Edema of the psoas major muscle can indicate various pathologies, such as infection, malignancy, and trauma, but it can also result from benign causes like delayed-onset muscle soreness (DOMS). This article presents the case of a 44-year-old female patient who developed DOMS in the psoas major after participating in an intense abdominal workout. The patient reported hip pain that began a day after the workout, which was confirmed by magnetic resonance imaging (MRI) revealing significant edema in the psoas major muscles, particularly on the right side. Conservative treatment with rest and analgesics led to full recovery within two weeks. DOMS, typically associated with eccentric exercises, can be mistaken for more serious conditions, but its recognition is crucial to avoid unnecessary investigations and interventions. This case highlights the importance of clinical history and imaging findings in distinguishing DOMS from other causes of muscle edema, emphasizing the need for accurate diagnosis to ensure appropriate management.

Sarcopenia is an independent risk factor for morbidity and mortality in patients suffering from small cell lung cancer (SCLC), however, a universal indicator of sarcopenia usable in clinical practice is still missing. A novel indicator for describing the severity of cancer could be helpful in tailoring the anti-tumor therapy. The aim of this study was to evaluate the computed tomography (CT) scans of total muscle area and radiation attenuation in patients suffering from small cell lung cancer. We used staging CT scans performed at the time of diagnosis to measure total muscle area (TMA) and average psoas density (PD) at level of the 3rd lumbar vertebra. TMA and PD were statistically evaluated in association with overall survival and disease staging. We used Mann-Whitney test and Spearman ́s correlation coefficient for statistical testing and p-value under 0.05 was considered statistically significant. Retrospectively we examined 47 patients suffering from SCLC (mean age 65.05+/-7.3 years, BMI 23.97+/-4.4 kg/m2, BSA 1.77+/-0.2 m2, 30-day mortality was 4.3 % with 10 months median survival). As sarcopenia was pointed TMA under 55 and 39 cm2/m2 for men and women respectively. The sarcopenic patients had significantly shorter median survival (7 vs. 11 months, p=0.05). We observed a significant relationship between survival and performance status (Spearman ́s correlation, R=-0.39, p=0.05). The patients were divided into two groups according to the extensive (ED, n=34) or limited (LD, n=13) form of the disease. We observed significant difference in PD (42.49+/-6.1 vs. 47.67+/-4.5 HU, p=0.006) between ED vs. LD groups.
