Madelung disease is defined by multiple symmetric fatty accumulations, usually involving the upper trunk, and may sometimes have excessive fat deposition in the prevertebral space. On magnetic resonance imaging (MRI), findings of fat that are hyperintense on T1w and T2w images, may simulate subacute hematoma and mimic cervical spine injury. This is the first reported case of Madelung disease with prevertebral fat deposition mimicking prevertebral hematoma found in cervical spine injury on MRI. Fat suppression techniques are helpful in order to differentiate between these two conditions, which should be taken into consideration during routine clinical practice.

Madelung's disease is a rare metabolic disorder characterized by a symmetrical accumulation of nonencapsulated adipose tissue deposits, mainly around the head, neck and shoulders. Fat deposits can grow and put pressure on other organs causing a variety of symptoms, inter alia, dysphagia, breathing difficulties, neck stiffness and headache. Madelung's disease is often accompanied by other disorders such as diabetes, hypertension, hypothyroidism, or liver disease. In addition to somatic issues, mental health problems may also develop causing social exclusion and depression. Middle-aged men with a history of alcohol abuse are the most commonly affected. Various imaging techniques, including computed tomography (CT), are helpful in stating the diagnosis. This paper presents a case of a 33-year-old man with extensive adipose tissue overgrowth around neck and chest. CT-enhanced scans with multiplanar reconstruction (MPR) and volume rendering technique (VRT) reconstruction are also included.

Madelung's disease is a rare benign systemic lipomatosis, which often presents in the head, neck and upper trunk regions. The appearance of symmetrical, excessive adipose tissue in the subcutaneous layer is its clinical characteristic. Orbital involvement is unusual with only a few cases reported previously. In this study, we describe the clinical and radiological features of Madelung's disease in the orbits. A 42-year-old man with alcohol addiction presented with chronic bilateral masses of the lower eyelids and proptosis. Computed tomography (CT) scan showed excessive symmetrical non-encapsulated fat deposition in the orbital fat, lower eyelids, salivary glands, subcutaneous tissue along the neck and under the sternocleidomastoid muscles and supraclavicular areas bilaterally. Histopathological study of the orbital masses revealed mature adipose tissue interspersed with thin fibrous septae. He developed recurrent lipomatosis 1 year after surgical excision.

We present an unusual case of SHOX deficiency associated with Léri-Weill dyschondrosteosis (LWD), Hashimoto's thyroiditis and pseudohypoparathyroidism 1B in a young woman. To our knowledge, this is the first ever report of these disorders coexisting. At the age of nine years, the proband was diagnosed of hypothyroidism due to Hashimoto's thyroiditis, and developed biochemical abnormalities consistent with hyperphosphatemia, mild hypocalcemia and elevated parathyroid hormone without any clinical symptoms except short stature. Replacement therapy with levothyroxine, calcium and alphacalcidol was initiated. The diagnosis of pseudohypoparathyroidism 1B was confirmed at the age of 17.5 years with the demonstration of methylation alteration at the GNAS locus. At the age of 16 years, 3.5 years after her menarche, she presented clear features of LWD. A large deletion of the SHOX gene was confirmed. Family genetic tests were not doable since she was adopted. We discuss the diagnostic challenges of these coexisting rare endocrinopathies.

BACKGROUND: Multiple Symmetric Lipomatosis (MSL) is a rare disorder related to fat metabolism and lipid storage. The condition results in characteristic depositions of fat, especially around the cephalic, cervical, and upper thoracic subcutaneous. It is much more common in adult males who live in the Mediterranean region and has only rarely been reported in Asian females. In this report, we present a case of an Asian female with MSL and also review the clinical features of the condition, including radiological and histological findings required for proper diagnosis and management. CASE PRESENTATION: A 59-year-old Korean female came in with a chief complaint of palpable mass present in shoulder and upper back regions. Images showed diffuse non-encapsulated adipose tissue in the subcutaneous layer of the suboccipital, posterior neck area. The patient wanted to remove the mass for cosmetic reasons and discomfort. Excisional biopsy was planned. Preoperative blood analyses showed deteriorated liver function, and the computed tomography findings were consistent with liver cirrhosis. Detailed history taking revealed that she consumed highly levels of alcohol. Lipectomy was performed and the histological findings demonstrated large dystrophic adipocyte morphology. The patient was recovered uneventfully. CONCLUSION: When patients have multiple symmetric lipomatous lesions, clinicians should suspect MSL and survey possible associated conditions, such as alcoholism, liver cirrhosis, dyspnea, and neuropathy in detail.

