Abstract
Cíl. Prezentovat scintigrafický SPECT a hybridní SPECT/low dose CT obraz mnohočetných lymfangiomů ve slezině u 35leté mladé ženy s anamnézou idiopatické trombocytopenické purpury a ukázat na tuto poměrně vzácnou příčinu mnohočetných fotopenických ložisek ve slezině. Vzhledem k tomu, že pacientka dále také měla mnohočetné lymfangiomy v Th, L páteři, jednalo se o obraz lymfangiomatózy. Materiál a metoda. Pacientka vyhledala lékaře pro hmatnou rezistenci v levém podžebří a několik týdnů trvající bolesti. Na CT se zobrazila zvětšená slezina prostoupená mnohočetnými cystami. V hilu sleziny se zobrazilo ovoidní ložisko o průměru 15 mm. Bylo pomýšleno na akcesorní slezinu. Vzhledem k podezření na akcesorní slezinu (splenunkulu) u pacientky s anamnézou idiopatické trombocytopenické purpury následovala před zvažovanou splenektomií statická scintigrafie sleziny s 99mTc-Sn-koloidem doplněná o hybridní SPECT/low dose CT jater a sleziny. Výsledky. Scintigrafie a SPECT zobrazil zvětšenou slezinu s mnohočetnými fotopenickými ložisky, které se na hybridním SPECT/low dose CT obrazu promítaly do popisovaných cystických ložisek. Nález ze scintigrafie byl kompatibilní s diagnózou mnohočetných lymfangiomů. Splenunkula se na scintigrafii a SPECT nezobrazila. Vzhledem ke klinickým obtížím pacientka podstoupila laparoskopickou splenektomií. Histologické vyšetření potvrdilo diagnózu mnoho četných lymfangiomů. Závěr. Scintigrafie sleziny doplněná o hybridní SPECT/low dose CT vyloučila přítomnost splenunkuly a zobrazila mnohočetné lymfangiomy Hybridní SPECT/low dose CT upřesnilo prostorovou lokalizaci fotopenických lézí a jejich počet.
Aim. To present scintigraphy, SPECT and SPECT/low dose CT images of multiple spleen lymphangiomas in 35-years-old woman with history of the idiopathic thrombocytopenic purpura and multiple lymfangiomas in the Th and L vertebrae. Method. The woman was examined for a palpable resistance and a few weeks persisting pain in the left epigastrium. The abdomen CT detected the enlarged spleen with multiple cysts. The ovoid formation (diameter 15 mm) in the spleen hilus was imaged. It was given a thought to accessory spleen in a patient with positive history of the idiopathic thrombocytopenic purpura. The static spleen scintigraphy with 99mTc-Sn-colloid was performed before splenectomy The spleen SPECT and SPECT/low dose CT was added to improve sensitivity of the examination. The double-head multi-imaging SPECT/low dose CT scanner with large field of view was used. The scanner was fitted with low-energy parallel collimators with infra-red body contouring and a high resolution. Results. The scintigraphy and SPECT imaged multiple spleen photopenic lesions which were fused to cystic spleen lesion on the SPECT/low dose CT. The finding was compatible with diagnosis multiple lymfangiomas in spleen. No accessory spleen was detected in spleen hilus by means of scintigraphy and SPECT. The woman underwent laparoscopic splenectomy and diagnosis of multiple spleen lymphangiomas was confirmed. Conclusion. The scintigraphy and SPECT excluded accessory spleen in the spleen hilus and images multiple photopenic lymfangiomas in the spleen. The hybrid SPECT/low dose CT put more precisely the space localization of the photopenic/cystic lesions and their number.
