Seeding in the walnut; Leptomeningeal spread of Breast Cancer

Breast cancer is the most common etiology of leptomeningeal carcinomatosis (LC), with or without brain parenchymal involvement. However, only 5% of patients with breast cancer develop leptomeningeal metastasis even in late clinical course. It can rarely be detected on bone scintigraphy. MRI is the modality of choice.
