Abstract Background Osteochondromas are a benign outgrowth of bone and cartilage and one of the most common bone tumors that usually occur in long bones, with only 1–4% being located in the spine, more frequently in the cervical and upper dorsal region, and rarely the lumbar spine. Here, we report a case of lumbar spine (L5) osteochondroma arising from the neural arch. Case presentation A 30-year-old man presenting with a solid painless mass at the lower lumbar region. No neurological symptoms. Radiological examinations revealed an exophytic lesion in the fifth lumbar articular process, and the spinous process appears to be a solitary osteochondroma. Lumbar spine magnetic resonance imaging showed a bony lesion covered by a 2-mm-thick cartilaginous cap. Surgical en bloc resection of the mass was performed, and the histopathological examination confirmed the diagnosis of osteochondroma. No evidence of recurrence at the end of 4-year follow-up. Conclusion Osteochondromas are benign tumors rarely present in the spine; diagnosis can be made by the typical appearance of the cartilaginous cap over the mass in the magnetic resonance imaging. Surgical excision is the best management option.

Abstract OBJECTIVE AND IMPORTANCE: Hemangiopericytoma is a rare tumor of the central nervous system, most often found supratentorially. Thirty-nine cases within the spinal column, of which five were intradural, have been reported. To date, no magnetic resonance imaging descriptions of intradural hemangiopericytomas have been published. This article is the first report of an intradural hemangiopericytoma of the lumbar spine and the first magnetic resonance imaging description of such a lesion. CLINICAL PRESENTATION: A 31-year-old man presented with progressive bilateral leg paresthesia and increased lower extremity cramping and fatigue during a period of several months. This progressed to urinary urgency, frequency, and sexual dysfunction. A neurological examination revealed no motor or sensory deficits. Gadolinium-enhanced magnetic resonance imaging of the lumbar spine revealed a centrally located intradural mass posterior to the L4 vertebral body. TECHNIQUE: The patient underwent a laminectomy of L4 and partial laminectomy of L3 with complete en bloc resection of the tumor. A discrete, intradural, red-appearing lesion was found and resected en bloc. Pathological findings were consistent with hemangiopericytoma. CONCLUSION: Intradural hemangiopericytomas, although rare, cannot be differentiated from other, more benign tumors. Spinal hemangiopericytomas ideally should be resected en bloc to reduce operative blood loss and potentially increase disease-free survival time. Despite total surgical resection of these benign-seeming lesions, the high recurrence rate mandates close follow-up and consideration of adjuvant therapy.

Objective: To determine the diagnostic accuracy of magnetic resonance imaging in diagnosing bone tumorskeeping histopathological as correlation gold standard. Study Design: Descriptive cross-sectional study. Place and Duration of Study: Departments of Radiology, Orthopedics and Pathology of Pakistan Institute ofMedical Sciences, Islamabad, from Jan 2018 to Jan 2019. Methodology: All the patients who had complain of bone deformity or pain with high suspicion of neoplasticpathology involving bone and soft tissue on radiograph were included in study. Patients were first diagnosed on conventional radiography followed by magnetic resonance imaging. Magnetic resonance imaging with contrast was done on Phillips 1.5 tesla machine. T1W, T2W, STIR images, Fat suppressed, PD spair and post contrast T1W images were obtained. Positive magnetic resonance imaging findings which were noted were; marrow involvement, cortical break, soft tissue involvement, joint involvement, neurovascular bundle involvement and post contrast enhancement on T1W imaging. Then bone biopsy was performed. The removed bone was sent for histopathological examination in all cases. The histopathological reports were collected. The results were entered in structured proformas. Data was collected after the informed consent. All the data was entered and analyzed using SPSS version-23. Results: Fifty patients of both genders were recruited during our study duration. 32 (64.0%) were male while 18(36.0%) were female patients. Mean age of the patient was 54.5 ± 14.3 years with range 18 to 80 years. Among the benign tumors vertebral hemangiomas were most commonly found 5 (10.0%) followed by osteochondroma which was 4 (8.0%), while among malignant........

