Acute Peritonitis: A Mimic of Malignancy-Related Ascites in a Patient With Peritoneal Carcinomatosis.

Peritonitis, an inflammation of the peritoneal cavity, can be caused by various factors. The presence of ascites in a cancer patient is concerning for either metastasis or advanced cancer. Diagnosing acute peritonitis in a patient with cancer-related ascites can be quite challenging and often requires additional diagnostic procedures, such as paracentesis, to confirm the diagnosis and identify the exact cause of the ascites. Even with paracentesis, determining the exact cause of ascites can be a diagnostic challenge. Peritoneal carcinomatosis, with a poor survival rate, can originate from the peritoneal lining itself or result from intra-abdominal cancer, and trying to determine its origin can be difficult. We present the case of a 68-year-old female patient with a known history of cancer experiencing worsening ascites and peritonitis.

Osteitis Condensans Ilii: An Uncommon Cause of Back Pain Masquerading as an Inflammatory Spondyloarthropathy.

Osteitis condensans ilii (OCI), an uncommon cause of chronic back pain, remains a medical conundrum. The primary care physicians' limited awareness of this disease's clinical features, progression, diagnostic modality, and treatment principles creates a situation where the continuous use of numerous and sometimes unnecessary diagnostic tests leads to misdiagnosis of the etiology of chronic back pain and a rise in the cost of health care. Therefore, to further enhance the awareness of this disease, we present a case of osteitis condensans ilii masquerading as an unusual cause of chronic lower back pain in a postmenopausal female.

Fabella and patella variants: radiographic prevalence, distribution and clinical relevance in a population of black african descent.

To evaluate the radiographic characteristics and prevalence of fabella and patella variants in an indigenous African population. This retrospective observational study of orthogonal knee radiographs of 377 consecutive subjects was conducted in Lagos, Nigeria, from February 2017 to November 2017. The presence of bipartite/multipartite patella, as well as the presence of fabella were noted. The craniocaudal diameter, anteroposterior diameter, fabello-femoral distance and fabello-tibial distance of the fabella were measured. P≤0.05 represented a statistically significant result. Three hundred and seventy-seven subjects were enrolled. The average age was 41.22±21.37 years with a range of 3-100 years old. There were 158 male (41.9%) and 219 female (58.1%) subjects. The prevalence of fabella was 11.94%. There was a positive correlation between age <47 and ≥47 and occurrence of fabella, P<0.015. There was no statistically significant difference between the mean male and female measured fabella diameters. The overall prevalence of bipartite and multipartite patella in this study was 2.12%. Among male and female subjects, the difference in prevalence of bi and multipartite patella was statistically significantly, P=0.03. The prevalence of fabella and patella variants was lower in this study compared to the findings in other populations and ethnicities. Sex and age were significantly correlated with fabella prevalence. The results reported in this study will facilitate future studies examining the correlations between fabella and patella variants and various knee pathologies in a population of Black African descent.
