Therefore, the case that is presented in this report is unique. An 18-year-old woman was admitted to our department because she presented with morning stiffness, joint deformation, and swelling in both hands. [ncbi.nlm.nih.gov]

Cataracts are present in 76% cases and are generally seen as early as 5-6 years of age. [1] Seizures are encountered in 40-50% cases, and can be the presenting problem in some cases. A sensory-motor neuropathy has also been documented. [neurologyindia.com]

• Soft Tissue Swelling

  Computed tomography of the right hand showed soft tissue swelling on multiple small joints, including metacarpophalangeal and proximal interphalangeal joints, but without obvious bone destruction. [ncbi.nlm.nih.gov]

  A single soft tissue swelling was present on the Achilles tendon. CT scan showed hypodensity in bilateral cerebellar white matter and brainstem. [neurologyindia.com]

  (a and b) multiple firm to hard, mobile from side to side, non tender swellings of size varying from 6 4 cm to 3 3 cm present over posterior aspect of both ankles, attached to tendoachilles; (c) plain lateral radiographs of both ankles shows soft tissue [idoj.in]

  The cholesterol-to-cholestanol ratio is said to be a better indicator of disease than the cholestanol concentration alone. [24] The radiographs revealed fusiform soft tissue swellings, which were found as hyperintense signals in those regions in the MRI [jdrntruhs.org]

• Aspiration

  We report a rare case of tendinous xanthomatosis in a 23-year-old female, diagnosed on aspiration cytology. [ncbi.nlm.nih.gov]

  Lens opacification may require extraction at that time and aspirated lens material may contain lipid-containing vacuoles. [disorders.eyes.arizona.edu]

• Mild Clinical Course

  Because of this atypical presentation and mild clinical course, six patients were not initially diagnosed as having CTX. [brain.oxfordjournals.org]

• Joint Deformity

  An 18-year-old woman was admitted to our department because she presented with morning stiffness, joint deformation, and swelling in both hands. [ncbi.nlm.nih.gov]

  Xanthomas can cause motor restriction and joint deformities, resulting in ambulation disabilities. [jdrntruhs.org]

  An 18-year-old woman was admitted to our department because she presented with morning stiffness, joint deformation, and swelling in both hands. [ncbi.nlm.nih.gov]

• Osteopenia

  Osteopenia is evident by total body densitometry in untreated individuals. Individuals may have marked thoracic kyphosis. [leukodystrophyresourceresearch.org]

• Xanthoma

  Xanthomas are described as deposits in the skin and subcutaneous tissues. Mostly known as pseudotumors, xanthomas consist of connective tissue containing mainly cholesterol, triglycerides, and numerous foamy macrophages. [ncbi.nlm.nih.gov]

  Tendon xanthomas may cause discomfort and interfere with tendon flexibility. While many affected people develop tendon xanthomas, these nodules may not be easily visible underneath the skin. [ghr.nlm.nih.gov]

• Spinal Cord Syndrome

  None of them had cerebellar signs, dementia or peripheral neuropathy at the moment of presentation of the spinal cord syndrome and, except for patient B2, none of them had tendon xanthomas (Table 1 ). [brain.oxfordjournals.org]

Results : Laboratory workup revealed cholestanol of 19.6 mmol/L (Reference: 2-12 mmol/L) increased cholestanol/cholesterol rate of 4.55 ( Reference : 0.16 /- 0.05 ) and increased cerebrospinal fluid albumin of 24.4 mg dL (Reference: up to 3.5). [mdsabstracts.org]

MRI studies of the brain are an important component of the diagnostic workup for CTX. It may show bilateral hyperintensity of the dentate nuclei and cerebral and cerebellar white matter. [eyewiki.aao.org]

  Two unrelated individuals were referred to Lipid Clinics in The Netherlands and Chile with extreme xanthomatosis and hypercholesterolemia. [ncbi.nlm.nih.gov]

Successful long-term treatment of a number of affected individuals identified as children has been reported in the literature. Treatment with chenodeoxycholic acid normalizes the production of cholestanol. [rarediseases.org]

Treatment Early diagnosis and long-term treatment with a medication called chenodeoxycholic acid improves neurological symptoms and contributes to a better prognosis. [geneticdisordersuk.org]

Prognosis Early diagnosis and treatment are crucial to prevent progressive accumulation of cholestanol and cholesterol: disease progression may be halted and in some cases reversed. Treated patients may have a normal lifespan. [orpha.net]

Behavioral/personality disturbance in childhood or adolescence, especially when accompanied by learning difficulties, should therefore lead to further investigation to exclude CTX, as early diagnosis and treatment is critical for prognosis. [nature.com]

Prognosis If cerebrotendinous xanthomatosis is untreated, life expectancy is into the fifth and sixth decades; however, confirmed deaths have been reported as early as age 4 months. This is a progressive and terminal disease if left untreated. [emedicine.medscape.com]

Etiology CTX is caused by mutations in the sterol 27-hydroxylase gene ( CYP27A1 ; 2q33-qter). Sterol 27-hydroxylase catalyzes the first step in the oxidation of the side-chain of sterol intermediates in the bile acid synthesis (BAS) pathway. [orpha.net]
