Colo-colonic intussusception secondary to giant colonic lipoma in an adult: A case report.

INTRODUCTION: Intestinal intussusception is a rare complication in adults, accounting for 1 % of intestinal obstructions. Unlike in children, it is often secondary to a malignant lesion, rarely a benign one. Colonic lipomas are asymptomatic benign tumors often discovered incidentally. Colo-colonic intussusception due to a lipoma is exceptional. Here, we report a rare case of colo-colonic intussusception secondary to a giant caecal lipoma occurring in a 65-year-old woman. CASE PRESENTATION: A 65-year-old woman, was admitted in our surgical department for intermittent crampy abdominal pain in the right iliac fossa with an alternation of diarrhea and constipation over the past 10 months. The radiological investigation revealed a colo-colonic intussusception, most likely secondary to a fatty mass in the cecum. A right hemicolectomy was performed with ileocolic anastomosis because of the risk of malignancy. Histopathological examination confirmed the lipomatous nature of the lesion. The patient remained asymptomatic three years after surgery. CLINICAL DISCUSSION: Colonic lipomas are often asymptomatic. They can cause intussusception with clinical symptoms varying based on their size and location. CT scan has increased the number of preoperative diagnoses. Treatment options include surveillance, endoscopic intervention, or surgical resection. The appropriate surgical intervention remains a major challenge for surgeons due to the risk of malignancy. CONCLUSION: A giant colonic lipoma remains a very rare cause of colonic intussusception, especially in adults. CT scan plays a crucial role in diagnosis. Surgical resection remains the treatment of choice due to the risk of malignancy.

Xanthogranulomatous cholecystitis: Diagnostic dilemma and surgical solution in geriatric patients: A case report.

INTRODUCTION: Xanthogranulomatous Cholecystitis (XGC) is a rare inflammatory condition characterized by the presence of xanthogranulomas within the gallbladder wall, often mimicking gallbladder carcinoma (GBC). Diagnosis is challenging and may require biopsy. Once GBC is excluded, an open cholecystectomy is recommended, although laparoscopic cholecystectomy is increasingly being performed with great caution. This case report aims to evaluate clinical and radiological features, surgical outcomes, and treatment approaches for XGC. CASE PRESENTATION: A 70-year-old patient presented with right hypochondrial pain and a palpable gallbladder. A CT scan revealed a distended lithiasic gallbladder with a thickened irregular wall and hepatic nodules. A hepatic MRI suggested xanthogranulomatous cholecystitis. A CT-guided biopsy of the liver nodule showed no signs of malignancy. An open cholecystectomy with a trans-cystic drain was performed. Histological examination confirmed chronic xanthogranulomatous cholecystitis. The patient was discharged on postoperative day 10. A clinical and radiological follow-up at 6 months postoperatively showed no abnormalities. CLINICAL DISCUSSION: XGC presents diagnostic challenges due to its resemblance to GBC. Imaging aids in diagnosis, but biopsy may be necessary. Open cholecystectomy is the recommended surgical treatment due to excessive local inflammation and the risk of concomitant malignancy. CONCLUSION: Managing XGC demands a holistic approach that integrates all clinical insights and mandates close collaboration among a multidisciplinary team of surgeons, radiologists, and pathologists. Further research is needed to refine diagnostic and therapeutic strategies for this rare condition, especially in geriatric patients.

Doubly complicated: A case of massive non-parasitic liver cyst presenting with dyspnea and inferior vena cava compression: A rare case report.

INTRODUCTION AND IMPORTANCE: Simple hepatic cysts, common benign liver conditions, are increasingly detected incidentally due to advancements in imaging technologies. While typically asymptomatic, complications such as compression of neighboring structures can arise, presenting unique diagnostic and management challenges. We present a doubly complicated case of a massive non-parasitic liver cyst in a 61-year-old female patient, manifesting with dyspnea and compression of the inferior vena cava. CASE PRESENTATION: A 61-year-old female with a history of treated hypertension presented with worsening dyspnea over six months. Physical examination revealed a large, painless abdominal mass, and imaging confirmed a 20 cm cystic liver mass compressing the inferior vena cava and exerting a mass effect on the diaphragm. Surgical exploration and deroofing of the cyst led to successful resolution. CLINICAL DISCUSSION: The presentation of dyspnea in non-parasitic liver cysts is rare but notable, highlighting the importance of considering hepatic etiologies in respiratory symptoms. Imaging modalities such as ultrasound and CT play crucial roles in diagnosis, while MRI aids in ruling out biliary-cystic fistulas. Surgical management, particularly subcostal laparotomy, remains a viable option for complex cases. CONCLUSION: This case underscores the need for heightened awareness of atypical presentations of non-parasitic liver cysts and the significance of imaging in diagnosis. Subcostal laparotomy, though associated with limitations, remains valuable in select cases. Further research comparing surgical approaches is warranted to optimize management strategies for symptomatic non-parasitic liver cysts.

A case report: Peritonitis secondary to perforated locally advanced gastrointestinal stromal tumor.

INTRODUCTION AND IMPORTANCE: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms predominantly affecting the gastrointestinal tract. While they often remain asymptomatic, GISTs can lead to acute abdominal emergencies, such as peritonitis secondary to tumor perforation, a rare yet serious complication. Here, we present a unique case of a locally advanced ileal gastrointestinal stromal tumor complicated by generalized purulent peritonitis, emphasizing the diagnostic and management challenges associated with this condition. CASE PRESENTATION: A 68-year-old male presented with worsening abdominal pain, vomiting, fever, and weight loss. Imaging studies revealed a large solid-cystic mass originating from the terminal ileum, prompting emergency surgery. Intraoperative findings included a multilobulated tumor mass invading the mesocolon, necessitating hemicolectomy. Histopathological analysis confirmed a high-risk gastrointestinal stromal tumor, leading to initiation of adjuvant therapy with imatinib mesylate. CLINICAL DISCUSSION: GISTs often present with nonspecific symptoms, posing diagnostic challenges. Peritonitis secondary to tumor perforation is a rare yet critical complication requiring prompt surgical intervention. Complete resection remains the mainstay of treatment, with adjuvant imatinib therapy showing promise in high-risk cases. CONCLUSION: This case report sheds light on the complexities of diagnosing and managing locally advanced gastrointestinal stromal tumors (GISTs) complicated by peritonitis. Complete tumor resection is crucial for potential cure, with adjuvant therapy using imatinib showing promise, especially in high-risk cases. Thorough diagnostic assessment, timely intervention, and comprehensive follow-up are essential for optimizing outcomes in complex GIST presentations.
