Clinical Significance of Incidental Focal 18 F-FDG Uptake in the Spinal Cord of Patients with Cancer

Abstract

              <span> 
                </span><h3>Purpose</h3> 
                <p>We investigated the incidence, location, and clinical significance of focal <sup>18</sup>F-FDG uptake of the spinal cord in patients with cancer.</p> 

              <span> 
                </span><h3>Methods</h3> 
                <p>We reviewed the medical records of 22,937 consecutive adult patients with known or suspicious malignancy who underwent <sup>18</sup>F-FDG PET/CT. PET/CT scans with incidental focal spinal cord uptake were selected and retrospectively reviewed to determine the presence, location, number, and maximum standardized uptake value (SUV<sub>max</sub>) of any focal hypermetabolic lesions of the spinal cord. In subjects with focal spinal uptake, clinical characteristics and clinical follow-up results, including follow-up PET/CT, were reviewed.</p> 

              <span> 
                </span><h3>Results</h3> 
                <p>Incidental focal spinal cord uptake was observed in 69 of 22,937 adult patients (incidence = 0.3%; M:F = 31:38; age, 55.8 ± 14.7 years). Seventy-eight focal hypermetabolic lesions on spinal cord in the PET/CT scans of the 69 study subjects were analyzed. The most common sites of focal spinal cord uptake were the T12 vertebra (47/78; 60.3%) and L1 vertebra (20/78; 25.6%). Multifocal cord uptake was found in 8 of 69 patients (11.6%). The average SUV<sub>max</sub> for cord uptake was 2.5 ± 0.5 (range, 1.4∼3.9). There was no clinical or imaging evidence of abnormalities in the spinal cord, both at the time of PET/CT and during clinical follow-up.</p> 

              <span> 
                </span><h3>Conclusions</h3> 
                <p>Although incidental focal <sup>18</sup>F-FDG uptake of the spinal cord is rare in patients with cancer, it may be physiological or benign, but it should not be considered as malignant involvement. Common sites for the uptake were in the T12 and L1 spine levels.</p>

Usefulness of Tc-99m Pertechnetate SPECT/CT in the Diagnosis of Testicular Infarction After Inguinal Herniorrhaphy

Abstract

              <p>A 77-year-old male underwent open repair for a right indirect inguinal hernia and complained of right scrotal pain on the third postoperative day. Color Doppler imaging revealed decreased blood flow with heterogeneous hypoechogenicity in the right testis. A Tc-99m pertechnetate testicular scan showed diffuse hyperemia and increased uptake in the right scrotum. Additional SPECT/CT revealed a photon defect in the right testicle with increased uptake in the peri-testicular area. A subsequent operation revealed a large hematoma in the right spermatic cord and consequent right testicular infarction, and right orchiectomy was performed.</p><br /><br />

Immediate liposuction could shorten the time for endoscopic axillary lymphadenectomy in breast cancer patients

Abstract

                <span> 
                  </span><h3>Background</h3> 
                  <p>Endoscopic axillary lymphadenectomy (EALND) was introduced to clinical work to reduce side effects of conventional axillary lymphadenectomy, while the lipolysis and liposuction of EALND made the process consume more time. The aim of the study was to determine whether immediate liposuction after tumescent solution injection to the axilla could shorten the total time of EALND.</p> 

                <span> 
                  </span><h3>Methods</h3> 
                  <p>Fifty-nine patients were enrolled in the study, 30 of them received EALND with traditional liposuction method (TLM), and the rest 29 patients received EALND with immediate liposuction method (ILM). The operation time, cosmetic result, drainage amount, and hospitalization time of the two groups were compared.</p> 

                <span> 
                  </span><h3>Results</h3> 
                  <p>The median EALND operation time of TLM group and ILM group were 68 and 46 min, respectively, the difference was significant (<em>P</em> &lt; 0.05); the median cosmetic results of the two groups were 6.6 and 6.4, respectively; the median drainage amount of the two groups were 366 and 385 ml, respectively; the hospitalization time of the two groups were 15 and 16 days, respectively. For the last three measures, no significant difference was confirmed (<em>P</em> &gt; 0.05).</p> 

                <span> 
                  </span><h3>Conclusions</h3> 
                  <p>Our work suggests immediate liposuction could shorten the endoscopic axillary lymphadenectomy process, and this method would not compromise the operation results. However, due to the limitations of the research, more work needs to be done to prove the availability and feasibility of immediate liposuction.</p>
