Cavernous angioma, cavernoma, cavernous hemangioma, also called cerebral cavernous malformation (when present in the brain), are benign vascular malformations, usually intraparenchymal; however, a few reported cases are in the extra-axial location—as middle cranial fossa, near the cavernous sinuses, and in the cerebellopontine angle—and are rarely reported as dura-based convexity lesion resembling meningioma. We report a giant dura-based, convexity, a cerebral cavernous malformation. We wish to notify the case as occurring at a rare location and a large-sized cerebral cavernous malformation. A case of young female presented with a long-standing history of headache. Computed tomography scan and magnetic resonance imagings (MRIs) suggested right occipital dura-based large mass lesion of approximately 5 cm in diameter. The lesion was excised and pathology studies confirmed the diagnosis of a cerebral cavernous malformation. A follow-up MRI confirmed total resection of the lesion and the patient had a smooth postoperative recovery.

Meningiomas are the most common brain tumors in adults and are often incidentally detected on imaging studies. Most often diagnostic confidence is high on the basis of imaging findings. Meningiomas may demonstrate atypical features such as cysts, hemorrhage, or metaplastic changes that can be misleading. Several other neoplastic and granulomatous inflammatory conditions may mimic meningiomas. Differentiating these lesions from meningiomas is important because treatment strategies and prognoses differ. We will review and discuss the typical and atypical imaging features of meningiomas and how to differentiate meningioma from its mimics.Learning Objectives: After reading the review and completing the accompanying CME questions, the reader will be able to do the following: describe the typical and less common imaging findings of meningiomas, diagnose meningiomas presenting in uncommon locations, and differentiate meningiomas from mimics.

Cavernous angiomas (CAs) are benign vascular malformations predominantly seen in the brain parenchyma and therefore referred to as intra-axial. Extra-axial dural-based cavernous angiomas, on the other hand, are rare vascular lesions found outside of the brain parenchyma. They occur in the middle fossa and may be easily misdiagnosed as meningiomas due to their extra-axial location. In addition, CAs that are located outside the middle fossa, such as in the convexity, have a better prognosis since they are more surgically accessible. Surgical resection is the main treatment of choice in CAs. However, other options, such as embolization and radiotherapy, may also be considered therapeutic choices or additive treatment options. The pathogenesis of CA and the involvement of other factors (genetics or environmental factors) are still unknown and require further investigation. We are presenting a young man who presented for evaluation of seizure-like events without any family history of neurologic conditions. The physical examination was unremarkable except for a slightly antalgic gait. Imaging studies showed an extra-axial left tentorial mass suggestive of a meningioma, hemangiopericytoma, or other extra-axial lesions. The lesion was resected where its vascular nature was mentioned initially, and the histology proved the diagnosis of cavernous angioma. Here we give an overview of the known pathogenesis, causes, clinical features, and diagnostic and therapeutic options in CA. Better knowledge about CA, its causes, clinical features, and treatment options would help clinicians in early diagnosis and patient management.
