Pneumoperitoneum is often associated with surgical complications or intra-abdominal sepsis. While commonly deemed a surgical emergency, pneumoperitoneum in a minority of cases does not involve a viscus perforation or require urgent surgical management; these cases of “spontaneous pneumoperitoneum” can stem from a variety of etiologies. We report a case of a 72-year-old African American male with a history of metastatic pancreatic adenocarcinoma who presented with new-onset abdominal distention and an incidentally discovered massive pneumoperitoneum with no clear source of perforation on surveillance imaging. His exam was non-peritonitic, so no surgical intervention was recommended. He was treated with bowel rest, intravenous antibiotics, and hydration. He had a relatively benign clinical course with preserved gastrointestinal function and had complete resolution of his pneumoperitoneum on imaging two months after discharge. This case highlights the importance of considering non-surgical causes of pneumoperitoneum, as well as conservative management, when approaching patients with otherwise benign abdominal exams.
Spontaneous tumor lysis syndrome is an exceedingly rare manifestation of metastatic prostate cancer. It can masquerade as thrombotic thrombocytopenic purpura (TTP) or complement-mediated hemolytic uremic syndrome (HUS). These entities present with microangiopathic hemolytic anemia, thrombocytopenia, and renal failure, and improve with the initiation of plasma exchange and steroids. In situations where the laboratory data does not wholly validate the presumed diagnosis and clinical and laboratory deterioration occurs in spite of appropriate treatment, it is necessary to expand the differential diagnosis and investigation. In this case, worsening renal function, cytopenias, lactate dehydrogenase, and uric acid in the setting of proper treatment for TTP and complement-mediated HUS prompted additional analysis. This workup revealed bone marrow infiltration by metastatic prostate cancer complicated by tumor lysis syndrome.
We present a case of bilateral lesions in a 50-year-old man, which were on first impression mistaken for and initially treated as bilateral cellulitis. We propose that bilateral cellulitis, as opposed to unilateral, is rare and that other aetiologies should be considered in evaluating a patient with bilateral lesions. The differential diagnosis includes stasis-dermatitis, lipodermatosclerosis, lymphoedema and vascular lesions such as Kaposi sarcoma, as was identified in this case. Early consultation with dermatology and biopsy in unclear cases mitigates the unnecessary use of prolonged antibiotics, antibiotic resistance andClostridium difficileinfections. HIV testing is an essential screening test in all adults who present with non-specific viral symptoms and rash.
Gastro-pleural fistula is a rare condition, and the diagnosis can be challenging, as demonstrated in our case. The management is even more complex, with wide gamut of management strategies from more conservative management such as endoscopic closures and minimally invasive video-assisted thoracoscopic surgery (VATS) to open surgical repair. We present the case of a 55-year-old female with metastatic renal cell cancer with prior radiation therapy and cabozantinib treatment who was diagnosed with gastro-pleural fistula after extensive workup. She underwent endoscopic closure and subsequent jejunostomy tube feeding, venting gastrostomy tube, and draining chest tube. Antibiotics and chest tube drainage were primary modalities for treatment of her empyema. Subsequently, she required laparoscopic surgery for fistula repair.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
