We report a patient who underwent gamma knife radiosurgery to treat recurrent meningioma after microsurgery and thereafter developed secondary malignancy adjacent to the original tumor. A 47-year-old woman had underwent resection of the olfactory groove meningioma. Then radiosurgery was done three times over 4 year period for the recurrent tumor. After 58 months from the initial radiosurgery, s...

Background: Olfactory groove meningiomas represent a difficult problem because of involvement of the arteries of the anterior circulation as well as the anterior visual pathways when increased in size. Objective: in my study I will discuss 12 patients with olfactory groove meningiomas regarding their clinical presentation, radiological appearance, surgical approach as well as their post operati...

Background Olfactory groove meningiomas remain surgically challenging. The common microsurgical approaches suffer from late exposure of the neurovascular structures. Conversely, the pterional approach has the advantage of early dissection of the posterior neurovascular complex. Methods We reviewed the records of patients treated for olfactory groove meningioma in our department between 1991 and...

A megameatus with intact prepuce (MIP) is an unusual variant of an anterior hypospadias that accounts for 3% of hypospadias repairs. It is characterized by a widely splayed coronal or subcoronal meatus, a deep glanular groove, a normally conformed prepuce, and no chordee. In this case, good cosmetic and functional outcomes, such as achievement of a straight urine stream and patient satisfaction...

There are various complications which have been described following excision of giant olfactory groove meningiomas and most of them have some pathophysiological basis and logic explaining their occurrence. Similarily, vascular insult to bilateral anterior cerebral arteries (ACA) could occur during surgery owing to its close proximity to the tumor. However, a 52 year old male who underwent compl...

Meningioma, a neoplasm derived from meningothelial cells, is one of the most common neoplasms in the central nervous system. Although certain types of meningiomas are associated with aggressive clinical behavior, majority of meningiomas appear to be benign. 2) Meningiomas are generally slowly growing tumors and produce neurological signs and symptoms either by compression of adjacent structures...

We report a case of glaucoma that resulted as a complication of superselective ophthalmic angiography in a 67-year-old man with a recurrent olfactory groove meningioma. Superselective angiography in the right ophthalmic artery was performed to confirm the orifice of the feeding arteries during preoperative embolization. Immediately after the fourth injection of contrast medium, the patient suff...
