Rare case of giant pediatric cavernous angioma of the temporal lobe: A case report and review of the literature

Giant cavernous malformations of the central nervous system are quite rare. They are more common in children and may be misdiagnosed as other intracranial neoplasms. Here, we presented a very rare giant cavernous angioma mimicking a neoplastic temporal lobe lesion in an 18-month-old male. An 18-month-old male presented with two initial seizures. Although the clinical examination was normal, the computed tomography (CT) scan showed a large left temporal mass (66 mm diameter) exerting significant mass effect and midline shift. The brain magnetic resonance (MR) imaging demonstrated a large left temporal heterogeneously enhancing lesion with significant perilesional edema and mass effect. The patient underwent gross total removal of the lesion that proved to be an intracranial cavernous angioma. Postoperatively, he did well, exhibiting no residual neurological deficit, and has remained lesion and seizure-free. This and 12 other cases in the literature focus on intracranial cavernous angiomas that could have been readily misdiagnosed as tumors. It confirms why obtaining appropriate preoperative MR and CT studies, followed by surgical intervention, is essential to confirm the correct underlying pathology and appropriately and optimally treat the patient.
