Craniopharyngioma

When the tumor extends into the sella turcica, removal of the posterior planum sphenoidale and tuberculum sellae may be required to gain adequate intrasellar exposure.94 After removal of tumor, any defects communicating with the sphenoid sinus must be obliterated with fat and pericranial grafts.
Mucor and Mucormycosis
Published in Dongyou Liu, Handbook of Foodborne Diseases, 2018
Rhinocerebral mucormycosis (ROCM) commonly occurs in patients with diabetes mellitus, malignancies, and hematopoietic stem cell or solid organ transplants. Beginning at the paranasal sinuses, invading sporangiospores germinate and spread to the palate, sphenoid sinus, cavernous sinus, orbits, or brain, leading to general symptoms (headache, nausea, fever, and lethargy), facial symptoms (weakness, numbness, and pain), nasal symptoms (purulent drainage, stuffiness and rhinorrhea, epistaxis, and nasal hypoesthesia), ocular symptoms (periorbital or retro-orbital pain, diplopia and blurred vision, amaurosis, and acute vision loss), and central nervous system symptoms (convulsions, altered mental status, dizziness, and unsteady gait).
Emergency management of the complications of infective sinusitis
Published in S. Musheer Hussain, Paul White, Kim W Ah-See, Patrick Spielmann, Mary-Louise Montague, ENT Head & Neck Emergencies, 2018
Complications are due to spread of infection beyond the sphenoid sinus to include nearby intracranial structures and the orbit. These include the optic nerve and chiasm, cranial nerves (III, IV, V, VI), cavernous sinuses and pituitary gland. Complications include ophthalmoplegia, blindness, cranial nerve palsy, cerebral infarction, meningitis and intracranial infection.

The endoscopic direct transnasal sphenoidotomy (TNS) is one such surgery that is currently performed for sphenoid sinus disease and pituitary surgery. In TNS surgery, only the posterior portion of the superior turbinate, close to the sphenoid wall, is removed and an area of the anterior sphenoid sinus wall is cauterized (Har-El 2003). TNS has several advantages over its alternative, transethmoidal sphenoidotomy (TES), because it does not require the ethmoidectomy procedure, and thus avoids any of its subsequent side effects (Bahmanzadeh et al. 2015). Furthermore, TNS is minimally invasive, as it does not involve removing the uncinate process nor the basal lamella dissection (Schlosser and Bolger 2003). Therefore, TNS is a suitable alternative to other methods of sphenoid sinus surgery.
Pituitary metastasis from renal cell carcinoma: case report and review of the literature

Lin [8] reported a similar case of pituitary metastases from a renal cell carcinoma. In his case, transsphenoidal surgery revealed a vascular tumor that invaded the sellar floor and the normal pituitary gland. In another case, a trans-sphenoidal surgical approach was performed by Magnoli [9], and upon exposure of the sphenoid sinus extensive bone erosion was noted. Complete removal of all evident lesion was accomplished despite moderate tumor bleeding in his case. In a case of a pituitary metastasis of renal cell carcinoma reported by Weber [10], only a biopsy was possible because the surgical procedure was complicated by profuse tumor bleeding. These results were similar with our case. We reviewed some of the literature related to pituitary metastasis from renal cell carcinoma. The results summarized are shown in Table 3 [4, 8–25].
A Time Bomb Defused, In Time! A Traumatic Optic Neuropathy To Be Wary Of

Aneurysm refers to persistent pathologic dilatation of the vessel wall. It may be a true or a pseudoaneurysm. In a true aneurysm, the vessel wall is intact whereas in a pseudoaneurysm the vessel is partially transected with a discontinuity in the vessel wall. Traumatic aneurysms of intracranial carotid artery (ICA) and its branches are rare lesions with an estimated incidence of 0.15% and 0.40% of all intracranial aneurysms.1 These aneurysms can cause complications due to delayed rupture or mass effect on the adjacent cranial nerves. Associated injury to the ophthalmic artery can cause immediate blindness and the downward protrusion of the mass into the thin bone of ethmoid and/or sphenoid sinus can lead to mass effect on the adjacent structures like optic nerve and the oculomotor nerves causing vision loss and ophthalmoplegia which may be associated with massive epistaxis. We report one such case of delayed presentation of pseudoaneurysm of ICA who came to us for evaluation of blindness and ophthalmoparesis. Most of the traumatic pseudoaneurysm of internal carotid artery (TPICA) are diagnosed in the neurosurgical or otolaryngology clinics. The authors share an interesting case of TPICA presenting to an ophthalmologist with an orbital apex syndrome.
