Systemic lupus erythematosus (SLE) is a complex autoimmune disease where the body loses tolerance to its own antigens, particularly nuclear antigens. Abnormal responses from T and B cells lead to the production of autoantibodies and the formation of immune complexes in tissues, triggering complement activation, inflammation, and irreversible organ damage. SLE can affect any part of the body, resulting in diverse clinical symptoms. One rare manifestation of SLE is lupus mesenteric vasculitis (LMV), which presents with vague symptoms, abnormal laboratory findings, and specific imaging features. LMV, although uncommon, can progress to severe complications such as bowel perforation, haemorrhage, and even mortality. Here, we report a case of LMV with the involvement of multiple organ systems (including mucocutaneous, musculoskeletal, serosal cavities, and haematological systems), presenting initially with life-threatening intractable gastrointestinal bleeding, and complicated by severe pulmonary infection. By sharing this case, we aim to enhance clinicians' confidence in managing critical SLE cases and raise awareness about disease surveillance.

INTRODUCTION AND IMPORTANCE
Gallbladder volvulus is a rare surgical disease with clinical manifestations similar to acute acalculous cholecystitis. Diagnosing gallbladder volvulus is critical as delayed surgical intervention in gallbladder volvulus is associated with high morbidity and mortality.
CASE PRESENTATION
A 62-year-old male patient presented to our outpatient department for right upper quadrant pain of one-month duration. Taking into consideration the patient's clinical symptoms, laboratory results, and imaging findings, we diagnosed the patient with acute acalculous cholecystitis and started intravenous antibiotics. After 3 days, the clinical progress was unfavorable, laparoscopic cholecystectomy was performed, and the final diagnosis of gallbladder was done intraoperatively. The postoperative course was uneventful, and the patient was discharged on the second day after surgery.
CLINICAL DISCUSSION
The cause of gallbladder volvulus may be related to abnormal embryological development, resulting in a long mesentery gallbladder and consequently leading to a floating gallbladder. Patients with gallbladder volvulus often do not exhibit specific signs, and the symptoms typically resemble those of acute acalculous cholecystitis. Once gallbladder volvulus is diagnosed, the surgical intervention must be conducted immediately.
CONCLUSION
Gallbladder volvulus is a relatively rare and challenging condition to diagnose. It should be considered in cases of acute acalculous cholecystitis, especially in elderly, thin patients who do not respond to antibiotic treatment. Cholecystectomy is the definitive treatment for gallbladder volvulus. In particular, laparoscopic surgery should be chosen initially.

BACKGROUND
Although relatively uncommon, lymphoma is the most prevalent haematopoietic neoplasia in horses, and multicentric lymphoma remains the most common presentation of the disease. The pathogenesis of equine lymphoma is still poorly understood and the diagnosis is usually confirmed at an advanced stage of the disease, compromising the prognosis. This study investigated the clinical, pathological, and molecular features of a case of equine multicentric lymphoma.
CASE DESCRIPTION
An apparently healthy 5-year-old crossbreed mare hospitalized at the Centre of Animal Reproduction of Vairão, Portugal, suddenly presented clinical signs of supraorbital oedema and mandibular lymph node enlargement, developing fever, facial oedema, and generalized lymphadenopathy. The mare ended up dying twenty-four days after the first clinical signs due to multisystem organ failure. Haematological and biochemical analyses, necropsy, and microscopic and molecular evaluation of affected tissues were performed. At necropsy, the main findings were multiple multinodular lesions, distributed along the serous surface of oropharynx, trachea, pericardium, gastrointestinal tract, and mesentery. Microscopically, these consisted of solid proliferations of neoplastic round cells that exhibited immunopositivity for CD3 (T cells). Based on these findings, a medium-grade multicentric T-cell lymphoma was diagnosed.
CONCLUSION
There is still very little research regarding the molecular characterization of lymphoma in horses. As an entity itself is quite heterogeneous, it is important to describe the interspecies particularities to understand its development and behaviour.

