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: MRI can precisely locate a small lesion that would be overlooked by CT scans and indicate that even subtotal removal can alleviate the symptoms of intracranial lipomas and that favorable results can be obtained.
Abstract: We encountered five cases of intracranial lipoma after introduction of MRI. They were located in the quadrigeminal plate, interpeduncular fossa, pineal region and two of them were found in the cerebellopontine angle, (although intracranial lipoma in this location has been reported to be extremely rare). MRI can precisely locate a small lesion that would be overlooked by CT scans. Operative treatment was performed in two symptomatic cases (CP angle and pineal lesions) and the tumors were subtotally resected. The symptoms of the patients disappeared postoperatively. This indicated that even subtotal removal can alleviate the symptoms of intracranial lipomas and that favorable results can be obtained.

TL;DR: A 37-year-old Turkish woman with an intracranial lipoma of the quadrigeminal region is reported, and the findings of imaging studies, including computed tomography (CT), magnetic resonance (MR), and a brief review of the literature are described.
Abstract: A 37-year-old Turkish woman with an intracranial lipoma of the quadrigeminal region is reported. Intracranial lipomas are extremely uncommon condition and generally occur in the midline areas, with an incidence of less than 0.1% of all intracranial tumours. Most lipomas were incidentally detected by autopsy or computed tomography (CT). The autopsy incidence of intracranial lipoma is 0.08% to 0.46%, while the incidence of CT finding is no more than 0.03% to 0.06%. Most intracranial lipomas are found incidentally during neuroradiological investigations. CT and MR examination usually lead to the diagnosis, because of the very low attenuation values of lipomas on CT and the short T1 and T2 on MR.We describe the findings of imaging studies, including computed tomography (CT), magnetic resonance (MR) imaging, along with a brief review of the literature.

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.
