilateral temporal bone fractures and presented 18 days later with complaints of watery discharge from left ear and nose, bilateral profound hearing loss and facial weakness on the right side. Pure tone audiometry revealed bilateral profound sensori-neural hearing loss. CT temporal bones &amp; MRI scans of brain were done to assess the extent of injuries. The patient underwent left CSF otorrhea repair, as the CSF leak was active and not responding to conservative management. One week later, the patient underwent right facial nerve decompression. The patient could not afford a cochlear implant (CI) in the right ear at the same sitting, however, implantation was advised as soon as possible because of the risk of cochlear ossification. The transcochlear approach was used to seal the CSF leak from the oval and round windows on the left side. The facial nerve was decompressed on the right side. The House-Brackmann grade improved from Grade V to grade III at last follow-up. Patients with bilateral temporal bone fractures require prompt assessment and management to decrease the risk of complications such as meningitis, permanent facial paralysis or hearing loss. </p>

Developmental venous anomaly (DVA) is a commonly encountered congenital abnormality of the venous drainage system. Spontaneous thrombosis of DVA is rare. We present a case of thrombosed brainstem DVA leading to venous infarction and oedema within the posterior fossa.A 49 year old, previously fit gentleman presented to the local hospital with a one day history of headache, slurred speech and incoordination. Examination demonstrated GCS of 13/15, cerebellar dysarthria, horizontal nystagmus to the left, mild right sided pyramidal weakness, right sided cerebellar ataxia and bilateral extensor plantars.CT venogram revealed a cerebellar DVA with thrombosis of one of the veins. There was surrounding venous infarction and oedema within the posterior fossa, causing compression of the fourth ventricle and dilatation of the lateral ventricles. MRI demonstrated extensive T2 change in the right cerebellar hemisphere, dorsal pons and right cerebral peduncle. No underlying thrombotic tendency was identified. He was treated successfully with intravenous heparin infusion. He improved over the next 3 weeks, and was discharged on warfarin with mild right sided ataxia and cerebellar dysarthria.Our case demonstrates that DVAs, generally considered as common insignificant anatomical variants, can uncommonly lead to significant complications.

Histopathological Analysis

Context: Primary central nervous system lymphomas (PCNSL) are a rare but very aggressive subtype of extranodal non-Hodgkin lymphomas. They represent only 4% of primary central nervous system lesions and are more common in patients with aggressive non-Hodgkin lymphomas, who are HIV positive. Moreover, PCNSL, usually presents as intraparenchymal supratentorial expansive lesions, while secondary CNS lymphomas tend to present as metastases in the leptomeninges. Although they are more common in immunocompromised patients, their incidence has increased with advancing age. Due to its uniqueness in findings, rarity, and severity of the case, we present an immunocompetent elderly patient with a primary lesion of the posterior fossa. Case report: A 85-year-old female was admitted to the emergency room with incoercible vomiting for 48 hours. Initial clinical examination showed dysmetry, and dysbasia. There was no clinical history compatible with immunosuppression. The initial magnetic resonance imaging revealed two non-enhancing contrast lesions in T1 and hyperintense in T2/Flair in the left caudate nucleus, and at the right cerebellar hemisphere near the fourth ventricle and a third parafalcine lesion with homogenous contrast-enhancing on T1 compatible with an incidental meningioma. PET scan, thyroid and breast ultrasonography, and abdominal MRI were done to rule out metastasis, and all results were negative. The histopathological analysis after a stereotactic biopsy performed on the caudate nucleus lesion confirmed the presence of primary central nervous system lymphoma. Conclusions: The pattern of PCNSL is changing due to aging. Knowing this is indispensable for the correct diagnosis and management.

AbstractThe cerebellum abnormalities may be hypoplastic, dysplastic, or hypoplastic. It is very rare that the cerebellar hemisphere is affected unilaterally in the posterior fossa abnormalities. The reason for this effect is mostly sequela. This pathology presents with neuromotor developmental abnormalities. In this presentation, isolated left cerebellar hypoplasia is described radiologically in a 21-month-old male patient with neuromotor development defects. Dysplastic appearance was noticeable in the observable part of the left cerebellar hemisphere and folia. The cerebellar vermis could not be shaped. The right cerebellar hemisphere, other posterior fossa formations, and supratentorial area were natural. In patients with neuromuscular abnormalities, the posterior fossa is applied with care. It should be remembered that cerebellar hypoplasia and dysplasia can be unilateral.

Abstract Schwannomas arise in the cells responsible for the mielinating the neurons distal to the Obersteiner-Redlich zone. Most of the intracranian Schwannomas are in the posterior fossa, developed from the VIIIth or Vth nerve stheath. The location on other cranian nerves is quite rare, only 6% of the orbital tumors being Schwannomas. We review the case of a 52 years old male patient, presenting for right eye exophthalmia and visual field deficit, diplopia due to VIth nerve paresis, and stubbing pain in the right eye, the MRI showing a tumor, located in the orbital apex displaced the globe forward and superiorly, and the optic nerve medially and superiorly. A modified lateral orbital approach was preferred. The choice of the orbitotomy allowed us to maintain the integrity of the lateral rim of the orbit without the need of a bony reconstruction at the end of the intervention, as it faced the anterior margin of the temporal muscle, covering it and not the skin over the zigomatic bone. The technical approach for orbital schwanomas should be tailored to reach the lesion through an esthetic incision and orbitotomy, immediately under the resected bone, with no need retracting the ocular globe or the vasculonervous elements in the orbit.

Background: Intracranial lipomas are sporadic congenital malformations. Previous studies have shown various brain anomalies related to intracranial lipomas, most of which are agenesis or dysgenesis of the adjacent structures. To the best of our knowledge, cortical dysplasia related to intracranial lipoma has yet to be reported. Case Report: We present a rare case of intracranial lipoma in the quadrigeminal and superior cerebellar cisterns with combined cerebellar cortical dysplasia. A 43-year-old female underwent brain MRI to identify possible causes of headache. We made a confident diagnosis based on MR findings using Dixon technique, which is a fat-water separation method based on chemical shift. We also identified unique combined abnormalities of the right cerebellar hemisphere near the cisternal lipoma that showed an abnormal vertical orientation of the cerebellar folia and disorganized parenchymal pattern. Conclusion: This case exhibits the rareness of the intracranial lipoma related cerebellar cortical dysplasia by reviewing relevant literature and also highlights the usefulness of Dixon techniques in daily clinical practice.
