Orbital lymphangioma is an intra-orbital, nonencapsulated, congenital vascular tumor with a propensity for recurrent hemorrhage. It is a common vascular tumor in children below 10 years of age. Adult orbital intraconal lymphangiomas are very rare. The authors present a case of 68-year-old male patient presented with left eye symptoms of decreased vision, proptosis, restricted eye movement, and diplopia. The symptoms started following a trauma to the left eye 6 months back. Contrast magnetic resonance imaging scan showed a contrast enhancing well-defined 2.2 cm × 1.8 cm × 1.8 cm fairly rounded, slightly lobulated intraconal tumor in the retrobulbar region inferior to optic nerve. Patient underwent the left fronto-temporo-orbito-zygomatic (FTOZ) craniotomy. The tumor was moderately vascular, firm in consistency with lobulated surface. Few foci of hemorrhages were seen. Near total excision of the tumor was done. Histopathology and immunohistochemistry confirmed the diagnosis of orbital lymphangioma. Although rare, intraconal orbital lymphangioma should be kept in the differential diagnosis of orbital tumors presenting in adult patients following a trauma. It can radiologically mimic other intraorbital tumors. It is a surgical challenge and FTOZ craniotomy provides direct access to the orbital intraconal compartment.

However, it can cause vision loss by compression of the optic nerve at the optic foramen in infrequent circumstances. We report a rare case with an unusual manifestation of ptosis, proptosis, lateral rectus palsy, and acute vision loss in the right eye. Magnetic resonance imaging was suggestive of cysticercal cyst. Emergency optic nerve decompression with cyst excision was done. Treatment of choice for extraocular muscle cysticercosis presenting with restriction of eyeball movements is mainly medical, consisting of albendazole and steroids. However, as this lesion rarely causes vision loss, indications of surgical decompression of optic nerve are not well defined. We recommend that early surgical management should be done along with medical treatment in cases of vision loss caused by extraocular muscle cysticercosis.

More specifically, 30% of all newly diagnosed cases of NHL in the United States (US) are of diffuse large B-cell lymphoma (DLBCL) type, making it the most prevalent form of NHL in the US. Arising from either nodal or extra-nodal lymphatic tissue origin, DLBCL is an aggressive tumor which is fatal if left untreated. Primary central nervous system lymphoma is rare; however, when diagnosed, it presents as a DLBCL in 90% of patients. Herein, we present an elderly male complaining initially of acute epigastric pain but soon afterward developed acute spinal cord compressive symptoms; subsequently, it was found to be caused by a primary DLBCL diagnosed in the thoracic spinal cord. This case report presents a rare condition with unexpected initial presentation, and we attempt to illustrate the importance of early detection and treatment of DLBCL in attaining more favorable prognostic and survival rates among patients. Written consent was obtained from the patient after reading a written summary of the case report. This consent was checked and approved from the Scientific Board of the University of Aleppo.

We present a 66-year-old patient with right-sided hemiatrophy and paresis presenting with an adult-onset seizure disorder. Her seizure was satisfactorily controlled with a single-therapy antiseizure drug. Congenital brain lesions should be part of the differential diagnoses in patients with epilepsy who have body asymmetry dated back to childhood.

These cysts are usually located in the middle cranial fossa. However, they are also denoted in other regions. Arachnoid cysts are mostly asymptomatic and diagnosed incidentally. Spontaneous regression of arachnoid cysts in different anatomical regions of the brain has been reported in the literature. However, to the best of our knowledge, this is the first case reporting an unusual spontaneous regression of arachnoid cyst in the pineal region in a 3-year-old child presented to our hospital with hydrocephalus without alarming signs and was treated conservatively as the patient was stable, and the cyst showed spontaneous regression. A comprehensive review of the literature regarding spontaneous regression of arachnoid cysts has been collected and discussed in this article. check details Copyright © 2020 Asian Journal of Neurosurgery.We describe a patient with multiple cranial dural arteriovenous fistulas (DAVFs) presenting with thalamic dementia. A 52-year-old man experienced progressive dementia and behavioral change for 1 month. Cranial computed tomography scan and magnetic resonance imaging (MRI) showed bilateral thalamic edema with subsequent hemorrhagic transformation. Cerebral angiography demonstrated multiple cranial DAVFs at the straight sinus and posterior part of the superior sagittal sinus. The symptomatic fistula was the straight sinus DAVF, Cognard Type II a + b, supplied by meningeal branches of the left superior cerebellar artery, the left ascending pharyngeal artery originating from the left occipital artery, and multiple tiny branches of the left occipital artery with retrograde venous drainage into the straight sinus and vein of Galen. In addition, there was probable thrombosis at the middle part of the straight sinus associated with anatomical variation of the dural venous sinuses at the torcular herophili. The patient underwent successfully endovascular treatments in a two-staged embolization using liquid embolic materials.