Review
BACKGROUND
Pseudomyxoma peritonei is an infrequent condition with a global annual incidence of only one to two cases per million people. Mucinous neoplasms, widespread intraperitoneal implants, and mucinous ascites characterize it. Currently, most clinicians misdiagnose this condition, which leads to delayed management.
CASE PRESENTATION
A 44-year-old North Indian female presented with a 1.5-month history of an abdominal lump. Physical examination revealed a sizeable abdominopelvic mass at 36 weeks. Contrast-enhanced computed tomography showed a massive multiloculated right ovarian cystic mass measuring 28 × 23 × 13 cm with mild ascites and elevated carcinoembryonic antigen levels (113.75 ng/ml). A provisional diagnosis of ovarian mucinous neoplasm was made, for which the patient underwent laparotomy. Intraoperatively, there were gross mucinous ascites, along with a large, circumscribed, ruptured right ovarian tumor filled with gelatinous material. The appendicular lump was also filled with mucinous material along with the omentum, ascending colon, right lateral aspect of the rectum, splenic surface, and small bowel mesentery. Cytoreductive surgery was performed along with an oncosurgeon, including total abdominal hysterectomy with bilateral salpingoophorectomy, omentectomy, right hemicolectomy, lower anterior resection, ileo-transverse stapled anastomosis with proximal ileal loop diversion stoma, excision of multiple peritoneal gelatinous implants, and peritoneal lavage. Histopathology and immunohistochemistry confirmed the presence of intestinal-type mucinous carcinoma. Postoperatively, the patient was given six cycles of chemotherapy. She tolerated it without any specific morbidity and had an uneventful recovery. Postoperative follow-up at 15 months revealed normal tumor marker levels and abdominal computed tomography findings and no signs suggestive of local recurrence or distal metastases.
CONCLUSIONS
Pseudomyxoma peritonei is a rare disease that is frequently misdiagnosed in the preoperative phase. Therefore, radiologists and clinicians should maintain a high index of suspicion for accurate diagnosis and multidisciplinary management.

BACKGROUND
Sigmoid volvulus (SV) is an acute abdominal condition characterized by torsion of the sigmoid colon around the mesentery, and often results in intestinal obstruction that may progress to bowel ischemia, necrosis, or perforation. Although SV commonly occurs due to predisposing factors like anatomic variations, age-related motility disorders, chronic constipation, and neurologic diseases, its incidence following sigmoid colon cancer surgery has rarely been reported. Herein, we report a rare case of recurrent SV following laparoscopic sigmoidectomy, which was successfully treated by laparoscopic redo surgery.
CASE PRESENTATION
The patient was a 77-year-old man who had previously undergone laparoscopic sigmoidectomy for sigmoid colon cancer. Sixteen months postoperatively, he developed an incisional hernia at the umbilical site, which was treated with a laparoscopic repair using an intraperitoneal onlay mesh. After the hernia surgery, the patient had no anastomotic leakage or stenosis on regular follow-ups. However, 65 months after the first surgery, he presented with abdominal pain and distension. A computed tomography revealed that the remnant sigmoid colon was distended in a twisting manner around the anastomosis, leading to the diagnosis of SV. Although endoscopic de-torsion was successful, the SV recurred 2 months later, requiring elective laparoscopic redo surgery. The procedure involved resection of the sigmoid colon including the prior anastomosis with a left pararectal incision and DST re-anastomosis using a 25-mm circular stapler. The operation lasted 165 min with minimal bleeding and no complications. The postoperative course was uneventful. Pathological analysis confirmed fibrosis without malignancy. The patient remains well without recurrence of SV and anastomotic stenosis more than 5 years after surgery.
CONCLUSION
SV following sigmoid colon cancer surgery has rarely been reported. This case illustrates the potential need for prophylaxis against postoperative SV, especially in patients with long sigmoid colon undergoing laparoscopic surgery for colorectal cancer. Further, laparoscopic redo surgery following initial laparoscopic surgery for colorectal cancer can be performed with minimal invasiveness, especially if patient selection is properly managed.

