“…[ 38 ] Table 1 illustrates a cumulative literature review of LMS as well as the unique manifestation of LMS in the ethmoid air cells and frontal sinus within the context of an immunocompetent patient presented in this case report. [ 1 , 3 , 5 , 6 , 8 , 10 , 13 , 16 , 19 , 20 , 22 - 24 , 26 , 29 , 33 , 35 - 37 ]…”

“…[38] Table 1 illustrates a cumulative literature review of LMS as well as the unique manifestation of LMS in the ethmoid air cells and frontal sinus within the context of an immunocompetent patient presented in this case report. [1,3,5,6,8,10,13,16,19,20,[22][23][24]26,29,33,[35][36][37] Examination of Table 1 highlights the fact that no reported LMS has been reported with the same spatial distribution. Furthermore, the total number of reported primary intracranial LMS is 52 and the average age of these patients was 41.98 ± 17.99 years.…”

Primary intracranial leiomyosarcoma presenting with frontal bone mass: a case report

“…These tumors can mimic meningioma on imaging. Primary intracranial LMS is much rare tumor and we could find 16 reported cases till 2018 [ 1 ] and two cases in 2019 [ 2 , 3 ] and three cases in 2020 [ 4 - 6 ]. It has been reported to be less than 1% of brain biopsy that was about 3 out of 25,000 primary brain tumors [ 2 ].…”
