Hydatid Disease With Psoas and Gluteal Muscle Involvement Causing Cauda Equina Compression: A Case Report.

Hydatid disease is a zoonotic infection caused by the tapeworm, primarily affecting the liver and lungs, and rarely involving muscle tissue. Humans are infected by ingesting eggs from contaminated food or water. Patients may present with painless, slow-growing masses, sometimes associated with nerve or vessel compression, especially in cases of muscle involvement.

Peritoneal tuberculosis: a benign differential diagnosis of ovarian cancer with peritoneal carcinomatosis (a case report).

Peritoneal tuberculosis is a rare form of tuberculosis which gives a non-specific clinical picture which can be confused with several digestive pathologies. It can also mimic ovarian cancer at the stage of peritoneal carcinomatosis, hence the interest sometimes of a diagnostic laparoscopy which makes it possible to make the diagnosis which is confirmed by an anatomo-pathological study. This is the case of our patient who was initially diagnosed with ovarian cancer and the diagnosis was corrected in peritoneal tuberculosis after a laparoscopy.

Stromal tumor of the lesser omentum : a case report.

Gastrointestinal stromal tumors (GISTs) represent the majority of primary non-epithelial neoplasms of the digestive tract, most frequently expressing the KIT protein detected by immunohistochemical staining for the CD117 antigen. Extragastrointestinal stromal tumors (EGISTs), neoplasms with immunohistological features overlapping those of GISTs, are found in the abdomen outside of the gastrointestinal tract with no connection to the gastric or intestinal wall. We report the clinical, macroscopic and immunohistological features of an EGIST arising in the lesser omentum of a 58-year-old woman.

Left paraduodenal hernia: A rare cause of acute abdomen.

Paraduodenal hernia is a rare congenital anomaly that arises from an error of rotation of the midgut. The duodenum and the small intestine become trapped in a sac which is lined by the peritoneum, behind the mesentery of the colon, either to the right or left of the midline. It is therfore a rare and potentially life-threatening condition that can cause intestinal obstruction progressing to strangulation and perforation.