INTRODUCTION
Cystic echinococcosis, a zoonotic disease caused by the larval form of , predominantly affects the liver and lungs, with humans acting as accidental hosts.
METHODS
Our retrospective study at the Department of Radiology and Imageology, Nizam's Institute of Medical Sciences, included 187 histopathologically or serologically proven cases. The mean age of presentation was 49.4 years.
RESULTS
Liver involvement was most prevalent, accounting for 83.4% (n=156) of cases, followed by sporadic involvement of other organs such as the mesentery, spleen, pancreas, thalamus, kidney, lung, spine, and omentum. Characteristic diagnostic features observed on imaging included peripheral calcifications in 33% of cases, internal septations in 25% (n=47), dense calcifications in 15% (n=29), daughter cysts in 6% (n=11), and floating membranes in 5% (n=10). Among hepatic lesions, 90% (n=141) were showing involvement of a single lobe. Notably, 78% (n=110) of lesions were limited to the right lobe, 21% (n=30) to the left lobe, and 1% (n=1) to the caudate lobe. The most affected hepatic segment was segment VIII, while the least common was segment I (caudate lobe). Complications were identified in 13% (n=25) of cases of hepatic hydatidosis.
CONCLUSIONS
The findings of our study emphasize the systemic nature of infection which can affect various organs in the body. It also illustrates the invaluable insights imaging provides for timely and accurate diagnosis of hydatid disease.

We report a very rare case of delayed necrosis of the reconstructed colon 6 months after esophagectomy.A 67-year-old male patient had undergone esophagectomy with gastric tube reconstruction for esophageal cancer in 2014. Subsequently, total gastrectomy and ileo-colon reconstruction via a retrosternal route was performed for gastric tube cancer in 2022. Six months later, he suffered acute chest pain and came to our hospital. Contrast-enhanced CT showed severe dilation of the reconstructed colon with poor enhancement of the wall opposite mesentery, without arterial obstruction. Endoscopy showed no ischemic changes in the esophago-ileum anastomosis; however, mucosal color change to black was observed in the reconstructed colon. We diagnosed ischemic colitis of the reconstructed colon and started conservative treatment; however, 18 days later, he developed a right pyothorax due to perforation of the reconstructed colon. We performed necrosed colectomy with right chest drainage and cervical esophageal fistula was made. Histopathological examination revealed mucosal detachment, thinning of the muscularis propria, and ghost-like appearance of crypt. If necrosis of the reconstructed colon is suspected in the late postoperative period, endoscopic findings of the colonic mucosa may be useful in determining surgical treatment, even in the absence of arterial blood flow obstruction.

Review
Internal hernias are herniations of abdominal viscera, usually small bowel, through congenital or acquired openings of the peritoneum or mesentery. Congenital hernias may involve anatomic fossae such as the epiploic foramen as well as those related to abnormal peritoneal or mesenteric defects; these include left and right paraduodenal, transomental, transmesenteric, pericecal and broad ligament hernias. Acquired hernias are due to defects in the mesentery or peritoneum, usually resulting from prior surgeries, and include those associated with Roux-en-Y surgery as well as colorectal cancer resections. Internal hernias account for 5.8% of small obstructions. Obstructed internal hernias are considered surgical emergencies due to the high risk of bowel strangulation. This review summarizes the various types of congenital and acquired internal hernias, their relevant anatomy, embryology, associated surgical history and imaging appearance. We will also discuss a location-based approach to identifying internal hernias on CT, as well as complications and relevant signs, of which abdominal imagers should be vigilant.

Intra-abdominal desmoid tumors are a rare and complex clinical problem. These tumors are locally invasive, and surgical ablation represents the mainstay of treatment. When localized at the root of the mesentery, their resection may require extensive excision of the intestine resulting in intestinal failure and life-long total parenteral nutrition. Intestinal transplantation, either autotransplantation or allotransplantation, has been used as a viable option to treat this group of patients. Herein, we describe a series of 4 patients with unresectable intra-abdominal desmoid tumor who underwent cadaveric isolated intestinal and ascending colon transplantation.
