RESUMO

INTRODUCTION: Lipoma Arborescens is a rare pathology that mainly affects the knee. Occurrences in the elbow are even more uncommon and mainly involve the bicipitoradial bursa. CASE'S DESCRIPTION: We describe the case of a 54-year-old patient known for rheumatoid arthritis, who consulted for chronic elbow pain associated with swelling and limited extension. DIAGNOSIS: The diagnosis of a lipoma arborescens of the elbow involving the whole joint was made using magnetic resonance imaging and confirmed during arthroscopy. INTERVENTIONS: After a failed nonoperative treatment consisting in intra-articular cortisone injections and physiotherapy, the patient underwent arthroscopic synovectomy and arthrolysis. OUTCOME: At 1-year follow-up, he reported no pain, satisfactory range of motion, and major improvements in clinical scores. CONCLUSION: This is the first illustrated case report about lipoma arborescens involving the whole elbow joint. Even though it is a rare disease, awareness of its presentation, imaging patterns, and treatment options is therefore important for clinicians, radiologists, and surgeons. In this case, arthroscopic treatment resulted in satisfactory and long-lasting pain relief and functional results. It may be considered as a safe and effective option in case of failed nonoperative measures.

RESUMO

Benign and malign tumors can affect the temporomandibular joint (TMJ) as any other articulation. Nevertheless, TMJ tumors are rare and mostly benign. Their clinical expression is varied including symptomatology similar to TMJ dysfunctional disorders, otologic or neurologic pathologies. In some cases, they remain totally asymptomatic. Hence, diagnosis is difficult since the symptomatology can be misleading with TMJ dysfunctional disorders or otologic disorders wrongly diagnosed. There is thus frequently a long delay between symptoms onset and diagnosis. The great variety of TMJ lesions explains the wide range of possible treatment modalities, mostly based on surgery. We provide here a review of the lesions originating from the TMJ. Tumoral or cystic mandibular lesion affecting the TMJ through local extension will not be discussed. Osteoma, osteoid osteoma, osteoblastoma, chondroma, osteochondroma, chondroblastoma, tenosynovial giant cell tumors, giant cell lesions, non-ossifying fibroma, hemangioma, lipoma or Langerhans cell histiocytosis are all possible diagnosis among the benign tumors found in the TMJ. Pseudotumors include synovial chondromatosis and aneurysmal bone cyst. Finally, malign tumors of the TMJ include mainly sarcomas (osteosarcoma, chondrosarcoma, synovial sarcoma, Ewing sarcoma, and fibrosarcoma), but also multiple myeloma and secondary metastases. We will review the clinical, radiological and histological aspects of each of these lesions. The treatment and the recurrence risk will also be discussed.

RESUMO

BACKGROUND: A small, incidental filar cyst associated with terminal lipoma is thought to be caused by failure of secondary neurulation; however, the precise embryologic background is not fully understood. Retained medullary cord (RMC) also originates from late arrest of secondary neurulation. The central feature of RMC histopathology is a central canal-like ependyma-lined lumen with surrounding neuroglial core. CASE DESCRIPTION: We surgically treated 2 patients with a large cyst in the rostral part of the filum and lipoma in the caudal filum. At cord untethering surgery, the filum was severed at the caudal part of the cyst. Histopathologically, the filar cyst was the cystic dilatation of the central canal-like structure at the marginal part of the lipoma. The central canal-like structure was continuous caudally in the lipoma, and its size decreased toward the caudal side. CONCLUSIONS: The present findings support the idea raised by Pang et al that entities such as filar cyst, terminal lipomas, and RMC can all be considered consequences of a continuum of regression failure occurring during late secondary neurulation.

RESUMO

The lipoma of the corpus callosum is a very rare benign congenital lesion, which can be isolated or associated with varying degrees of dysgenesis of the corpus callosum. It can be asymptomatic or revealed by nonspecific signs such as epileptic seizures, headache, neurological deficit or dementia. Sectional imaging makes diagnosis easily. We report the case of an 18-year-old boy who had a seizure in which imaging revealed a lipoma of the corpus callosum.

