case_images: A 50-year-old female patient with headaches for 4 weeks. A : A follow-up magnetic resonance imaging (MRI) scan shows tumor recurrence in 8 years after the surgery. B : Three-dimensional reconstruction of the cranial vault with a minimally invasive craniotomy (red) in the area of a conventional craniotomy. C : A follow-up MRI scan made 5 years after the reoperation showed no tumor recurrence.

case_images: An MRI scan showed tumor recurrence with signs of hemorrhage within the tumor (Fig. 1A). A MIC was performed (Fig. 1B). The follow-up examination made 5 years later showed no tumor recurrence (Fig. 1C).

case_images: A 44-year-old female patient with a recurrent oligodendroglioma in the right frontal lobe. A : An axial T1-weighted contrast-enhanced magnetic resonance image shows a small recurrent tumor in the right frontal lobe (red arrow). B : Three-dimensional reconstruction of the cranial vault shows a minimally invasive craniotomy (red) in the area of a conventional craniotomy.

case_images: Since the patient had already received radiation therapy and chemotherapy had not stopped the tumor growth, the only alternative left was surgical treatment (Fig. 2A). The MIC was performed, which allowed the recurrent tumor to be resected (Fig. 2B).

case_images: A 56-year-old female patient with a recurrent falcine meningioma. A : A coronal T1-weighted contrast-enhanced magnetic resonance image shows a recurrent falcine meningioma on the left. B : Three-dimensional reconstruction of the cranial vault with a minimally invasive craniotomy (red). C : A follow-up magnetic resonance imaging scan made 4 years after the reoperation showed no tumor recurrence.

case_images: f3-jkns-2024-0085
case_images: Over a period of 10 years, her recurrent tumor had been progressing (Fig. 3A). The tumor was completely removed using minimally invasive approach (Fig. 3B). The brain MRI scan made 4 years after the surgery showed no tumor recurrence (Fig. 3C).

case_images: A 77-year-old female patient with a recurrent right sphenoid wing meningioma. A : A follow-up magnetic resonance imaging (MRI) scan made 8 years after the surgery showed tumor recurrence. B : Intraoperative image of the minimally invasive craniotomy size. C : A follow-up MRI scan made 3 months after the reoperation showed no tumor recurrence.

case_images: f4-jkns-2024-0085
case_images: Due to the progress of a recurrent tumor and its contact with the arteria cerebri media, a reoperation was performed (Fig. 4A). The tumor was completely resected (Fig. 4B). A follow-up MRI scan made 3 months later showed no tumor recurrence (Fig. 4C).

case_images: A 67-year-old female patient with a diagnosed glioblastoma in the right frontal lobe. A : A magnetic resonance imaging (MRI) scan made after a tumor biopsy : an axial T1-weighted contrast-enhanced image shows a large tumor in the right frontal lobe with signs of midline shift. B : Three-dimensional reconstruction of the cranial vault which shows the minimally invasive craniotomy (red) size in the craniotomy area used for the tumor biopsy. C : A follow-up MRI scan made 1 year after the surgery showed no glioblastoma recurrence.

case_images: A 58-year-old female patient with a recurrent oligodendroglioma in the right temporal lobe. A and B : An axial T2-weighted magnetic resonance image and a fluoroethyl tyrosine-computed tomography scan show a recurrent tumor in the right temporal lobe. C : Three-dimensional image of the cranial vault shows the minimally invasive craniotomy (red). D : A follow-up magnetic resonance imaging scan made 2 years after the last surgery showed no tumor recurrence.

case_images: Follow-up MRI and fluoroethyl tyrosine-CT scans showed recurrence, so there was an indication for reoperation (Fig. 6A and B). The MIC was successful (Fig. 6C). A follow-up MRI scan made 2 years later showed no tumor recurrence (Fig. 6D).

case_images: A 52-year-old female patient with a recurrent left sphenoid wing meningioma. A : A follow-up magnetic resonance imaging (MRI) scan made 11 years after the surgery showed tumor recurrence. B : Three-dimensional reconstruction with a minimally invasive craniotomy (red) image. C : A follow-up MRI scan made 2 years after the reoperation showed no tumor recurrence.

case_images: Tumor recurrence was detected 11 years after the surgery (Fig. 7A). Subtotal resection of the meningioma was performed via MIC (Fig. 7B). A follow-up MRI scan made 2 years later showed no tumor recurrence (Fig. 7C).
