Objective Mini-case series highlighting diagnosis and management of patients at our facility presenting with cavernous malformations (CMs).

Background CMs affect roughly 0.2-0.4% of the population. Majority of the cases are sporadic, however, autosomal dominant familial presentation can occur manifesting as multiple CMs. Presentation varies from asymptomatic to symptomatic with seizures, focal neurologic deficits, headaches, and cerebral/extra-cerebral bleeds. Within the CNS, CMs can occur throughout the CNS, with the incidence of 80% being supratentorial, 15% present infratentorial, and 5% in the spinal cord. Treatment options for include observation, microsurgical resection, or stereotactic radio-surgery. We present a mini-case series of diagnosis and management of 4 patients with cavernous malformations.

Design/Methods Case Series

Results This series highlights four patients who presented to our facility within twelve months with diagnosis of CM. The average age of cases was 51, with the male to female ratio of 2:2. Three patients presented with headache and visual complaints, one presented with neck and multiple joint pain secondary to other etiologies. MRI showed the characteristic diagnostic “pop-corn” appearance in 3 cases (2 intracranial, one spinal). These patients were asymptomatic and conservatively managed. One patient demonstrated coexistence of two distinct cavernous malformations with multifocal micro-hemorrhages, potentially representing occult CMs. One patient had recurrent symptomatic intracerebral hemorrhage of unclear etiology with no radiographic or angiographic evidence. The cases with radiographically relevant CMs underwent conservative management, and the case with angiographically occult lesion required craniotomy for microsurgical resection of suspected cavernous malformation, which was later confirmed on biopsy.

Conclusions The series above highlights the common manifestations of intracranial or spinal cavernous malformation as variable presentations, manifesting frequently with headache and focal neurological deficits. Cavernous malformations have a wide range and can pose a diagnostic challenge as they can be angiographically silent and may warrant neurosurgical intervention.
