| description | •Three SISCOM patterns were seen in pediatric temporal lobe epilepsy and unilateral anterior hyperperfusion is most identified.•Type of focal cortical dysplasia and presence of hippocampal sclerosis were significant determinants of SISCOM patterns.•Lobar concordance of SISCOM and ictal and interictal scalp EEG significantly correlated with postoperative outcomes.•There was no significant correlation between SISCOM patterns and one-year postoperative outcomes.
We evaluated SISCOM patterns and their relationship with surgical outcome in children with temporal lobe epilepsy (TLE) who had undergone a temporal lobe surgery.
This was an observational study evaluating SISCOM patterns in 40 children with TLE. We classified SISCOM patterns into 4 categories; (i) unilateral anteromesial and/or anterolateral temporal pattern; (ii) unilateral anteromesial and/or anterolateral temporal plus posterior extension pattern; (iii) bilateral anteromesial and/or anterolateral temporal pattern; and (iv) atypical pattern. Determinants of SISCOM pattern and correlation between postoperative outcomes and SISCOM patterns were evaluated.
Pattern (i), (ii), (iii), and (iv) were identified in 10 (25%), 14 (35%), 0 (0%), and 16 (40%) patients, respectively. There was no significant correlation between patterns and postoperative outcomes. SISCOM patterns significantly associated with the presence of hippocampal sclerosis and type of focal cortical dysplasia (p-value = 0.048 and 0.036, respectively). Patients with HS had 5 times the odds of having unilateral temporal pattern, compared to patients with other neuropathology (OR = 5, 95% CI 0.92 to 27.08). Patients with FCD type 2 had 9.71 times the odds of having atypical pattern, compared to patients with other types of FCD (OR = 9.71, 95% CI 0.92 to 103.04). Lobar concordance of SISCOM and ictal and interictal scalp EEG significantly correlated with postoperative outcomes (p-value = 0.018 and 0.013, respectively).
Three SISCOM patterns were seen. Patients with HS had increased odds of having unilateral temporal pattern while patients with FCD type 2 had increased odds of having atypical pattern. However, there was no significant correlation between SISCOM patterns and postoperative outcomes. Lobar concordance of SISCOM and ictal and interictal scalp EEG significantly correlated with postoperative outcome.

This study shows that the distribution of SISCOM patterns and their relationship with postoperative outcomes in children with TLE are different from adult population. Besides, SISCOM may add only limited diagnostic and prognostic information in children with drug-resistant TLE undergoing epilepsy surgery. Further evaluation to identify patient populations that may benefit from SISCOM is desirable.</description><identifier>ISSN: 1525-5050</identifier><identifier>EISSN: 1525-5069</identifier><identifier>DOI: 10.1016/j.yebeh.2021.108074</identifier><language>eng</language><publisher>Elsevier Inc</publisher><subject>Children ; Outcome ; SISCOM ; Temporal lobe epilepsy</subject><ispartof>Epilepsy & behavior, 2021-08, Vol.121, p.108074-108074, Article 108074</ispartof><rights>2021 Elsevier Inc.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c336t-c187d2a73f9e229f2814b4012193694dce884c0fab744425c62f9e01430a836b3</citedby><cites>FETCH-LOGICAL-c336t-c187d2a73f9e229f2814b4012193694dce884c0fab744425c62f9e01430a836b3</cites><orcidid>0000-0003-0873-9718 ; 0000-0002-4990-5754 ; 0000-0003-1166-1245 ; 0000-0003-1431-4054 ; 0000-0002-3924-805X</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://www.sciencedirect.com/science/article/pii/S1525505021003085$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,776,780,3537,27901,27902,65534</link.rule.ids></links><search><creatorcontrib>Aungaroon, Gewalin</creatorcontrib><creatorcontrib>Trout, Andrew T.</creatorcontrib><creatorcontrib>Radhakrishnan, Rupa</creatorcontrib><creatorcontrib>Horn, Paul S.</creatorcontrib><creatorcontrib>Arya, Ravindra</creatorcontrib><creatorcontrib>Tenney, Jeffrey R.</creatorcontrib><creatorcontrib>Holland, Katherine D.</creatorcontrib><creatorcontrib>Mangano, Francesco T.</creatorcontrib><creatorcontrib>Leach, James L.</creatorcontrib><creatorcontrib>Rozhkov, Leonid</creatorcontrib><creatorcontrib>Greiner, Hansel M.</creatorcontrib><title>Subtraction ictal SPECT co-registered to MRI (SISCOM) patterns in children with temporal lobe epilepsy</title><title>Epilepsy & behavior</title><description>•Three SISCOM patterns were seen in pediatric temporal lobe epilepsy and unilateral anterior hyperperfusion is most identified.•Type of focal cortical dysplasia and presence of hippocampal sclerosis were significant determinants of SISCOM patterns.•Lobar concordance of SISCOM and ictal and interictal scalp EEG significantly correlated with postoperative outcomes.•There was no significant correlation between SISCOM patterns and one-year postoperative outcomes.
