cavernous haemangioma and Kaposi's sarcoma," American Journal of Surgical Pathology, vol.
Isolated SOVT is extremely rare, and the association of SOVT and
cavernous sinus thrombosis is more commonly seen [2].
Trigeminal schwannomas in the
cavernous sinus usually arise in the Meckel's cave and demonstrate secondary anterior extension (2).
Its primary symptoms include idiopathic granulomatous infammation of the
cavernous sinus, superior orbital fissure, and/or the apex of the orbit (3,4).
Intramedullary
Cavernous Angiomas of the Spinal Cord.
The patient was finally diagnosed with intracranial space-occupying lesions and
cavernous hemangioma.
Blood samples were sent to the laboratory for
cavernous blood gases, full blood count, and renal function tests.
The acute development of a
cavernous sinus syndrome with associated cranial nerve deficits in conjunction with an aneurysm entirely encased within a neoplastic lesion supports the diagnosis of an acutely enlarging pseudoaneurysm, and we describe the first reported use of endovascular flow diversion therapy in such a setting.
(2,4) The types of hemangiomas include capillary type,
cavernous type, and mixed type.
Cavernous degeneration of the optic nerve (also known as Schnabel
cavernous degeneration) is considered a morphologic variant of ION.
An orbital MRI performed later demonstrated the presence of a dilated left superior ophthalmic vein (Figure 2) and suggested a carotid
cavernous fistula (CCF) as the provisional diagnosis.
Allen and Enzinger classified them into three types based on histopathological features into capillary (50%),
cavernous (29%), and mixed (21%).
