“…Extra-axial cavernous angiomas are uncommon, and the cavernous sinus is one location in this group. It is most common in women in their fifth decade of life and in Japanese people, being rarely multiple and hereditary (specially in Hispanic-American subjects) [1][2][3][4][5][6][7][8] . It is, in fact, a vascular malformation, which can behave like a real tumor when it grows up to the point to compress neighbor structures.…”

-Cavernous angiomas (cavernomas) of the cavernous sinus are uncommon, with only scattered reports in literature. Unlike their parenchymatous counterparts, they are intensely enhancing para-sellar masses, iso/hypointense in T1-and hyperintense in T2-weighted images. Differential diagnosis with parasellar meningiomas and schwannomas can be difficult. We report three cases of this condition, describing findings of diffusion-weighted imaging in this kind of lesion for the first time in literature.KEY WORDS: cavernous angioma, cavernous sinus, magnetic resonance imaging, computed tomography, angiography.Angioma cavernoso do seio cavernoso: achados aos exames de imagem RESUMO -Angiomas cavernosos (cavernomas) do seio cavernoso são lesões incomuns, com poucos relatos na literatura especializada. Ao contrário dos cavernomas parenquimatosos, são massas para-selares intensamente captantes, isointensas a hipointensas em T1 e hiperintensas em T2 nas imagens de ressonância magnética. O diagnóstico diferencial com meningiomas e schwannomas para-selares pode ser difícil. Relatamos os achados de imagem de três casos desta entidade, descrevendo os achados da ressonância magné-tica ponderada em difusão neste tipo de lesão pela primeira vez na literatura. PALAVRAS-CHAVE: angioma cavernoso, seio cavernoso, ressonância magnética, tomografia computadorizada, arteriografia.Cavernous angioma of the cavernous sinus is an extremely rare condition, and its differential diagnosis with tumors, namely para-sellar meningiomas and schwannomas, is often difficult. They are richly vascularized lesions, made up of a network of dilated, thin-walled vessels, and are responsible for less than one percent of all intracranial masses. The advent of magnetic resonance imaging (MRI) raised new diagnostic perspectives for this condition as we report in the study. METHODThis study was approved by the committee of Ethics of Clinica Radiologia Vila Rica, Brasilia DF, Brazil.Three female patients, with 42-years-old (patient 1), 45-years-old (patient 2) and 37-years-old (patient 3), are, respectively, presented with complaints of right-sided cranial nerves deficits (III nerve [patients 2 and 3], V1 nerve [patient 2] and VI nerve [patients 1 and 2]) and headaches. All of them underwent magnetic resonance imaging and cerebral digital subtraction angiography (DSA). Patients 2 and 3 were also submitted to computed tomography (CT). In all patients, MRI revealed well-delimited right para-sellar lesions, uniformly isointense in T1-weighted images and hyperintense in T2-, T2-and FLAIRweighted images, brightly enhancing after intra-vascular infusion of gadolinium. Diffusion-weighted sequence, performed in patient 3, revealed an isointense mass.

“…Although parenchymal cavernomas are easily resected in most cases, surgical excision of cavernous angiomas is often challenging because of abundant operative bleeding, due to the vascular nature of these lesions [3][4][5]7,8,10 . Predominantly vascular masses and mostly organized ones can be found 9 .…”

“…They are lesions circumscribed to the interior of the nervous parenchyma. 1,2 The most common sites of this lesion are the cerebral hemispheres, followed by the brainstem, the cavernous sinus, the basal ganglia and the thalamus. Considered a disease most commonly reported in females, its diagnosis is usually made after neurological manifestations related to the location of the angiomas.…”

Surgical Treatment of Cavernous Angiomas in the Pineal Gland – Case Report

et al. 2015

Pineal cavernous angioma is a vascular malformation that has a prevalence lower than 1%. The etiology is debated. It is believed that it is originated from an autosomal dominant inheritance or from radiotherapeutic treatment. Complete resection enables the cure and prevents complications of the natural evolution of the lesion, mainly hemorrhagic events. A female patient, with 67 years of age, presented mental confusion and visual acuity deficit, which evolved to periods of psychomotor agitation. A magnetic resonance imaging (MRI) scan of the head showed a lobulated mass lesion in the pineal region with hypersignal on T1 and hyposignal on the susceptibility weighted imaging (SWI) sequence. Hydrocephalus was also noticed. The patient underwent a microsurgery for complete lesion resection though a supracerebellar/supratentorial access. The anatomopathology revealed an arteriovenous malformation compatible with cavernous angioma. The pineal cavernous angioma is a rare malformation that should be considered in the differential diagnosis of expansive lesions of the pineal gland.
