TL;DR: A 6-year-old girl with an unexplained headache was admitted to the Pediatric Outpatient Clinic with complaints of non-febrile seizure, which was a complex-partial type.
Abstract: Intracranial lipoma is a very rare condition, with an incidence of less than 0.1% of all intracranial tumors. They are mostly localized in the pericallosal region. Pericallosal lipoma is an extremely rare tumor of the central nervous system and rarely gives any symptoms. A 6-year-old girl with an unexplained headache was admitted to the Pediatric Outpatient Clinic with complaints of non-febrile seizure. Her seizure was a complex-partial type. Biochemical tests for seizure etiology did not reveal any specific cause. Electroencephalography (EEG) revealed typical epileptic activity. Magnetic resonance imaging (MRI) gave images of a mass approximately 1 cm in diameter in the vicinity of corpus callosum splenium. Her seizures were kept under control with carbamazepine (400 mg/day) and indicators of neuromotor development were found to be normal throughout 24-month period of follow up. Even though it is a rare condition, pericallosal lipoma should also be taken into account in the differential diagnosis of non-febrile seizures in children.

TL;DR: A rare case of midline craniofacial dysraphism with interhemispheric calcified lipoma together with subcutaneous lipoma and agenesis of the corpus callosum is presented.
Abstract: Frontonasal dysplasia (FND) or craniofacial dysraphism includes a variety of craniofacial defects. FNDs are rarely associated with intracranial lipoma. The majority of intracranial lipomas are incidentally identified on radiological examinations. They are commonly accompanied by other congenital intracranial malformations. Moreover, they are rarely associated with subcutaneous lipoma. We present a rare case of midline craniofacial dysraphism with interhemispheric calcified lipoma together with subcutaneous lipoma and agenesis of the corpus callosum.

TL;DR: A 60 year old female with a history of atrial fibrillation who was on warfarin therapy, presented to the emergency department with chief complaint of the most severe headache that she ever had, and had emergency computed tomography of the brain with suspicion of intracranial hemorrhage that revealed a lesion in fat dansity in the lateral ventricle and interhemispheric fissure.
Abstract: A 60 year old female, with a history of atrial fibrillation who was on warfarin therapy, presented to our emergency department with chief complaint of the most severe headache that she ever had. Her vital signs, systemic and neurological examinations were normal. She had emergency computed tomography (CT) of the brain with suspicion of intracranial hemorrhage that revealed a lesion in fat dansity in the lateral ventricle and interhemispheric fissure (Figure a). Her international normalized ratio was 3,2. She underwent cranial magnetic resonance imaging (MRI) that revealed a hyperintense lesion in T1 and T2 sequances in the lateral ventricles, pericallosal area and interhemispheric fissure that did not show contrast enhancement (Figure b and c). After the symptomatic relief by analgesics she was discharged from the emergency department for out-patient follow-up. Figure Image (a) shows cranial computed tomography. There is a homogenously hypodense lesion measuring 33 mm × 30 mm in the lateral and third ventricles with about −101 to −110 Hounsefield unit. Image (b) and (c) show magnetic resonance ... Intracranial lipomas are rare and benign congenital malformations accounting for 0,1% to 0,46% of all intracranial tumors.1 Since half of all cases are asymptomatic, they are usually an incidental finding during neuroimaging studies. Headache is the most common symptom in adults if it becomes symptomatic.2 The deep interhemispheric fissure, especially the corpus callosum, is the most common localization of intracranial lipomas.1 Intracranial lipomas are often associated with other malformations of the central nervous system, such as callosal agenesis or hypogenesis, spina bifida or a cranium bifidum.1,3 Noncontrast cranial CT and brain MRI allow definitive diagnosis. The appearance of the corpus callosum lipoma on the cranial CT scan is quite typical, with the low attenuation seen only in adipose tissue, which ranges from −40 to −100 hounsfield units.4,5 In the brain MRI the lesion presents characteristics of fatty tissue, with a hyperintense signal in both T1 and T2-weighted studies.6 Most lipomas are treated conservatively and rarely requires neurosurgical treatment because of their benign nature.1 Our patient did not have any accompanying lesion and was discharged to follow-up as an out-patient.

TL;DR: A patient with Pai syndrome who was followed up from birth up to the age of 8 years is reported, and she showed attention-deficit/hyperactivity disorder and her nasal airway was gradually obstructed by a residual intranasal polyp.
Abstract: Pai syndrome is a rare congenital disorder, and there are few reports about the long-term prognosis of mental development and surgical results. Here, we report a patient with Pai syndrome who was followed up from birth up to the age of 8 years. Additionally, we review 32 articles and discuss the long-term prognosis of Pai syndrome. In our case, an intracranial lipoma grew a little, but neither epilepsy nor intellectual disabilities occurred. However, she showed attention-deficit/hyperactivity disorder. Furthermore, her nasal airway was gradually obstructed by a residual intranasal polyp.

TL;DR: A hitherto unreported case is presented wherein a 2year old child had a 'cranial lipomeningocoel' or a 'nasal lipo-encephalocoel', which resulted in cosmetic recovery.
