Extradural spinalcord compression was observed in myelotomography of thethoracolumbar segment. The patient was submitted to exploratoryhemilaminectomy of T13-L1 and L1-L2, in an attempt to decompressthe medullar segments. During the surgery it was observed oneadult parasite, identified as Dioctophyma renale, located inthe extradural space and causing spinal cord compression.The patient was submitted to postoperative physical therapy,presenting clinical improvement 15 days after surgery, remainingon prone position and able to move the pelvic limbs, but not yetable to walk unassisted. It started walking naturally 60 days afterthe surgery. With the present clinical report, the erratic migrationof the parasite Dioctophyma renale should be added to thelist of differential diagnoses for patients with paraparesis andextramedullary lesion pattern, especially in endemic areas.RESUMO Uma cadela errante, com 16kg de peso eaproximadamente 4 anos de idade foi submetida ao exame fisicopor demonstrar deficit de locomocao dos membros pelvicos. Amielotomografia revelou compressao extradural da medulaespinhal, no segmento toracolombar. A paciente foi submetida auma hemilaminectomia exploratoria T13-L1 e L1-L2, na tentativade descompressao do segmento mencionado. Durante a cirurgia,foi observado um parasita nematodeo adulto, identificado comoDioctophyma renale, localizado no espaco extradural e causandocompressao medular. Instituida fisioterapia pos-operatoria, acadela apresentou melhora clinica apos 15 dias do procedimentocirurgico, mantendo-se em estacao com capacidade paramovimentar os membros pelvicos e passou a caminhar 60 diasapos a cirurgia. Dessa forma, pode-se considerar a migracaoerratica de Dioctophyma renale como diagnostico diferencialpara pacientes com paraparesia e padrao de lesao extramedular,especialmente em regioes nas quais a parasitose seja endemica.

Extrusions in cranial thoracic region are rare, and there is few cases in literature reporting this situations,this rarity is attributed to the presence of the intercapital ligament connecting the rib heads between T2 and T10, whichstrengthens this region both mechanically and anatomically. The aim of this article is report the clinical signs, diagnosisand treatment of a case of Type I Hansen IVDD between T8 and T9 in a Dachshund breed dog. Case: An 8-year-old Dachshund male dog was presented for investigation of pelvic limb incoordination and back pain,which started 10 days prior to the consultation. It had a history of a similar condition 3 months earlier that showed improvementafter clinical treatment. On neurological examination was identified in both pelvic limbs proprioceptive ataxia,absence of proprioception, increased muscle tone, presence of interdigital reflex and increased patellar reflex. Cutaneoustrunci reflex was absent below T11 on the left side, and pain was noted upon palpation of T7 through the T12 vertebrae.A grade II asymmetric thoracolumbar lesion with hyperesthesia was diagnosed. On suspicion of IVDD, cerebrospinalfluid (CSF) collection and CT
