Osteoblastoma cervical: relato de caso

Abstract

ResumoOsteoblastoma é um tumor primário benigno raro. Constitui cerca de 3% dos tumores benignos e 1% de todos os tumores ósseos. O objetivo do tratamento é a ressecção completa, que limita o risco de recidiva. Por se tratar de um tumor vascularizado, a ressecção completa é, muitas vezes, difícil. Os autores descrevem um caso clínico de um paciente do sexo masculino de 19 anos que apresentava queixas de cervicalgia direita com irradiação para o ombro. O exame por tomografia computadorizada indicou uma lesão em C7 compatível com osteoblastoma. O paciente foi submetido a resseção cirúrgica após embolização pré-operatória e artrodese anterior. Aos 3 anos de seguimento, o paciente encontra-se assintomático e, até a data, sem evidência de recidiva.

Aggressive osteoblastoma of the cervical spine and resultant complication due to swollen oxidized regenerated cellulose: A case report

“…Typically, it involves the posterior elements of the spine. [ 12 , 15 ] While cervical spine involvement is rare, the proximity of the vertebral artery and the spinal cord makes total resection challenging. [ 1 , 5 , 15 ] In spinal osteoblastoma series, recurrence rates are between 9.7% and 15%, with incomplete resection being the primary cause.…”

“…[ 1 , 5 , 15 ] In spinal osteoblastoma series, recurrence rates are between 9.7% and 15%, with incomplete resection being the primary cause. [ 9 , 12 ] The rate of malignant transformation to osteosarcoma is around 12–25%. [ 1 , 2 , 12 , 15 , 16 ] En bloc resection is recommended for treatment, particularly in aggressive Enneking Stage 3 tumors with invasion exceeding the bone cortex.…”

[ 1 , 2 , 9 , 12 , 14 , 18 ] The most common presentation is persistent neck pain, local tenderness, and torticollis, which do not improve with nonsteroidal anti-inflammatory drugs.…”

“…[ 2 , 6 , 18 ] Osteoblastoma cases of the cervical spine are rarely reported. [ 1 , 5 , 9 , 10 , 12 , 15 ] Due to its low incidence and nonspecific symptoms during the early course, late diagnosis is highly likely. [ 9 , 12 , 15 ] If the lesion has progressed to aggressive osteoblastoma (Enneking Stage 3), en bloc resection is recommended for treatment.…”

[ 1 , 2 ] The proximity of the spinal cord, nerve roots, and vertebral artery at the cervical spine region and the highly vascular nature of aggressive osteoblastoma make total resection challenging and increase the risk of complications.…”
