A Bizarre Presentation of Bilateral Mandibular Osteoporotic Bone Marrow Defect (A Case Report)

Abstract

BACKGROUND: Osteoporotic bone marrow defect of the jaw is an uncommon localized radiolucency that consists of hematopoietic red marrow with varying amounts of fatty yellow marrow. The lesion is usually asymptomatic and accidentally discovered during a routine radiographic examination; however, some studies showed different results.
 CASE REPORT: This is an uncommon case of bilateral mandibular osteoporotic bone marrow defect in a 40-year- old healthy female. One of the defects reoccurred, and it involves dental implants. 
 PLAN OF TREATMENT: Lesion was managed by curettage and the patient was followed up after 1,6,12 months.
 CONCLUSIONS: in order to diagnose FOBMD and differentiate it from other lesions, further researches are needed to help fully understand it, since the exact incident and etiology are not established yet.

Are imaging exams relevant in aiding the diagnosis of focal osteoporotic bone marrow defect: A systematic review

“…Patients were all asymptomatic in 13 articles, but some studies documented symptoms ( Crawford and Weathers, 1970 , Sanner and Ramin, 1977 , Schneider et al, 1988 , Correll and Wescott, 1983 , Sa’do et al, 1992 , Bouquot et al, 2002 , Sençimen et al, 2011 , Almeida et al, 2014 , Garcia et al, 2015 , Yesancas-Pallares et al, 2016 , Kim et al, 2017 , Al-Ramzi et al, 2020 ;). Pain and edema were among the reported symptoms.…”

“…All cases performed biopsies to confirm the diagnosis, and two studies made a curettage in the lesion ( Haen et al, 2009 , Al-Ramzi et al, 2020 ). Only one study reported a lesion follow-up after the biopsy ( Almeida et al, 2014 ).…”

“…As for implants, seven studies demonstrated FOBMD associated with installed implants ( Lee et al, 2013 Apr , Garcia et al, 2015 , Al-Ramzi et al, 2020 , Almeida et al, 2014 ). One article showed implant displacement to the body of the mandible after insertion, and the implant was surgically removed after the diagnosis ( Lee et al, 2013 ).…”

“…Shankland and Bouqout (2004) showed the bilateral occurrence of this lesion in 3 % of patients. This systematic review found four bilateral cases in the posterior mandibular region ( Bouquot et al, 2002 , Ida-Yonemochi et al, 2010 , Almeida et al, 2014 , Oliveira et al, 2015 ), one in the anterior maxillary region ( Al-Ramzi et al, 2020 ), and a prevalence study with bilateral cases as well ( Yesancas-Pallares et al, 2016 ).…”
