Latar Belakang: Meningioma adalah tumor intrakranial primer yang paling umum
dengan insiden 2,3 – 8,3 per 100.000 orang. Indeks Ki-67 menjadi faktor yang
konsisten untuk membedakan meningioma anaplastik dan jinak. Temuan Radiologic
feature, lokasi, lateralisasi meningioma pada pemeriksaan MRI kepala berguna dalam
memprediksi Ki-67 pada pasien meningioma untuk menentukan prognosis dan terapi.
Tujuan: Penelitian ini bertujuan mengetahui hubungan antara radiologic feature,
lokasi dan lateralisasi Meningioma pada pemeriksaan MRI kepala dengan ekspresi Ki-
67.
Metode: Penelitian dengan desain cross sectional ini dilakukan di RSUP Dr Sardjito
Yogyakarta dengan mengambil data sekunder dari pasien yang melakukan
pemeriksaan MRI kepala dan patologi anatomik dengan hasil Meningioma di RS
Sardjito Yogyakarta periode Januari 2019-November 2023. Subjek diambil
menggunakan purposive sampling. Foto MRI kepala dan hasil Ki-67 dari 29 subjek
yang memenuhi kriteria inklusi diambil untuk dianalisis. Data diambil dari PACS dan
rekam medis.
Hasil: Mayoritas sampel berjenis kelamin perempuan (82,8%) dan rerata berusia 51,1
tahun. Lokasi meningioma terbanyak di Convexity (69,0). Lateralisasi didapatkan pada
22 pasien (75.9%). Derajat histopalogi menurut grading WHO terbanyak grade
1(44.8%). Terdapat hubungan yang signifikan ukuran tumor pada Radiologic features
dengan Ki 67 (p=0,014, r=0,450). Didapatkan Hubungan yang signifikan antara
lateralisasi dengan Ki 67 (p=0,046; r=0,373). Tidak ditemukan hubungan yang
signifikan antara lokasi Meningioma dengan Ki 67 (p=0,989; r=0,003).
Kesimpulan: Terdapat hubungan yang signifikan ukuran tumor pada Radiologic features
dengan Ki 67. Terdapat hubungan yang signifikan antara lateralisasi dengan ki 67. Tidak
ditemukan hubungan yang signifikan antara lokasi Meningioma dengan Ki 67
(p=0,989; r=0,003).

Background: Meningioma is the most common primary intracranial tumor with an
incidence of 2.3 – 8.3 per 100,000 people. The Ki-67 index is a consistent factor for
differentiating anaplastic and benign meningiomas. Radiologic feature findings,
location, lateralization of meningioma on MRI of the head are useful in predicting
Ki-67 in meningioma patients to determine prognosis and therapy.
Objective: This study aims to determine the relationship between radiological
features, location and lateralization of meningioma on head MRI examination with
Ki-67 expression.
Method: This research with a cross sectional design was carried out at Dr Sardjito
Hospital Yogyakarta by taking secondary data from patients who underwent head
MRI and anatomical pathology examinations with Meningioma results at Sardjito
Hospital Yogyakarta for the period January 2019-November 2023. Subjects were
taken using purposive sampling. Head MRI photographs and Ki-67 results from 29
subjects who met the inclusion criteria were taken for analysis. Data were taken from
PACS and medical records.
Results: The majority of the sample was female (82.8%) and the average age was
51.1 years. The most common meningioma locations were in Convexity (69.0).
Lateralization was found in 22 patients (75.9%). The highest degree of histopology
according to WHO grading was grade 1 (44.8%). There is a significant relationship
between tumor size and radiologic features with Ki 67 (p=0.014, r=0.450). A
significant relationship was found between lateralization and Ki 67 (p=0.046;
r=0.373). No significant relationship was found between Meningioma location and
Ki 67 (p=0.989; r=0.003).
Conclusion: There is a significant relationship between tumor size and radiologic
features with Ki 67. There is a significant relationship between lateralization and Ki
67. There was no significant relationship between the location of the meningioma
and Ki 67 (p=0.989; r=0.003).