RESUMO

CASE PRESENTATION: The patient was a 72-year-old man who consulted with his previous physician for chief complaints of palpitations, fatigue, and blackish feces persisting for 1 month. After confirming the presence of anemia, the patient was referred to our hospital. Blood test findings upon hospital arrival revealed a hemoglobin (Hb) level of 6.0 g/dL. Computed tomography revealed a tumor of 32 mm × 30 mm with a low-density area extending from the bulb to the second part of the duodenum. Magnetic resonance imaging revealed high signal intensity on T1- and T2-weighted imaging and low signal intensity on fat-suppressed T2-weighted imaging, findings consistent with lipoma. Upper gastrointestinal endoscopy revealed a yellowish submucosal tumor that had perforated into the intestinal tract from the external wall extending from the upper corner to the second part of the duodenum. After determining that the tumor was sessile, laparoscopic partial duodenectomy with Roux-en-Y reconstruction was planned and performed. Pathology revealed a yellowish tumor 4 cm × 4 cm in size extending from the pyloric area to the duodenal bulb arising from the tunica muscularis. The present case report details our experience involving a patient who underwent surgical resection for hemorrhagic duodenal lipoma.

RESUMO

OBJECTIVE: Lumbosacral lipomas (LSLs), one form of closed spinal dysraphism, are congenital disorders of the terminal spinal cord (SC). Delayed neurologic deterioration often occurs in the subsequent developmental course of the patient. Identifying the cellular and molecular factors underlying the progressive damage to neural structures is a prerequisite for developing treatment strategies for LSLs. METHODS: Nine LSL specimens obtained from the SC/lipoma interface during surgical resection were examined. Normal SC tissue served as a control. Clinical characteristics were obtained, and spinal magnetic resonance imaging was re-evaluated. Cellular marker profiles were established. Immunoreactivity (IR) of hypoxia-inducible factor 1α (HIF-1α/-2α), erythropoietin (Epo)/erythropoietin receptor (EpoR), interleukin-1ß (IL-1ß)/IL-1R1, and tumor necrosis factor α/tumor necrosis factor receptor type 1 were analyzed qualitatively and semiquantitatively by densitometry. Colabeling with cellular markers was determined by multifluorescence labeling. Cytokines were further analyzed by real-time reverse transcription polymerase chain reaction. RESULTS: LSL specimens showed significant gliosis. HIF-1α/HIF-2α-IR and Epo/Epo-IR were found at significantly higher levels in the LSL specimens, as were IL-1ß-/IL-1ß receptor type 1 (IL1-R1) and tumor necrosis factor α/tumor necrosis factor receptor type 1 (P < 0.001), than were the controls. At the messenger RNA level, cytokines appeared partially induced. Double immunofluorescence labeling confirmed the costaining of these factors with inflammatory and glial markers. CONCLUSIONS: The expression of hypoxia-related and inflammatory mediators was shown for the first time in LSL specimens. These factors might play a role in multifactorial secondary lesion cascades underlying further damage to the neural placode in closed dysraphism.

RESUMO

AIM: To determine the clinical and radiographical aspects of six patients diagnosed with pericallosal lipomas (PCL). MATERIAL AND METHODS: A retrospective analysis of patients who presented to the neurosurgery outpatient clinics of Selcuk Faculty of Medicine between 2009 and 2019, revealed that six patients were diagnosed with PCL. The clinical and magnetic resonance imaging (MRI) data were obtained by reviewing patients? records. RESULTS: A total of six patients (two girls and four boys), with a mean age of 53.8 months (38?72 months), were included in this study. They were followed up for a mean period of 36.5 months (32?41 months). PCL were detected on MRIs, which were obtained to investigate headache in two patients, epilepsy in one patient, frontal dermal sinus tract and left frontal epidermoid tumor in one patient, and subcutaneous lipoma associated with PCL in one patient. Five patients displayed tubulonodular lipomas and one patient displayed curvilinear lipomas. Agenesis or dysgenesis of the corpus callosum (CC) was observed in four (66%) patients. Two patients received surgical treatment for cosmetic skin problem. CONCLUSION: Because of the benign course of PCL, i.e. no growth or very slow growth, and close proximity to the surrounding neurovascular structures, surgical removal should be considered only in symptomatic PCL. Furthermore, other malformations and anomalies may accompany PCL.

