Fatal sclerosing mesenteritis: a 7-year-old male autopsy case report

ABSTRACT Sclerosing Mesenteritis (SM) is a rare diagnosis, particularly in pediatric patients, and is typically non-fatal when appropriately treated. Although molecular and immunohistochemical alterations have been described, no pathognomonic signature has been identified for this entity. This report presents a case of a seven-year-old boy who suffered sudden cardiorespiratory arrest. Upon autopsy, he was found to have multicentric SM on the upper mesentery, which led to bowel wall thinning and abdominal bleeding with bacterial translocation. We performed comprehensive morphological, immunohistochemical, and molecular analyses. SM is an atypical disorder with diverse clinical manifestations, including a rare but potentially fatal course. Early diagnosis is critical, given its potential severity. To our knowledge, this is the first case report of pediatric mortality linked to SM. Our findings emphasize the importance of increased awareness and early detection of SM in pediatric patients.

Paniculitis mesentérica como causa de masa abdominal palpable / Mesenteric panniculitis as a cause of palpable abdominal mass

RESUMEN Introducción: la paniculitis mesentérica es un trastorno poco frecuente caracterizado por inflamación crónica del tejido adiposo del mesenterio intestinal, su etiología es desconocida. Objetivo: describir la presentación clínica y radiológica de un paciente con paniculitis mesentérica atendido en el Hospital Militar Dr. Carlos J. Finlay de La Habana, Cuba. Caso clínico: paciente masculino de 62 años de edad, con antecedentes de salud aparente, ex fumador que hace seis meses, notó la presencia de una masa abdominal localizada en el cuadrante inferior izquierdo del abdomen. Se diagnostica paniculitis mesentérica. Conclusiones: a pesar de ser una entidad poco frecuente, la paniculitis mesentérica, debe ser considerada en el diagnóstico diferencial de los pacientes con masa abdominal palpable, empleando los medios imagenológicos para su estudio.

ABSTRACT Introduction: mesenteric panniculitis is a rare disorder characterized by chronic inflammation of the adipose tissue of the intestinal mesentery, its etiology is unknown. Objective: to describe the clinical and radiological management of a patient with mesenteric panniculitis treated at Dr. Carlos J. Finlay Military Hospital in Havana, Cuba. Clinical case: a 62-year-old, male patient with apparent health history, ex-smoker. Six months ago, the patient noticed the presence of an abdominal mass located in the lower left quadrant of the abdomen. Mesenteric panniculitis is diagnosed. Conclusions: in spite of being a rare entity, mesenteric panniculitis should be considered in the differential diagnosis of patients with palpable abdominal mass, where the imaging studies are valuable for its diagnosis.

An analysis of clinical characteristics of twelve cases of mesenteric panniculitis / 中华内科杂志

Objective Mesenteric panniculitis is an idiopathic , uncommon disease involving the adipose tissue of mesentery .The etiology , diagnosis and treatment are still unnoticed .We thus reported a case series to improve the understanding of this rare disorder .Methods We retrospectively analyzed the clinical data of 12 patients with mesenteric panniculitis including manifestation , diagnosis, treatment and prognosis.Results We found a male predominance (M∶F 3∶1) with the median age of 58 years old at diagnosis.The most common symptom was abdominal pain (9/12), followed by abdominal distension (3/12) and weight loss (3/12).Physical examination was unremarkable in the majority of patients (8/12).C reactive protein (9/12) and erythrocyte sedimentation rate (10/12) were normal in majority of patients.CT findings were of much diagnostic value .All patients had small intestinal mesentery involvement and multi-nodular appearance with increased fat density .Pseudo-capsule sign ( 8/12 ) and fat halo sign (6/12) were common.Pathological diagnosis was obtained in 4 cases showing fat tissue inflammation with local necrosis and fibrosis .Six cases all received prednisone , 2 with combined cyclophosphamide , 1 with azathioprine, 1 with tripterygium wilfordii .Short-term clinical response was achieved in all cases , but two patients relapsed .Conclusions Mesenteric panniculitis occurs predominantly in middle-aged and elderly . Abdominal pain is the leading symptom .Inflammatory markers are often normal while computed tomography is the most important diagnostic tool .Surgery combined with cortical steroid and immunosuppressant agents is effective.

Spontaneous Regression of Sclerosing Mesenteritis Presenting as a Huge Mass / 대한소화기학회지

Sclerosing mesenteritis is a rare benign disease originated from the mesenteries. It can be related to autoimmune disease, vasculitis, ischemia, infection, trauma and operation, but most of cases are idiopathic. The overall prognosis of sclerosing mesenteritis is usually good with benign, course. However, no consensus of treatment has yet been established. We report a case of spontaneous partial regression of sclerosing mesenteritis presented as a huge mass and diagnosed by finding of contrast enhanced abdominal computed tomography and percutaneous ultrasonography guided needle biopsy.
