Aggregomas are rare localized masses of monoclonal nonamyloid immunoglobulin light-chain deposits. To date, there have been only a few reports of isolated aggregomas, with the majority detailing renal, lymph node and brain deposition. We present a rare case of paraspinal aggregoma in a 67-year-old female who presented with a complaint of cough and chest pain. Imaging demonstrated a left-sided paravertebral mass extending from T7-T10. Pathological analysis showed lamellar deposition of extracellular eosinophilic material with an associated lymphoplasmacytic nonamyloid infiltrate. To our knowledge, this is the first report of a paraspinal aggregoma. While exceedingly rare, this tumor can be included in the radiologic differential diagnosis of paravertebral soft tissue tumors in adults. The observation of our case adds to the limited understanding of the etiology, pathogenesis, natural history, and treatment of nonamyloid light-chain depositions. |
