Abstract
Opportunistic infections are on the rise because of an increasing number of patients with immunosuppression and their prolonged survival [1, 2]. Although invasive aspergillus sinusitis leading to a mycotic aneurysm of the intracavernous carotid artery is increasingly being reported, the magnetic resonance (MR) features supporting their mycotic origin are poorly known. A previous neuroradiological case report already extensively described the magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) findings of a fusiform aneurysm [3]. We now report the case of a saccular mycotic aneurysm involving the cavernous portion of the carotid artery, and discuss the imaging features supporting its mycotic origin.

Opportunistic infections are on the rise because of an increasing number of patients with immunosuppression and their prolonged survival [1, 2]
The diagnosis was made of a mycotic aneurysm of the intracavernous carotid artery resulting from local spread of invasive aspergillosis from the adjacent sphenoid sinus, secondary to an immunosuppressive status resulting from chemotherapy and longstanding systemic corticosteroid treatment
The saccularaneurysm described in this report did not appear to have any magnetic resonance imaging (MRI) or magnetic resonance angiography (MRA) features suggesting its mycotic origin, at least based on the con
Summary
Opportunistic infections are on the rise because of an increasing number of patients with immunosuppression and their prolonged survival [1, 2]. We report the case of a saccular mycotic aneurysm involving the cavernous portion of the carotid artery, and discuss the imaging features supporting its mycotic origin. The lesion in the cavernous sinus showed marked enhancement on contrast-enhanced T1WI and seemed to be inseparable from the carotid artery (Figure 1). Case Report A 67-year-old woman was admitted for retro-orbital and periorbital pain, increasing over 1 week and accompanied by progressive exophthalmia and palpebral ptosis on the left side. She was being treated for lung cancer metastasized to the liver and cerebellum. Brain MRI revealed an expansive lesion involving the left cavernous sinus (Figure 1), which proved to be a new.
