Abstract
Neuroradiological examinations are important in the diagnosis of Rasmussen’s syndrome (RS), but they frequently result normal in the early phase of the disease. We performed Tc 99m HMPAO SPECT (single photon emission computed tomography) on an 11-year, 5-month-old, right-handed girl, two months since the first seizure. SPECT showed a reduced uptake of HMPAO in the left temporal region despite normal results with magnetic resonance imaging (MRI). After six months, she developed epilepsia partialis continua, neurological signs appeared, and MRI showed cortical atrophy on the left side.
SPECT seems to be a useful, inexpensive and diffuse technology able to give information in the early phases of RS useful in the prevention of serious consequences of the disease within a medical therapeutic program (ganciclovir or intravenous immunoglobulins).
Sommario
È noto che le indagini neuroradiologiche sono importanti nella diagnosi della syndrome di Rasmussen (RS), ma è altrettanto veto che esse risultano spesso normali nelle fasi precoci della malattia. Descriviamo il caso di una paziente di undici anni e cinque mesi, affetta da RS, che è stata sottoposta a Tc 99m HMPAO SPECT due mesi dopo la prima crisi. La SPECT ha mostrato una riduzione della perfusione che interessava il lobo temporale sn, mentre la risonanza magnetica (RMN) risultana normale. Sei mesi più tardi la paziente sviluppava un’epilessia parziale continua e la RMN mostrava una atrofia corticale emisferica sn. Pensiamo che la SPECT sia un esame utile, economico e di largo impiego in grado di fornire ulteriori informazioni, rispetto a quelle già descritte, sulle fasi iniziali della RS. L’individuazione precoce di una RS permette infatti di instaurare una terapia medica (ganciclovir o immunoglobuline) prima della comparsa delle gravi conseguenze della malattia.
