Lhermitte Duclos syndrome Radiology

MRI. Marked enlargement of the right cerebellar hemisphere without a focal mass or cystic change. The hemisphere is isointense on T1 and hyperintense on T2 weighted images with no abnormal enhancement. There is marked positive mass effect in the posterior fossa which is enlarged A large, heterogeneous, non enhancing and non-calcified right cerebellar mass compresses and distorts the fourth ventricle with resultant dilatation of the third and lateral ventricles and tonsillar herniation.There is no appreciable contrast enhancement following administration of contrast Lhermitte Duclos disease (Dysplastic cerebellar gangliocytoma). TEACHING POINTS: Lhermitte Duclos disease or Dysplastic cerebellar gangliocytoma is a rare low-grade WHO grade I tumour of the cerebellum. It is usually seen in young individuals with symptoms ranging from mild headache to cerebellar signs. CT : CT is of limited value. It may show a non-specific hypodense mass without appreciable enhancement Eighty percent of patients with Cowden syndrome have germline mutations in the PTEN gene at locus 10q23.2, which has been identified as the major susceptibility gene for Cowden syndrome (, 10 11). Most patients with Lhermitte-Duclos disease appear to have a germline loss of one PTEN allele and go on to lose the remaining PTEN allele at some point, thereby allowing abnormal growth of the granule cells ( , 11 , , 12 ) In summary, Lhermitte-Duclos disease, or dysplastic gangliocytoma of the cerebellum, is a pathognomonic radiologic entity, the diagnosis of which should remain not only in the bailiwick of neuroimaging specialists but general radiologists as well

COLD syndrome is the acronym for the concurrent diagnosis of Cowden syndrome and Lhermitte-Duclos disease. It has been suggested that COLD syndrome should be considered a phakomatosis 1 The Teaching Point: Dysplastic gangliocytoma of the cerebellum, also known as Lhermitte-Duclos disease, is an uncommon hamartomatous tumor associated with Cowden syndrome that typically grows unilaterally in one of the cerebellar hemispheres. On MRI, Lhermitte-Duclos is characterized as a nonenhancing cerebellar mass with a distinct, striated appearance thyroid cancer: develops in 5% of those with the syndrome, usually follicular; CNS: dysplastic cerebellar gangliocytoma, occurs when in association with Lhermitte-Duclos disease (LDD) Syndromic associations. Cowden syndrome is part of a group of disease known as PTEN-related diseases, which also includes: Lhermitte-Duclos disease (LDD When associated with anomalies of the kidneys, liver and/or eyes then the term Joubert syndrome and related disorders (JSRD) is used. Epidemiology. The prevalence of Joubert syndrome is approximately 1 in 100,000.

In 1920, Lhermitte and Duclos described a rare dysplastic gangliocytoma (Lhermitte-Duclos disease). The nature of LDD and its pathogenesis, as well as the exact genetic alterations, are unknown. In view of the debate whether LDD represents a neoplastic, malformative, or harmartomatous lesion, we examined two patients by use of different imaging techniques Lhermitte-Duclos disease, also known as dysplastic gangliocytoma of the cerebellum, presents as a focal or diffuse cerebellar hemisphere mass with striation on MR. Symmetric thickening of the folia is a characteristic feature Lhermitte-Duclos disease, also called dysplastic cerebellar gangliocytoma, manifests in young individuals. Most patients' symptoms stem from increased intracranial pressure and hydrocephalus. A slowly progressive cerebellar syndrome, megalocephaly and mental retardation are less common clinical features. It is considered a hamartomatous lesion,.

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. The possibility of preneoplastic states in Cowden syndrome stresses the importance of a thorough screening when Lhermitte-Duclos disease is diagnosed.

Based on these findings, our diagnosis was dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease). 3. Discussion. Mutation of the tumor suppressor gene PTEN, a gene located on the long arm of chromosome 10 (10q23), is the genetic alteration that characterizes Cowden syndrome, also called multiple hamartoma syndrome [1] [2] [3] Abstract. Lhermitte-Duclos disease or dysplastic gangliocytoma of the cerebellum, is a rare cerebellar lesion, which can cause mass effects in the posterior fossa. It may occur sporadically, or in association with Cowden syndrome. Cowden syndrome or multiple hamartoma-neoplasia syndrome, is an uncommon autosomal dominant condition characterized. Lhermitte-Duclos disease is a rare entity that was first reported in 1920. 1 Histologically, it has been termed a dysplastic cerebellar gan-gliocytoma. 1-3 This is because the fundamental nature of the lesion and, particularly, its pathogenesis remain unknown.

Cancer risk and Lhermitte-Duclos disease (LDD) risk estimates for Cowden syndrome (CS) are broad and based on a small number of patients. Risk estimates are vital to the development of diagnostic criteria, genetic counseling, and cancer surveillance. To further elaborate and estimate the risks associated with CS, a large cohort of patients was evaluated Lhermitte-Duclos disease (LDD) is a benign neoplasm of posterior fossa, involving cerebellum. It is also known as dysplastic cerebellar gangliocytoma. It is not a true neoplasm but a hamartoma. It can be either isolated finding or associated with Cowden disease (multiple hamartoma syndrome). Lhermitte-Duclos disease typically presents in young.