Background:The incidence of inflammatory and structural lesions on magnetic resonance imaging of sacroiliac joints (MRI SIJs) in patients with hypermobility related disorders has not been fully investigated. Hypermobile patients are more susceptible to pelvic instability and biomechanical stress of the SIJs, leading to MRI SIJ changes similar to those occurring in spondyloarthritis (SpA). Patients with hypermobility and suspected SpA pose a unique challenge owing to the high prevalence of back pain in the hypermobility cohort and the absence of spinal restriction on clinical examination.Objectives:In this study, we aim to investigate the incidence of MRI SIJ lesions in patients with hypermobility.Methods:We performed a retrospective study of all patients with a confirmed diagnosis of hypermobility related disorders (including hypermobility syndrome, hypermobility spectrum disorders and Ehlers-Danlos Syndromes) referred for an MRI lumbar spine and SIJ between 2011 and 2019 to investigate long-standing back pain. MRIs were examined by a musculoskeletal (MSK) radiologist with more than 25 years of experience, who was blinded to the clinical outcome of the patients. MRI SIJs were assessed for the presence of bone marrow oedema, subchondral sclerosis, erosion, fatty change, enthesitis, ankylosis, joint fluid and capsulitis.Results:51 patients with confirmed hypermobility related disorders were referred for MRI SIJ and lumbar spine between 2011 and 2019. 3 patients demonstrated clinical features in keeping with a diagnosis of SpA and were excluded from the study. 15/48 (31.3%) of patients with hypermobility and back pain (but no clinical picture of SpA) were found to have inflammatory and/or structural lesions on MRI SIJ. The most frequent lesions were small foci of bone marrow oedema (16.6%) followed by subchondral sclerosis (12.5%) and fatty change (10.4%). The incidence of erosions was 4.2%.Conclusion:There is a relatively high incidence of inflammatory and structural lesions on MRI SIJ of patients with hypermobility. The presence of hypermobility should be taken into consideration when interpreting MRI changes in patients with suspected SpA. Further research into long-term outcomes of MRI SIJs in patients with hypermobility and back pain is required to establish the clinical significance of these findings.Disclosure of Interests: :Alexis Jones: None declared, Coziana Ciurtin Grant/research support from: Pfizer, Consultant of: Roche, Modern Biosciences, Hanadi Kazkaz: None declared, Margaret Hall-Craggs: None declared

Primary intracerebral manifestation of multiple myeloma is rare and usually arises from the meninges or brain parenchyma. The authors present a case of multiple myeloma primarily manifesting within the lateral ventricle. A 67-year-old man was admitted with headache accompanied by slowly progressing right hemiparesis. Magnetic resonance imaging showed a large homogeneous contrast-enhancing intraventricular midline mass and hydrocephalus. The tumor was completely resected, and histopathological examination revealed plasmacytoma. After postoperative radio- and chemotherapy, vertebral osteolysis was detected as a secondary manifestation of multiple myeloma.

AbstractObjective:To assess the efficacy of excision of nasal dermoids through a closed rhinoplasty incision. This is the first description of the use of this approach for excision of superficial nasal dermoids.Methods:Three boys aged five, nine and 12 years presented with midline nasal dermoids with minimal cutaneous involvement. Magnetic resonance imaging demonstrated distinct, cystic, superficial nasal masses. The cysts were excised through a closed rhinoplasty approach. In each case, completeness of extirpation was judged by histopathological examination of the excised specimen. Aesthetic outcome was recorded photographically.Results:All three patients' cysts were completely excised, with excellent cosmetic results.Conclusions:The closed rhinoplasty incision is another approach in the surgeon's armamentarium for excision of small, superficial nasal dermoid cysts. In well selected cases, this approach gives optimal cosmetic results, provides adequate exposure with minimal dissection, and allows total extirpation.
