Plexiform Neurofibroma

A plexiform neurofibroma is a benign (non-cancerous) tumor that grows along the length of a nerve, often involving multiple nerve branches. It’s most commonly associated with an inherited condition called neurofibromatosis type 1.

Signs & Symptoms

Symptoms can include a visible or palpable swelling along the affected area, pain, or nerve-related symptoms such as numbness or weakness if the tumor presses on surrounding structures.

Causes & Risk Factors

Plexiform neurofibromas are most often related to neurofibromatosis type 1, an inherited genetic condition. They are typically present from birth or early childhood, though they may not become noticeable until later.

Diagnosis

Diagnosis typically involves a physical exam and MRI imaging to define the extent of the tumor.

Treatment Options

Many plexiform neurofibromas are monitored over time, since they can be extensive and surgery carries its own risks. Surgery may be considered when a tumor is causing significant symptoms or affecting function.
