“…The latter is thought to result from direct infiltration of the arterial wall by inflammatory cells (8). Based on these reports, we speculate that both the pneumococcal meningitis and intracavernous carotid artery aneurysm detected in our patient were caused by sphenoid sinusitis.…”

A 61-year-old Japanese woman presented with a headache and appetite loss lasting for nine days and was admitted to our hospital, where she was diagnosed with pneumococcal meningitis associated with acute sphenoid sinusitis. While the administration of meropenem and dexamethasone ameliorated the meningitis, right third and sixth nerve palsy suddenly developed 10 days after admission. CT angiography subsequently demonstrated an aneurysm in the cavernous portion of the right internal carotid artery. This is the first reported case of sphenoid sinusitis simultaneously complicated by both pneumococcal meningitis and an infectious aneurysm in the intracavernous carotid artery.

“…Up to now, few studies have illustrated the pathological features of ICIA. Sugie et al [ 40 ] performed an autopsy study of ICIA, in which histological examination showed discontinuous vessel wall of the infected ICA, and inflammatory infiltration in the adventitia and adjacent tissues. Moreover, another autopsy study showed obvious neutrophil infiltration of the adventitia and media with reactive intimal proliferation, suggesting an associated subacute/chronic inflammatory focal angiitis that may weaken the vessel wall and promote aneurysmal formation.…”

Rationale: Intracavernous infectious aneurysm (ICIA), represents a rare entity that is always described in the form of case reports in the literature. The coexistence of ICIA and cavernous sinus thrombosis (CST) is extremely rare and poorly understood. Patient concerns: A 53-year-old female patient presented to our hospital with headache, nausea and fatigue for 3 weeks. She complained of blurry vision and drooping eyelids before admission. Neurological examination revealed bilateral decreased visual acuity, limitation of extraocular movements and decreased sensation of forehead. Brain magnetic resonance imaging (MRI) showed mixed signal intensities in both cavernous sinuses and expansion of right superior ophthalmic vein, suggesting the formation of CST. One month later, computed tomography angiography (CTA) confirmed a large aneurysm was attached to the left intracavernous carotid artery (ICCA). Diagnoese: This patient was diagnosed with ICIA and CST. Interventions: She was administered with intravenous meropenem and vancomycin and subcutaneous injection of low molecular heparin for 4 weeks. Outcomes: One month later, her extraocular movement had significantly improved, without ptosis and conjunctival congestion. At 1-year follow-up, her ophthalmoplegia fully recovered. Fortunately, such large aneurysm did not rupture in spite of slight broadening. Lessons: The coexistence of ICIA and CST is extremely rare. Contiguous infection from adjacent tissues is the foremost cause of ICIA. A repeated angiographic examination is recommended under enough anti-infective treatment due to the characteristics of rapid emergence and fast growth of infectious aneurysms.
