We present an unusual case of a frontal sinus mucocele with intracranial and intraorbital extension. We also discuss the diagnosis and current management principles of this unusual lesion.

UNLABELLED Malignant eccrine spiradenomas are exceedingly rare tumours. They are aggressive tumours normally arising in long-standing benign eccrine spiradenomas. We present a case of malignant eccrine spiradenoma of the right side of the face with direct intracranial extension without distant metastasis. A 48 years old woman presented with a large exophytic tumour on the right side of her face...

OBJECTIVE To determine the imaging and demographic characteristics of intracranial haemorrhages, which are subsequently found to be due to an underlying intracranial vascular malformation (IVM). METHODS We compared the demographic and brain imaging characteristics of adults presenting with intracranial haemorrhage, subsequently found to be due to a brain arteriovenous malformation (BAVM), dur...

Juvenile nasopharyngeal angiofibroma (JNA) is a histologically benign, highly vascular tumor of the nasopharynx, which commonly presents in male teenagers. Morbidity from JNA is due to progressive obstruction of nasal respiration, bleeding, obstruction, invasion of paranasal sinuses, and in advanced cases due to intracranial extension. Intraorbital extension of tumor can lead to vision loss or ...

PURPOSE To present a rare presentation of optic nerve glioma (ONG) with total intraocular extension. METHODS A 44-year-old man with a history of loss of vision since childhood and recent development of progressive disfiguring proptosis was referred. RESULTS The vision in the affected eye was no light perception, and a proptosis of about 2-3 mm was present. Computed tomography and Magnetic R...

Complications of paranasal sinus infection most often involve the orbit and periorbita. Because intracranial extension of sinus disease is infrequently seen today, the clinician may be unfamiliar with the evaluation and management of this potentially devastating complication. Despite recent advances in treatment and diagnostic imaging, intracranial extension is often not recognized early enough...

In a prospective study using CT as the initial means of radiologic evaluation in 262 patients with proved nasopharyngeal carcinoma, the paranasopharyngeal space was found to be the most commonly involved region (84.4%), both uni- and bilaterally. Unilateral involvement was found in 44.3% of patients (116/262) and bilateral involvement in 40.1% (105/262). The other structures or regions that wer...

Cases Traumatic intracranial aneurysm following blunt head injury is uncommon but can be induced by extension of skull base fracture and causes unexpected hemorrhagic complications. We present two cases of traumatic intracranial aneurysm in the paraclinoid area that was revealed by delayed massive epistaxis. Lack of initial neurological deficits omitted screening for cerebrovascular injury. O...

The use of endoluminal revascularization has revolutionized many areas of medicine, including cardiology and vascular surgery. More recently, the application of balloons and stents to the intracranial circulation has been made possible by rapid and constant developments in device technology. These advances have fostered the use of stenting for the treatment of various intracranial disorders, in...

Meningioma, craniopharyngeoma and glioma are mainly intracranial lesions. Nevertheless, in rare cases these entities may occur solely as extracranial lesions that may present as intranasal/sinusoidal masses, with headaches and nasal obstruction. We present three cases of common intracranial tumors, with purely extracranial extension. The three described cases demonstrate, that preoperative MRI ...
