Secondary chondrosarcoma of the iliac bone in a young woman – a rare case report and review of the literature

(Rzeszów University Press, 2025-06) David, Therese; Narla, Swetha Lakshmi; Subramanyan, Annapurneswari; N., Kathiresan

Introduction and aim. Chondrosarcomas are malignant cartilage-forming tumors, with secondary cases rarely arising from osteochondromas. This report presents a case of secondary chondrosarcoma developing from an undiagnosed pelvic osteo chondroma in a young female, emphasizing the importance of early detection and timely intervention. Description of the case. A 28-year-old woman with hip and back pain underwent magnetic resonance imaging, revealing a le sion in the left iliacus muscle with sacroiliac extension. Biopsy confirmed a chondroid neoplasm, and positron emission topog raphy-computed tomography showed minimal metabolic activity. Due to the extensive soft tissue component and recurrence risk, wide local excision was performed. Histology confirmed well-differentiated secondary chondrosarcoma, WHO grade 1 arising from an undiagnosed pre-existing osteochondroma. Conclusion. The described case highlights the critical role of radiological and histopathological evaluation, timely surgical in tervention, and multidisciplinary management for optimal patient outcomes.

Transient ischemic attacks – the role of arterial spin labelling

(Rzeszów University Press, 2025-06) Dinesh, Sreehari; Gupta, Dulari; Murumkar, Vivek; Gorthi, Sankar Prasad

Introduction and aim. Transient ischemic attacks are usually diagnosed by clinical criteria. Arterial spin labelling (ASL) is a noninvasive technique based on magnetic labeling of hydrogen ions in arterial blood with high sensitivity for the detection of oligemic areas in the corresponding cerebral hemisphere to the clinical phenotype. The aim is to demonstrate hypoperfusion using Arterial spin labelling techniques in TIA cases with the objective of intervening with appropriate methods to stop the stroke progression. Description of the cases. The authors analyzed 90 cases of TIA in order to ultimately select four cases of clinical TIA with Arterial spin labelling to test the proof of concept. Case 1. 47-year-old male with transient right-sided limb weakness and corresponding ASL hypoperfusion. Case 2. 57-year-old male with recurrent transient ischemic symptoms and ASL showing hypoperfusion in the right parietal lobe. Case 3. 73-year-old male with a high risk TIA and right parietal hypoperfusion on ASL that evolved into an infarct. Case 4. 30-year-old female with a sensory TIA and hypoperfusion in the right cerebral hemisphere on ASL. The hypothesis is that Arterial spin labelling will be able to demonstrate a penumbra in brain tissue in TIA cases which suggests likely progression to stroke and help in appropriate intervention to stop progression in real time. The following sequences were used during the brain MRI: diffusion-weighted imaging, fluid attenuated inversion recovery, apparent diffusion coefficient, and ASL sequences after written informed consent. Philips Ingenia 3Tesla machine obtains a 3D pseudocontinuous ASL sequence with a color coded map is obtained by Philips Ingenia 3 Tesla machine with a magnet weight of 4600 kg, 90-degree flip angle, and total duration of 3 minutes and 19 seconds. The authors present a series of 4 cases in which patients had clinical TIA and had hypoperfusion on ASL sequence correspond ing to the clinical manifestation depicting the penumbra. ASL hypoperfusion was assessed visually and cerebral blood flow (CBF) data was averaged to develop a visual CBF map. Conclusion. Arterial spin labelling is a novel marker for hypoperfusion that indicates brain parenchyma under threat due to either stenosis in vessels of the cerebral circulation or embolic phenomenon.
