The first clinically diagnosed and successfully operated case of a symptomatic lipoma involving the cerebral cortex is reported. The patient presented with severe headaches and recurring focal seizures with secondary generalization. Computer tomography scan and magnetic resonance imaging suggested a left frontoparietal lipoma. After undergoing a craniotomy and tumor excision, the patient has shown resolution of headaches and seizures at 1-year follow-up. Lipomas of the cerebral cortex should be excised if symptomatic and accessible.

Lipoma of the corpus callosum is a rare congenital intracranial tumor. Although only 153 cases had been reported as of March 1992, the incidence of this tumor is underestimated (some cases are unpublished and others are asymptomatic). Three cases of lipoma of the corpus callosum diagnosed in children are reported herein. These tumors may be either discovered fortuitously in an asymptomatic patient or responsible for manifestations of which the most common are seizures, headache, and mental disorders. Diagnosis rests on imaging techniques. The main investigation is computed tomography which discloses a mass composed of fat, with or without peripheral calcifications, and also identifies any other malformations such as dysgenesis of the corpus callosum.

A 13-year-old girl was admitted with headache of sudden onset. Neurological examination did not reveal any abnormalities on admission. Her growth and development were normal. CT scan showed a high density mass in the pineal region without contrast enhancement. It was a spontaneously thrombosed aneurysm of the vein of Galen associated with thrombosis of the straight and the transverse sinuses on MRI. Moreover, there were an interhemispheric lipoma and a right temporal arachnoid cyst. The superior sagittal, bilateral transverse, sigmoid and straight sinuses were not opacified but unusual pathways of various venous channels were demonstrated on angiograms. Persistent fetal drainage remained as the collateral venous pathways such as the ventral diencephalic and striate veins and the paired longitudinal head sinuses. There were two types of unusual deep venous pathways. The left internal cerebral vein drained into the left ventral diencephalic vein. The left ventral diencephalic vein drained through the left lateral mesencephalic and ponto-medullary veins into the spinal venous plexi. The dilated striate veins drained into the deep middle cerebral veins through the cerebral parenchyma. Mainly, there were three types of superficial venous pathways. The paired longitudinal head sinuses drained into the emissary veins at the ethmoid sinus in retrograde fashion, and finally into the nasal mucosa. The superficial cerebral veins drained into the cavernous sinus which communicated with the nasal mucosa and the pterygoid plexi. The veins of the posterior fossa drained into the occipital emissary veins. After being admitted, the patient had remarkable nasal bleeding which was difficult to stop. This symptom seemed to be related to the collateral venous drainage to the nasal mucosa shown on angiograms. Finally, she became completely asymptomatic three weeks after admission.

Two single men, one with compressive spondylitic cervical myelopathy and another with tethered cord and intraspinal lipoma, experienced severe paroxysmal ice pick-like pains, solely referred to the neck in the first and to the groin and genitalia in the second, that were precipitated by masturbation and masturbatory orgasms. Continuous, but less intense, background pain was reported by both patients over the same anatomic areas. Neither had intracranial lesions, epilepsy, or suffered from migraine. Recently, extratrigeminal ice pick status was reported in this journal. These two unusual cases represent examples of extracephalic ice pick-like pain triggered by sexual activity, in the absence of orgasmic cephalgia.

A case of intracranial lipoma located in the interpeduncular fossa of a young woman is presented. Since the patient suffers only nonspecific headache, no treatment was performed. To our knowledge this is the only which was demonstrated by magnetic resonance images (MRI) in the English language literature.

Three children with complete or partial callosal aplasia and intracranial lipoma in the corpus callosum region were investigated. Two lipomas were tubulonodular; one replaced the entire corpus callosum structure. Accompanying anomalies affected the cingulate gyrus, septum pellucidum, and choroid plexus. In one case, diagnosis was made in utero in the 25th gestational week by ultrasonography; in the second case it was made on the first day of life, also by screening ultrasonography. Two children had mild spastic distal diparesis; one complained of chronic headache. Electroencephalography showed no abnormalities; epilepsy anamnesis was negative. Somatosensory and visual evoked potentials showed prolonged conduction in two cases. Surgery was not indicated. Because of the risk of developing epileptic seizures, regular electroencephalographic follow-up investigations are essential.

Lipoma of the cerebellopontine angle is a very rare tumor. We report the case of a 14-years-old female, with left side deafness during three years, associated with headache. CT scan showed an hypodense mass, without enhancement at the cerebellopontine angle. The patient was treated surgically by left retrosigmoid approach. The lesion involved the eighth and seventh cranial nerves and only a partial removal was performed. The postoperative course was uneventful. She had no more headache; the deafness of the left side remained unchanged. Asymptomatic lipoma of the cerebellopontine angle can be treated conservatively, although those with progressive symptoms should be treated surgically, with total or partial remove based on their neurovascular involvement.

Trigeminal neuralgia and cerebellopontine-angle lipomas are very rare in children. We describe the history and findings of an 8-year-old boy with right trigeminal neuralgia and a lipoma detected by magnetic resonance imaging at the level of the root-entry zone of the right seventh cranial nerve. We propose a possible mechanism of infiltration of the trigeminal rootlets by the lipoma.

A retrospective study was performed in order to evaluate the frequency of abnormalities found by computed tomography (CT) scan of the head in 78 patients with migraine or tension-type headache. In the present study CT scan was normal in 61.5% of the patients with migraine or tension-type headache. A number of abnormalities were encountered in more than one third of the patients studied, including inflammatory sinus disease (19.2%), cysticercosis (3.9%), unruptured cerebral aneurysm (2.6%), basilar impression (2.6%), intracranial lipoma (2.6%), arachnoid cyst (2.6%), empty sella (2.6%), intracranial neoplasm (2.6%), and others (2.6%). None of these lesions were symptomatic or responsible by the headache picture, therefore, considered incidental findings. In conclusion, the fortuitous encounter of some abnormalities on CT scan of the head is often higher than what we could predict in patients suffering migraine or tension-type headache. We briefly discuss clinical, epidemiologic, and practical management of some of the abnormalities detected by CT scan as well as the indication to request a neuroimaging investigation.

Interpeduncular lipoma (IPL) is a very rare benign intracranial lesion. Non-invasive diagnosis of this condition is important, as these lesions are usually asymptomatic and are found incidentally. We describe a rare case of IPL in a 35-year-old woman presenting with headache of long duration and a recent increase in severity and frequency of headache. There was no neurological abnormality on clinical examination. MR imaging demonstrated a homogeneous lobulated T1-hyperintense and T2-hypointense lesion in interpeduncular fossa. A T1-weighted fat suppression sequence with chemical shift method confirmed the fatty nature of the lesion. The patient was managed conservatively.
