TL;DR: The lipomatous lesion surrounded the internal carotid artery and trigeminal nerve and extended extracranially into the infratemporal region through a smoothly dilated foramen ovale.
Abstract: We present CT and MR features of a large intracranial lipoma located in the left sphenocavernosal region in a patient with a history of spinal intradural lipoma excision. The lipomatous lesion surrounded the internal carotid artery and trigeminal nerve and extended extracranially into the infratemporal region through a smoothly dilated foramen ovale.

TL;DR: The lipomas of the central nervous system are rare lesions of congenital origin and are located in the medial line and especially in corpus callosum and are involved in nervous and calcific tissues except for fatty tissues they can be mistaken for hamartomatous masses.
Abstract: The lipomas of the central nervous system are rare lesions of congenital origin and are located in the medial line and especially in corpus callosum. Intramedullary spinal lipomas can be seen in the life span of 30 years of age and most frequently coincide with initial puberty period. Magnetic resonance imaging and computerized tomography together with clinical trials are of crucial importance for diagnosis. The first case: A two-year-aged girl who had lipoma in quadrigeminal cistern and who suffered from encephalocraniocutaneous lipomatosis has been clinically studied. The fascial lipoma of the patient has been excised subtotally by the Plastic Surgeons; then the patient has underwent supracerebellar infratentorial operation where the intracranial lipoma has been excised by our team. The histopathology has been reported to be consisting of peripheric nerve tissue and calcification. The second case: A twenty-year-aged man with intramedullary lipoma localized between T1-T4 has been given our clinical trials. T1-T5 total laminectomy and subtotal excision were made for this patient. Due to the fact that the lipomas of central nervous system are rarely seen and are involved in nervous and calcific tissues except for fatty tissues they can be mistaken for hamartomatous masses. The total excision of the lipomas of central nervous system and especially the spinal intramedullary lipomas are quite difficult to be excised since they are tightly entangled with the neural tissue. So any attempt for total excision would be dangerous. Operation for decompression and biopsy is of primary concern.

TL;DR: Gross necropsy of euthanatized ducks revealed yellow intracranial masses in the brain of each, which were similar to those previously reported in other animals and humans.
Abstract: Four birds in a flock of 125 purebred Crested ducks (Anas platyrhynchos f. dom.) had cerebellar signs of unknown etiology. They had radiographically evident perforations of various sizes in the parieto- occipital calvaria. Gross necropsy of euthanatized ducks revealed yellow intracranial masses in the brain of each. Histologically, these masses were intracranial lipomas consisting of univacuolated fatty tissue separated into lobules by strands of connective tissue. The masses had caused serious deformation of the rostral part of the cerebellum, leading to a nearly complete flattening of cerebellar folia, and were interpreted as the cause for the central nervous clinical signs observed. These intracranial lipomas were similar to those previously reported in other animals and humans.

TL;DR: A case of lipoma of the sylvian fissure is reported without association with other congenital anomaly or vascular abnormality.
Abstract: Intracranial lipoma usually occurs at or near the midline, predominantly in the callosal cistern and very rarely in the sylvian fissure. We report a case of lipoma of the sylvian fissure without association with other congenital anomaly or vascular abnormality.
