Classic central nervous system Hodgkin lymphoma masquerading as left sphenoid wing meningioma- A case report.

INTRODUCTION AND IMPORTANCE: Classic Hodgkin Lymphoma with an incidence of 2-3 cases per 100,000 population affects the Central Nervous System in 0.02 % of cases (Gerstner et al., 2008; Brice et al., 2021; Morawa et al., 2007). CNS lymphoma, contributing to 0.22 % of Central Nervous System tumors, is the uncommon extra-nodal manifestation of Hodgkin's Disease (Brice et al., 2021; Henkenberens et al., 2014). It affects the nervous system secondary to systemic lymphoma or the relapse of the disease (Gerstner et al., 2008). Only 17 cases of CNS lymphoma are reported which were limited to the CNS at the time of diagnosis (Paul et al., 2017). Only two cases of Dural-Based Hodgkin Lymphoma were reported in the literature (Paul et al., 2017). CASE PRESENTATION: We are reporting the third case of dural-attached extra-axial secondary CNS Hodgkin Lymphoma in a 33 years old female, which appeared and was operated as Left Sphenoid Wing Meningioma. CLINICAL DISCUSSION: Only 17 cases of CNS lymphoma are reported which were limited to the CNS at the time of diagnosis (Paul et al., 2017). Only two cases of Dural-Based Hodgkin Lymphoma were reported in the literature (Paul et al., 2017). Our case consists the third case of dural attached Classic CNS Hodgkin lymphoma and the first case of Classic CNS Hodgkin Lymphoma locating in the Sphenoid Wing. CONCLUSION: It is important to differentiate CNS Hodgkin Lymphoma from other types of brain tumors especially when it resides in an unusual location because the treatment of CNS Hodgkin Lymphoma is mainly combined chemo-radiotherapy than surgical intervention.

Upper Thoracic Spine (D2-D3) Fracture With Unilateral Lock Facets Without Associated Neurological Deficits: Case Report & Literature Review.

Introduction: Upper thoracic spine fractures are rare as compared to other spine segments due to anatomical landmarks. If they occur, they are usually associated with paraplegia or any other neurological dysfunction. We report upper thoracic fracture without neurological dysfunction which is a rare entity along with its radiological imaging, and management plan. Case Description: Forty-years old male presented after RTA. CT spine showed T2 vertebral body fracture with dislocation/locking of the right T2-T3 facet joint. The patient underwent surgical fixation and was neurologically intact. Conclusion: Upper thoracic spine fracture is a rare entity due to its anatomical location. And sometimes it is missed as well. Proper imaging should be considered if there is high suspicion and early surgery is warranted to prevent permanent damage.

Delayed cervical spine metastasis from intracranial solitary fibrous tumor.

Cervical spine metastasis from primary intracranial solitary fibrous tumors (SFTs) is an extremely rare clinical entity. This report focuses on its metastatic tendency, radiological imaging, management plan, and follow-up strategies in view of its long latency period for metastasis. A 35-year-old female presented with right-side cervical radiculopathy. Magnetic resonance imaging spine showed C7 vertebral body collapse with retropulsion and neural compression. Two years ago, the patient had surgical resection of intracranial SFT (World Health Organization grade 3) with no evidence of recurrence on follow-up imaging. Cervical C7 metastasis has been decompressed and fused by the anterior cervical approach. Histopathology confirmed SFT metastasis to the spine, and the patient received adjuvant radiotherapy. Cervical metastasis from well-controlled primary intracranial SFT poses a significant challenge for its diagnostic and management planning. Serial pre-emptive surveillance is warranted with regular imaging and appropriate patient counseling.

Waldenström macroglobulinemia: a review of pathogenesis, current treatment, and future prospects.

Waldenström macroglobulinemia (WM) is a chronic B-cell lymphoproliferative disorder characterized by lymphoplasmacytic cell overgrowth in the bone marrow and increased secretion of IgM immunoglobulins into the serum. Patients with WM have a variety of clinical outcomes, including long-term survival but inevitable recurrence. Recent advances in disease knowledge, including molecular and genetic principles with the discovery of MYD88 and CXCR4 mutations, have rapidly increased patient-tolerable treatment options. WM patients may benefit from chemotherapy regimens that include rituximab-based regimens, alkylating drugs, proteasome inhibitors, monoclonal antibodies, and drugs targeting Bruton tyrosine kinase inhibitors. In light of these advancements, patients can now receive treatment customized to their specific clinical characteristics, focusing on enhancing the depth and durability of their response while limiting the adverse effects. Despite the rapidly developing therapeutic armament against WM, a lack of high-quality evidence from extensive phase 3 trials remains a significant challenge in the research. We believe clinical outcomes will keep improving when new medicines are introduced while preserving efficacy and minimizing toxicity.

Diagnostic Yield of Ultrasound-guided Trucut Biopsy in Diagnosis of Peripheral Lung Malignancies.

Introduction While computed tomography (CT) guided lung biopsy has been standard in histological diagnosis of pulmonary lesions, its use is limited to the interventional radiologists only. Ultrasound (US) guided biopsy of pulmonary lesions, which can be performed in-clinic by the pulmonologists only, is becoming a more popular technique. It also has the edge of real-time techniques, multi-planar imaging, and no radiation exposure to the patients. Methods This is a retrospective review of all the patients presenting with pleural-based lung lesions who underwent US-guided biopsy for diagnosis in the Department of Pulmonology, Liaquat University of Medical and Health Sciences Hospital, Hyderabad, Pakistan from 1st January 2013 till 31st December 2017. The diagnostic yield, sensitivity, specificity, and accuracy of US-guided biopsies were evaluated for diagnoses of peripheral lung malignancies. Results Ultrasound-guided biopsies for lung lesions has a diagnostic yield of 88.3%, sensitivity of 95.80%, and specificity of 90% with an accuracy of 95.35%. Pneumothorax as an immediate complication was seen only in 1.5% cases. Conclusion US-guided biopsies are a much safer diagnostic alternative to CT-guided biopsy for lung lesions and have high diagnostic yield. It doesn't require special radiological interventionists, can be performed at patients' bedsides, and the equipment is not as expensive.
