WCA/6033/2023

 

Diagnosis:   Right sided posterior frontal SOL/ High grade glioma r/o High grade meningioma

 

Operation- Stealth guided resection of intrinsic right posterior frontal tumor

Date of Admission- 15/02/2023

Date of Operation- 21/02/2023

Reason for delay (need to stay off clopidrogel for at least five days)

 

Background Information- A 74yr old woman who presented today on account of 3months history of recurrent seizures. Eight days history of slurring of speech. She was in her usual state of health until three months ago when she suddenly had seizures which was characterized by abnormal jerking and gnashing of teeth, However, no loss of consciousness, no foaming in the mouth, no incontinence, nor involvement of the limb. About eight days ago, her quality of speech changed (deteriorated) to a slurred state. There is also associated left upper limb weakness. No visual impairment, anosmia, memory charges, no history of trauma, swelling in any part of the body. A known hypertensive on medications. Not a known diabetic. No previous history surgery.

On examination:- an elderly woman, not pale, anicteric , afebrile, acyanosed.

Neurological Examination GCS =15/15

                                              Pupils=3mm, reactive

                                             Ambulates with supports

Left upper limb: hypertonia, power= 4/6 and hypereflexia

Right upper limb = NAD

Right lower limb = NAD

Patchy areas of patchy hyperesthesia

 

On account of above presentation, and on clinical suspicion of space occupying lesion in the brain,  Gadolinium enhanced Brain MRI (below) already done before presentation was reviewed  and it showed a dura based in-homogenous contrast enhancing mass situated on the right posterior frontal lobe, with significant peri-lesional edema.


 

 

A diagnosis of intrinsic brain tumor was made with a strong differential diagnosis of durally based high grade Meningioma was made. This diagnosis was explained to the basic understanding of the patient as well as the treatment options especially the need t proceed with image guided surgical excision of the tumor. This will not unly provide tissue diagnosis but also achieve cytoreduction and set the stage for necessary oncology referrals and adjuvant treatments.

And following informed consent, she was prepared and underwent  surgery as outlined above.
