ABSTRACT
Portal pneumatosis has been considered an ominous sign associated with intestinal ischemia, with a mortality rate of up to 90% as long as it is associated with sepsis. However, the prognosis of mesenteric ischemia depends on the etiology rather than the presence of portal pneumatosis. We present a patient with portal pneumatosis that disappeared 24 hours after the first surgery, but irreversible ischemic lesions were established in the terminal ileum. It should be noted that the excretion of the intravenous contrast is mainly through the kidneys, and it can be eliminated through alternative routes such as the bile duct or the mucosa of the small intestine (vicariant excretion), especially in patients with renal pathology.

Gastric schwannoma can be malignant in 13.8% of cases. The prognosis of malignant schwannoma is usually poor, characterized by a rapidly progressive disease course and a poor response to chemotherapy. Normally, the recurrence of schwannoma is due to involvement of the surgical resection margin. In turn, recurrence of malignant gastric schwannoma GS is approximately 50%, 25% locoregional and 25% with liver metastases. Even after a complete gastric resection with associated lymphadenectomy, schwannoma may present liver metastases during follow-up.

Pulmonary Tuberculosis (TB) has increased in Spain in recent years due to multiple factors. Peritoneal tuberculosis represents the sixth cause of extrapulmonary tuberculosis, accounting for 11% of tuberculosis cases. We report a 28-year-old male from Mali, who arrived at our hospital with an acute abdomen due to intestinal perforation with a computed tomography scan (CT) performed peritoneal tuberculosis mimicking primary carcinomatosis. This presents a diagnostic and therapeutic challenge, since the surgical approach differs in both cases, and the prognosis is very different between them.

Although morphology is the key to histological diagnosis, gastric mesenchymal tumors can share very similar growth and cellularity patterns, sometimes being indistinguishable. Therefore, immunohistochemical techniques are going to be crucial in the definitive diagnosis. The objective of this work is to perform an immunohistochemical differential diagnosis of gastric mesenchymal tumors.

A 39-year-old patient consulted for an incidental finding of a mesenteric-epiploic mass measuring 11x6x9.5 cm. Laparoscopic excision of the lesion and cholecystectomy were indicated, revealing a myolipomatous mesenchymal neoplasm in the hepatic round ligament.
