Summary Summary

Lhermitte-Duclos disease (LDD) is a very rare, benign (non-cancerous) brain tumor, called a dysplastic gangliocytoma of the cerebellum, that is characterized by abnormal development and enlargement of the cerebellum, and an increased intracranial pressure. LDD manifests most commonly in the third and fourth decades of life. Symptoms may include headache, nausea, cerebellar dysfunction, hydrocephalus, ataxia (problems with movement and coordination), and visual disturbances. Other features may include an enlarged brain (megalencephaly), hydromyelia, extra fingers or toes (polydactyly), partial gigantism, and/or a large tongue (macroglossia). Lhermitte-Duclos disease can occur as an isolated condition; it is also associated with a hereditary cancer syndrome called Cowden disease. Although the exact cause is unknown, mutations in the PTEN gene have been identified in some individuals with LDD.^[1]

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