BACKGROUND: Madelung's disease (MD) is a rare disorder of fat metabolism, which is usually associated with diabetes, hyperuricemia, liver disease, nevertheless there is no report of a patient with MD and pulmonary aspergillosis (PA). This article aimed to enhance the awareness of this two diseases and discuss the possible mechanism of the combination of them preliminarily. CASE PRESENTATION: In this case, we described a 56-year-old male patient with cough, expectoration and dyspnea. His neck has a very peculiar appearance. Chest enhanced CT scan showed there were multiple nodules in both lungs, some of which had cavities and the mediastinal lymph nodes were swollen. Ultrasound scan of the neck showed diffuse hyperplasia of subcutaneous fat in neck and bilateral supraclavicular fossa. Fortunately, after performing pulmonary wedge resection aimed at pathological examination and giving relevant treatments, this patient was finally diagnosed as MD with PA, and his symptoms were significantly relieved. CONCLUSIONS: MD is rare, the phenomenon that MD combined with PA is rarer. Immune disorder may be the possible mechanism.

The frequency of dermatological manifestations in diseases due to mitochondrial DNA mutations is not well known, although multiple symmetric lipomatosis has been repeatedly associated to mitochondrial DNA mutations. Here, we present a patient suffering from multiple symmetric lipomatosis and other skin signs. We found a new mitochondrial DNA mutation, m.8357T>C, in the tRNALys -coding gene and, using a cybrid approach, confirmed its pathogenicity. A meta-analysis of the dermatological signs of the patient shows that they are not common in patients with confirmed mitochondrial DNA mutations and suggests that, in these cases, lipomatosis is not related to the oxidative phosphorylation dysfunction, but to an alteration of an additional function associated to particular mitochondrial tRNAs.

INTRODUCTION: Madelung's disease (MD) is a rare disorder of unknown etiology defined as the presence of multiple and symmetrical fatty accumulations most commonly involving the upper trunk, neck, and head. Excessive alcohol ingestion has been linked traditionally to the pathogenesis of the disease. The central and peripheral nervous system could both be affected. Presenile dementia, without alcohol abuse, has been rarely reported in the literature as a complication. AIM: The aim of this case report is to highlight that multiple symmetric lipomatosis can be complicated by presenile dementia even if the patient is non-alcoholic. CASE REPORT: This case report describes a middle age non-alcoholic woman who presented for increased forgetfulness. Brain CT scan showed cerebral and cerebellar atrophy inappropriate for her age. Despite being started on anticholinergic drug, her MMSE decreased 3 points in 1 year. CONCLUSION: Clinicians should consider early onset dementia as a potential complication of Madelung's disease even in patients with no preceding history of alcoholism. A brain MRI and MMSE can aid with identifying such a complication.

INTRODUCTION: Madelungs disease is a rare illness manifested by the uncontrollable proliferation of unencapsulated adipose tissue which accumulates symmetrically in the hypodermis in the area of the neck, shoulders, back and thighs. As part of differential diagnosis it is necessary to investigate tumours in the area of the neck, dysfunction of the thyroid gland, Cushings syndrome and rare lipomatosis. CASE REPORT: In the case report, the authors present the case of a 52-year-old male patient with a large formation on the neck, trunk and the scrotal area. A suspicion of liposarcoma was expressed based on the imaging examinations performed. RESULTS: Excisions of tumorous loci on several occasions were indicated for the patient. Lipomas without abnormalities were proven in all histolo-gical examinations. CONCLUSION: The diagnosis of Madelungs disease is based on the clinical findings, imaging (computed tomography CT, magnetic resonance imaging MRI) and biopsy examination. Laboratory methods tend to focus rather on associated internal diseases. Treatment is only symptomatic and consists in surgical removal of the foci. However, it is often associated with the risk of recurrence.

