STUDY DESIGN: Prospective clinical study. PURPOSE: The purpose of this study was to evaluate the effect of interlaminar fusion and short segment pedicle screw fixation on thoracolumbar vertebral injuries for preventing pain and post-traumatic kyphosis. OVERVIEW OF LITERATURE: The treatment of thoracolumbar injuries continues to be one of the most controversial areas in spine care. The main aim of surgical treatment is to decompress the spinal cord or nerve roots, realign the spine, and correct or prevent post-traumatic kyphosis. We evaluated the outcome of interlaminar fusion along with posterior decompression and short segment pedicle screw fixation in patients with thoracolumbar fractures with neurological deficit. METHODS: Twenty-two patients with traumatic thoracolumbar vertebral injuries and neurological deficit underwent short segment pedicle screw fixation above and below the fractured vertebrae, posterior decompression, and interlaminar fusion using a bone graft. RESULTS: All patients were followed up for 12 months postoperatively. The average operative time and blood loss was 142 minutes and 214 mL, respectively. Of the 22 patients, 14 recovered completely. Of the nine patients with American Spinal Injury Association (ASIA) grade A disease, two improved by 1 grade, whereas one each improved by grades 2, 3, and 4, and four did not recover. Radiologically, vertebral kyphosis angle improved from 20.91 preoperatively to 15.73 postoperatively, sagittal index improved from 24.77 to 18.73, the sagittal plane kyphosis angle improved from 17.45 to 11.41, regional angle kyphosis improved from 14.73 to 10.14, the superior inferior end plate angle from 16.14 to 13.00, and mean anterior body compression improved from 36.26 to 27.64 postoperatively. No implant failed and no patient had neurological deterioration. CONCLUSIONS: Short segment pedicle screw fixation with posterior decompression and interlaminar fusion provided considerable reduction in kyphosis, restored the vertebral height of patients with thoracolumbar vertebral injuries and neurological deficit, and prevented development of delayed kyphotic deformity.

Pulmonary blastoma (PB) is a rare thoracic malignancy and preoperative diagnosis is challenging. A young man presented with dyspnea and chest pain for 3–4 months and chest-computed tomography (CT) revealed large mass in the left lung upper lobe and pleural effusion. Repeated CT-guided fine-needle aspiration cytology from the lesion and pleural fluid aspiration was negative for malignancy. F-18-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) revealed heterogeneous tracer avidity in left lung mass with areas of necrosis. Real-time PET-CT-guided biopsy from metabolically active component of the lesion revealed biphasic PB on histopathology.

Tuberculosis (TB) occurring after a closed bone fracture in the patient with no history of TB and no evidence of TB infection at the time of initial fracture is a rare entity. We report one such case of a 48-year-old female, who presented in the emergency department with an olecranon fracture which was open reduced and internally fixed with tension band wiring. Patient presented in the outpatient department with serosanguineous discharge at 3 weeks after surgery. The discharge was sent for culture and sensitivity tests, and the patient was managed by antibiotics and daily dressings. There was wound dehiscence and the underlying implant was exposed, which was removed at 12 weeks after surgery. Repeat debridements and dressings continued for 6 months, but the discharge from the wound site continued. X-rays of the elbow performed at 6 months raised the suspicion of TB, which was confirmed by Ziel-Neelsen staining and histopathological examination of the debrided tissue. Following the confirmation, patient was put on antitubercular drugs. The patient responded to antitubercular drug therapy (ATT), the purulent discharge from the wound ceased, and eventually the wound healed after 2 months of starting ATT.

Somatostatin receptor (SSTR)-based imaging and therapy has emerged as well-established modality in neuroendocrine tumors. However, its role in inflammation imaging is still evolving. We present a 48-year-old male with metastatic neuroendocrine tumor who underwent lutetium-177-based somatostatin receptor-based therapy. The post-therapy scan showed a focal tracer uptake in the left calf muscle in addition to the expected tracer uptake at the primary and metastatic sites. Further, cross-sectional imaging and biochemical investigations revealed peripheral vascular disease (PVD). The incidental tracer uptake in the calf on post-therapy scan potentiates the role of somatostatin receptor scintigraphy in identifying macrophagespecific inflammatory reactions.

Hodgkin’s lymphoma most commonly presents as painless lymphadenopathy and systemic B symptoms like fever, night sweats, and weight loss. But rarely, it can present with unusual paraneoplastic manifestations. In the present case, we report a 30-year-old woman who presented with sub-acute onset pan-cerebellar symptoms. The serum neuronal antibody panel was negative. She underwent F-18 FDG PET/CT to evaluate the neoplastic etiology as the underlying cause, which demonstrated both the primary etiology and the paraneoplastic changes in the brain.

Purpose: To assess the utility of convoluted neural network (CNN) in differentiating clinically significant and insignificant prostate cancer in patients with 68Ga PSMA PET/CT-targeted prostate biopsy-proven prostate cancer. Methods: In this retrospective study, 142 patients with clinical suspicion of prostate cancer were evaluated who underwent 68Ga-PSMA PET/CT imaging followed by 68Ga-PSMA PET/CT-targeted prostate biopsy from the PSMA-avid prostatelesion. Twenty patients with no PSMA-avid lesions were excluded. Local Image Features Extraction (LifeX) software was used to extract radiomic features (RF) from delayed 68Ga-PSMA PET/CT images of 122 patients. LifeX failed to extract radiomic features in 24 patients, and the remaining 98 were evaluated. RFs were fed to an in-built CNN of the software for computation and results were achieved. Patients with Gleason Score ≥ 7 on histopathology were labeled clinically significant prostate cancer (csPCa). The diagnostic values of radiomic features were evaluated. Results: The csPCa was revealed in 69/98 (70.4%) patients, and insignificant PCa was noticed in 29/98 (29.6%) patients. The software extracted 124 RF from the delayed 68Ga-PSMA PET/CT images. The accuracy of the CNN was 80.7% to differentiate clinically significant and clinically insignificant prostate cancer, with an error percentage (E %) of 19.3%. The sensitivity, specificity, positive predictive, and negative predictive values were 90.3%, 57.7%, 83.6%, and 71.4%, respectively, to detect csPCa. Conclusion CNN is a feasible pre-biopsy screening tool for identifying clinically significant prostate cancer and can be used as an adjunct in the initial diagnosis and early treatment planning.

We present a case of papillary thyroid cancer (post-thyroidectomy status) on regular treatment with suppressive Levothyroxine therapy. On follow-up at 6 months after radioactive iodine ablation for remnant thyroid tissue, her thyroglobulin, and anti-thyroglobulin levels were 0.06 ng/ml and 670 IU/ml, respectively. Low-dose whole-body I-131 scan was negative. To look for the cause of isolated increased anti-thyroglobulin level, a whole-body ¹⁸F-FDG PET/CT was done which revealed multiple FDG-avid lytic skeletal lesions suggestive of metastases. For confirmation of diagnosis, ¹⁸F-FDG PET/CT-guided metabolic biopsy was done, which revealed Langerhans' cell histiocytosis on histopathological examination.
