Abstract

ABSTRACT The simple bone cyst,or traumatic bone cyst, solitary or idiopathic bone cavity is an intraosseous pseudocyst discovered through a panoramic radiographic examination. Commonly, the SBC is presented as an asymptomatic lesion, radiolucent, unilocular, without cortical expansion, with margins adorning vital tooth roots of the affected region. The literature has recommended that clinical and radiographic aspects of simple bone cyst are quite convincing as to diagnosis, so follow-up through clinical and radiographic examination has been suggested. This case illustrates an exuberant clinical case of simple bone cyst, which was presented as multilocular and expansive lesion in a 7-year-old patient. Surgical exploration was performed because her parents were anxious about the presumptive diagnosis of other more aggressive lesions. The diagnosis of SBC was confirmed. The case was monitored and, after three years, total bone remodeling of the affected area was observed. In conclusion, asymptomatic radiolucent lesions that suggest a strong presumptive diagnosis of a simple bone cyst can be clinically and radiographically monitored. However, clinical variations, as in the present clinical case, require confirmation of the diagnosis, which is performed through exploratory surgery. The establishment of the diagnosis affords the safest approach for both the professional and the patient.

Highlights

A simple bone cyst (SBC), referred to as traumatic or solitary bone cyst, or idiopathic bone cavity, is considered an intraosseous pseudocyst devoid of epithelial lining, containing serosanguineous fluids or none at all[1,2,3,4]
The SBC is seen more in the second decade of life, the mandible being the region most frequently affected[1]. It appears radiolucent, unilocular or multilocular, almost always without cortical expansion, with the margins adorning the roots of the teeth in the affected region[1,2,3,4]
It is asymptomatic and its final diagnosis is obtained during exploratory surgery, when the surgeon confirms that the cavity is empty[1,2,3]

INTRODUCTION

A simple bone cyst (SBC), referred to as traumatic or solitary bone cyst, or idiopathic bone cavity, is considered an intraosseous pseudocyst devoid of epithelial lining, containing serosanguineous fluids or none at all[1,2,3,4]. The SBC is seen more in the second decade of life, the mandible being the region most frequently affected[1] It appears radiolucent, unilocular or multilocular, almost always without cortical expansion, with the margins adorning the roots of the teeth in the affected region[1,2,3,4]. It is asymptomatic and its final diagnosis is obtained during exploratory surgery, when the surgeon confirms that the cavity is empty[1,2,3]. Over the course of 3 years, the affected region was completely repaired, revealing the formation of a lamina dura and no alteration to the permanent erupted teeth, corroborating the literature with regard to prognosis (figure 5)
