Intracerebral hemorrhage and hematoma in Behçet's disease: case report

Endovascular treatment of Behçet's disease-associated intracranial aneurysms: report of two cases and review of the literature

Behçet's disease (BD) is a well-known multisystem inflammatory disorder of unknown etiology. Aneurysms of the cerebral arteries are not commonly described in patients with BD. There are few cases of intracranial aneurysms with BD reported in the literature. In this study, we report endovascular treatment of BD-related ruptured intracranial aneurysms in two cases, and present a wide literature review of intracranial arterial aneurysms related to BD.

INTRODUCTION

Mostly venous (95% of all vascular complications), and less frequently arterial (2 to 7% of all cases), vascular complications are commonplace in Behçet's disease (23 to 64% of the patients, depending on the series). Arterial complications are stenosis, occlusions and especially severe due to their unpredictable rupture risk, aneurysms. Intracranial aneurysms associated with Behçet's disease are exceptional. Until now, only ten cases have been published.

EXEGESIS

We report the case of a 36-year-old patient of Armenian origin in whom the diagnosis of Behçet's disease was made after a subarachnoid hemorrhage caused by the rupture of a left superior cerebellar artery aneurysm. The endovascular treatment of the aneurysm was associated with an immunosuppressive treatment consisting of cyclophosphamide, corticoids and colchicine. Within a 6-month period of follow up the evolution has been favorable. This is the first published case report of Behçet's disease associated with an aneurysm of the posterior circulation treated endovascularly. A review of the literature is also included.

CONCLUSION

Intracranial aneurysms are an exceptional but nevertheless severe localization of vascular complications in Behçet's disease. As in all other arterial lesions, recurrences are frequent. The treatment involves surgical or endovascular treatment that should be associated with corticoids and immunosuppressive therapy. Colchicine is useful for the prevention of relapses.

Cerebrovascular complications of rheumatic disease

Cerebral ischemia and infarction, intracerebral hemorrhage, subarachnoid hemorrhage, cerebral venous thrombosis, and cerebral vasculitis are dreaded but largely uncommon complications of most rheumatic diseases. In some conditions, however, such as the antiphospholipid syndrome or Behcet's disease, stroke may be the presenting complaint. A format for approaching the patient and localizing the cerebrovascular lesion has been presented along with a summary of the specific rheumatologic diseases implicated for each stroke subtype.

Intracranial arterial aneurysm complicating Behçet's disease

Behçet's disease, a rare condition in central Europe but more common in Turkey where it was originally described, is characterized clinically by the presence of a diagnostic triad of oral and genital aphthous ulcers, meningitis, and relapsing iridocyclitis. Vascular lesions including arterial and venous occlusions, arterial aneurysms and varices are one of the common complications of Behçet's disease occur most commonly in the abdominal aorta, femoral arteries and pulmonary arteries. There have been only four reports of aneurysms of cerebral arteries in the literature. The authors describe a patient with Behçet's disease who suffered secondary subarachnoid hemorrhage due to a ruptured aneurysm of the anterior communicating artery 3 years after the initial diagnosis. This case report draws further attention to this rare entity in patients with Behçet's disease.

Surgical aspects of Behçet's disease

Behçet's disease is an uncommon condition that is managed primarily by medical therapy. Nevertheless, the widespread manifestations of the disease mean that surgeons from many different subspecialties may be involved in the care of patients. This is especially so for the treatment of life-threatening complications. For this reason the surgeon needs to consider Behçet's disease in the differential diagnosis of many conditions and to be aware of the general principles underlying the surgical care of affected patients.
