Surgical outcome in patients with MRI-negative, PET-positive temporal lobe epilepsy.

Purpose: The purpose of this study was to determine the long-term surgical outcomes of magnetic resonance imaging (MRI)-negative, fluorodeoxyglucose positron emission tomography (FDG-PET)-positive patients with temporal lobe epilepsy (TLE) and compare them with those of patients with mesial temporal sclerosis (MTS).

Methods: One hundred forty-one patients with TLE who underwent anterior temporal lobectomy were included in the study. The surgical outcomes of 24 patients with unilateral temporal hypometabolism on FDG-PET without an epileptogenic lesion on MRI were compared with that of patients with unilateral temporal hypometabolism on FDG-PET with MTS on MRI (n=117).

Radioguided occult lesion localization for minimally invasive parathyroidectomy: technical consideration and feasibility.

Purpose Of The Report: Minimally invasive parathyroidectomy (MIP) constitutes one of the main surgical approaches for the patient with primary hyperparathyroidism (PHPT) caused by a single parathyroid adenoma. The purpose of the study was to investigate the feasibility of radioguided occult lesion localization (ROLL) for MIP and the potential effects of the method in histopathologic evaluation.

Materials And Methods: Twenty-two patients, diagnosed with PHPT biochemically and candidates for surgery, underwent ROLL-guided MIP (ROLL-MIP).