Madelung's disease is characterized by the manifestation of multiple ectopic lipomas, usually found in the cervical-thoracic region, however, clinical manifestation may vary among patients. It has been postulated that lipomas associated with Madelung's disease are linked to brown adipose tissue (BAT) due to the presence of uncoupling protein 1 (UCP1). Therefore, we here investigated whether BAT activity is present in a patient with Madelung's disease. 18 F-fluorodeoxyglucose (18 F-FDG) uptake using PET/CT after a cooling procedure was measured together with body temperature and energy expenditure. Finally, adipose tissue biopsies were taken from the lipomas for gene expression analysis and histology. 18 F-FDG uptake was not detected after the cooling procedure in the lipomas. Furthermore, adipose tissue biopsies derived from the lipomas did not express UCP1. We thus conclude that cold-stimulated BAT activity was not detected in lipomas associated with Madelung's disease. Additional research in other patients is needed to unravel the role of dysfunctional BAT in Madelung's disease.

BACKGROUND: The main feature of Madelung disease (MD), a rare condition, is the growth of adipose tissue without a capsule. Usually, this disease is known for its prominent features with fat deposition around the neck, shoulder, back, or chest wall. Clinically, the patient is likely to exhibit alcohol, neuropathy, and metabolic disorders; however, no clear cause has been confirmed. AIMS: The aim of this study was to analyze the morphological, pathophysiological, and various treatment methods of MD. We have presented and discussed 16 cases of treatment of this disease at our hospital and reviewed the literature on this subject. METHODS: We carried out a retrospective chart review of 16 consecutive patients with MD treated from 1989 through 2017. Patient demographic data, tumor size and location, and follow-up data were evaluated. Patients usually seek treatment because of the disfigured appearance, restricted range of the motion of the head and neck, inconvenience in daily activity such as eating or speaking, and worry about the mass effect. All patients underwent surgical resection and/or combined liposuction. RESULTS: Among the patients, 14 were men, aged 38 to 80 years, with a history of disease ranging from 6 months to 7 years. The mean duration from symptoms to diagnosis of MD was 4.4 years. The mean duration of follow-up was 82.8 months (range, 5-192 months). Three patients died of coronary artery disease at follow-up of 27, 78, and 141 months. The functional results were satisfactory in all patients. Severe complications were not observed. CONCLUSIONS: According to our experience, surgical resection is the main method of improving the appearance, ensuring eradication of the tumor, and reducing the possibility of recurrence. In addition, we have a case in which atypical changes were confirmed by histological examination in fractional surgery. A long follow-up period is recommended considering the high propensity and mean time to recurrence. Although malignant transformation of MD is rare occurrence, it occurred in 1 of the 16 patients.

BACKGROUND: Multiple symmetric lipomatosis (MSL) is characterized by upper-body lipomatous masses frequently associated with metabolic and neurological signs. MFN2 pathogenic variants were recently implicated in a very rare autosomal recessive form of MSL. MFN2 encodes mitofusin-2, a mitochondrial fusion protein previously involved in Charcot-Marie-Tooth neuropathy. OBJECTIVE: To investigate the clinical, metabolic, tissular, and molecular characteristics of MFN2-associated MSL. METHODS: We sequenced MFN2 in 66 patients referred for altered fat distribution with one or several lipomas or lipoma-like regions and performed clinical and metabolic investigations in patients with positive genetic testing. Lipomatous tissues were studied in 3 patients. RESULTS: Six patients from 5 families carried a homozygous p.Arg707Trp pathogenic variant, representing the largest reported series of MFN2-associated MSL. Patients presented both lipomatous masses and a lipodystrophic syndrome (lipoatrophy, low leptinemia and adiponectinemia, hypertriglyceridemia, insulin resistance and/or diabetes). Charcot-Marie-Tooth neuropathy was of highly variable clinical severity. Lipomatous tissue mainly contained hyperplastic unilocular adipocytes, with few multilocular cells. It displayed numerous mitochondrial alterations (increased number and size, structural defects). As compared to control subcutaneous fat, mRNA and protein expression of leptin and adiponectin was strikingly decreased, whereas the CITED1 and fibroblast growth factor 21 (FGF21) thermogenic markers were strongly overexpressed. Consistently, serum FGF21 was markedly increased, and 18F-FDG-PET-scan revealed increased fat metabolic activity. CONCLUSION: MFN2-related MSL is a novel mitochondrial lipodystrophic syndrome involving both lipomatous masses and lipoatrophy. Its complex neurological and metabolic phenotype justifies careful clinical evaluation and multidisciplinary care. Low leptinemia and adiponectinemia, high serum FGF21, and increased 18F-FDG body fat uptake may be disease markers.