RESUMO

Adult intussusception is an uncommon cause of abdominal pain and poses diagnostic challenges for emergency physicians due to its varied presenting symptoms and time course. We report a case of chronic colocolic intussusception secondary to a lead point submucosal lipoma. Dedifferentiating intussusception with or without a lead point is important in determining appropriate management.

RESUMO

BACKGROUND: A cardiac lipoma is a rare primary cardiac tumor. They are usually asymptomatic and carry a good prognosis. Cardiac Magnetic Resonance Imaging (CMR) is the confirmatory investigation of choice. CASE PRESENTATION: We present a case of left ventricular lipoma in an asymptomatic patient, which was successfully treated with surgical resection. CONCLUSION: Cardiac lipomas are rare and are usually benign. There is no guideline on the management of cardiac lipomas and treatment is individualized.

RESUMO

Giant lipomas are rarely found in the head and neck region. A 67-year-old male patient presented with a massive ventral swelling of his neck extending from the lower margin of the mandible to the clavicle. The mass had slowly grown over 20 years without causing any symptoms, except for considerable psychological stress because of the disfiguration of the patient's profile appearance. Contrast magnetic resonance imaging suggested a lipomatous soft tissue lesion. The surgically removed tumor measured 32 × 20 × 4 cm. Surgery was completed without any intraoperative complications or injury to the critical structures of the neck. The patient was satisfied with the cosmetic result of the operation, and histopathological examination confirmed a lipoma.

RESUMO

CASE DESCRIPTION: A client-owned 12-year-old 10.3-kg (22.7-lb) female shusui koi (Cyprinus carpio) was evaluated because of an ulcerated mass on the left body wall, hyporexia, and decreased activity. CLINICAL FINDINGS: The patient was anesthetized with a solution of eugenol in water for all examinations and procedures. An approximately 7 × 5-cm smooth, raised, ulcerated, and firm mass was present ventral and lateral to the dorsal fin on the left body wall. Whole-body CT images obtained before and after contrast administration revealed an encapsulated, homogeneous, fat-opaque mass within the muscle. The mass was fat echoic with poor vascularity on ultrasonographic examination. Histologic evaluation of an ultrasound-guided needle biopsy specimen was suggestive of a lipoma. TREATMENT AND OUTCOME: The mass was excised, and the fish was placed in water with 0.3% salinity for 3 weeks after surgery. Postoperative antimicrobial administration was not indicated, and additional postoperative analgesic administration was considered impractical. The patient had noticeable improvement in appetite and activity with no indication of discomfort immediately following surgery. Five weeks after surgery, the incision site had healed with minimal scarring, and evaluation of CT images revealed no evidence of mass regrowth or regional osteomyelitis. CLINICAL RELEVANCE: Antemortem evaluation and diagnosis of a lipoma in a teleost with subsequent excision was described. This report highlighted the logistic challenges associated with anesthesia, advanced diagnostic imaging, and surgery in fish and showed that they can be successfully overcome so that high-level medical care can be provided to such patients.

