BACKGROUND Intracranial osteomas are uncommon lesions that usually arise from the inner table of the cranium. There are few reports in the literature of intracranial osteomas with meninges attachment and without direct relation with the skull bone; these osteomas were mostly attached with dura. We report a rare osteoma with falx attachment. CASE A 64-year-old woman presented with a 3-month hi...

Intracranial cavernous angiomas are benign vascular malformations and can be divided into intra-axial and extra-axial lesions. Extra-axial cavernous angiomas are relatively rare and usually arise in relation to the dura mater and mimick meningiomas. We report a case of cavernous angioma that occurred in the falx cerebri of a 22-yr-old female patient with the special focus on neuroradiologic fin...

During regular dissection classes, we came across tripled falx cerebelli in a male cadaver. The main (middle) falx cerebelli was large and was attached to the internal occipital crest. It contained the occipital sinus. There were two smaller folds (right and left), one on either side of the falx cerebelli. There were two aberrant venous sinuses; each one connecting the ipsilateral sigmoid and t...

Here, we report the case of an incidental finding of lamellar calcification of the falx cerebri in a routine computed tomography scan of the head after an accidental trauma. This lamellar calcification led to the diagnosis of Gorlin-Goltz syndrome (GGS) in the patient and her daughter. Lamellar calcification of the falx cerebri is a pathognomonic feature of GGS. Our case report highlights the i...

A 43-year-old man arrived at the emergency department following a syncopal episode. Computed tomography and magnetic resonance images demonstrated a small interhemispheric, anterior parafalcine mass that mimicked a meningioma. Surgical excision and subsequent pathologic evaluation revealed an angioleiomyoma and the patient recovered without incident. Angioleiomyomas are classified as benign smo...

A 67-year-old man presented with consciousness disturbance and right hemiparesis. Computed tomography (CT) scan showed an intracerebral hematoma with two enhanced vascular lesions. Digital subtraction angiography revealed the dural arteriovenous fistula (dAVF) in the falx cerebri which was supplied by both bilateral middle meningeal arteries and left pericallosal artery and drained into both th...

Fig. 1.-A, Lateral skull radiograph shows a large midline calcified mass in corpus callosum region. B, CT with IV contrast enhancement shows midline density in falx region. C, Midsagittal T1-weighted (300 / 40) MR image shows a large mass of mixed signal intensity in falx cerebri region . Note that posterior half of body and splenium of corpus callosum have been replaced by tumor (straight arro...

Intracranial mature teratoma is a rare lesion in adults. Despite several intracranial mature teratomas had been reported not to be located at the midline region, no one was found to be within cerebral falx. Herein, we reported a 37-year-old female patient with an intracranial mature teratoma confined within frontal cerebral falx. Her main complaint was intermitted headache, which could not be r...