RESUMO

PURPOSE: To build and validate a decision tree model using classification and regression tree (CART) analysis to distinguish lipoma and lipoma variants from well-differentiated liposarcoma of the extremities and superficial trunk. METHODS: This retrospective study included patients who underwent surgical resection and preoperative contrast-enhanced MR imaging for lipoma, lipoma variants, and well-differentiated liposarcoma in two tertiary referral centers. Six MRI findings (tumor size, anatomical location, tumor depth, shape, enhancement pattern, and presence of intermingled muscle fibers) and two demographic factors (patient age and sex) were assessed to build a classification tree using CART analysis with minimal error cross-validation pruning based on a complexity parameter. RESULTS: The model building cohort consisted of 231 patients (186 lipoma and lipoma variants and 45 well-differentiated liposarcoma) from one center, while the validation cohort consisted of 157 patients (136 lipoma and lipoma variants and 21 well-differentiated liposarcoma) from another center. In the CART analysis, the contrast enhancement pattern (no enhancement or thin septal enhancement versus thick septal, nodular, confluent hazy, or solid enhancement) was the first partitioning predictor, followed by a maximal tumor size of 12.75 cm. The tree model allowed distinction of lipoma and lipoma variants from well-differentiated liposarcoma in both the model building cohort (C-statistics, 0.955; sensitivity 80 %, specificity 94.62 %, accuracy 91.77 %) and the external validation cohort (C-statistics, 0.917; sensitivity 66.67 %, specificity 95.59 %, accuracy 91.72 %). CONCLUSION: The distinction of lipoma and lipoma variants from well-differentiated liposarcoma can be achieved with the simple classification tree model.

RESUMO

Los lipomas son tumores benignos compuestos por adipocitos maduros. Si bien representan la neoplasia más común en el cuerpo humano, su aparición en la región de la cabeza y el cuello es relativamente rara. No muestra predilección por sexo y afecta a individuos en la cuarta década de vida. Clínicamente, puede observarse un aumento de volumen nodular, de consistencia blanda y superficie lisa. Su etiopatogenia aún es desconocida, aunque algunos autores han sugerido factores endócrinos, inflamatorios, hereditarios y traumáticos. El diagnóstico se realiza a través de la evaluación clínica, con la ayuda de pruebas de imagen como la tomografía computarizada y la resonancia magnética. Sin embargo, solo puede ser confirmado mediante análisis histopatológico de la lesión, considerado el examen por excelencia. El tratamiento de los lipomas y todas sus variantes consiste en la extirpación quirúrgica total, con lo cual se disminuye la posibilidad de recidivas, que es rara de por sí. El objetivo de esta publicación es informar un caso clínico de lipoma localizado en la región de la mucosa yugal, con extirpación quirúrgica completa de la lesión de manera ambulatoria (AU)


Lipomas are benign tumors composed of mature adipo- cytes. Although they represent the most common neoplasia in the human body, their occurrence in the head and neck region is relatively rare. Regardless of gender, they affect individu- als from the fourth decade of life on. Clinically, an increase of the nodular volume with softened consistency and smooth surface can be observed. Although its etiopathogenesis is still uncertain, some authors have suggested endocrinal, inflam- matory, hereditary and traumatic factors. The diagnosis is made through clinical evaluation, with the aid of imaging ex- aminations, such as computerized tomography and magnetic resonance. However, it can only be confirmed through the histopathological analysis of the lesion, which is considered the gold standard examination. The treatment of the lipomas and all their variations consists of complete surgical exci- sion, thus diminishing the possibility of recurrence, which in turn is rare. The aim of this publication is to report a clin- ical case of lipoma, located in the jugal mucosa region and treated through complete surgical removal of the lesion on an outpatient basis (AU)

RESUMO

Multiparametric ultrasound (MPUS), combining conventional techniques (greyscale and colour Doppler ultrasound), ultrasound strain elastography, and contrast-enhanced ultrasound (CEUS), has been successfully used in the assessment of adult scrotal pathology. Contrast-enhanced ultrasound can confidently establish testicular tissue vascularity even in the small-volume paediatric testis. Elastography provides further assessment of tissue stiffness, potentially adding useful diagnostic information. In children, ultrasonography is particularly advantageous, being safe, radiation-free and negating the need for sedation or general anaesthesia during the imaging evaluation. In this review article, we aim to familiarise readers with the MPUS scanning protocol used for paediatric scrotal examination and provide an overview of scrotal MPUS features, with particular focus to clinical indications where MPUS may be advantageous over conventional ultrasonography.
