ABSTRACT

Adnexal torsion is a common gynecological emergency and a significant cause of acute pelvic pain in women. Hydrosalpinx-induced torsion of the adnexa is a rare situation and requires prompt and accurate management. Twenty-three years old nulliparous woman admitted in our structure for acute pelvic pain. The ultrasound revealed an enlarged right ovary with an adnexal cystic mass. We suspected the diagnosis of a right adnexal torsion due to cystic ovarian mass. Laparotomy revealed torsion of the right adnexa and a second large mass appearing to be a hydrosalpinx. Diagnosis of adnexal torsion is difficult and is based on a range of arguments obtained by anamnesis, clinical examination, ultrasonography and other investigations. Early diagnosis is important for preserving tubal and ovarian function, given the risk of ovarian necrosis in young women. Laparoscopy is the gold standard for diagnosing and treating adnexal torsion. The treatment can be conservative or radical, consisting of detorsion of the twisted adnexa, with or without adnexectomy.

ABSTRACT

Although it was first described over 100 years ago, lumbar puncture is still an important diagnostic tool for a variety of infectious and noninfectious neurologic conditions. With the widespread use of this common and relatively safe performed medical procedure, minor and major complications can occur even when standard infection control measures and good techniques are used, including post lumbar puncture headaches, infection, bleeding, cerebral herniation, radicular pain, and even pneumocephalus in extremely rare cases. We describe a previously unreported complication of lumbar puncture performed for the diagnosis of meningitis in a 33-year-old woman with no medical history causing pneumorrachis, tension pneumocephalus, and sacral meningocele infection leading to death. Lumbar puncture is a simple diagnostic procedure with few complications, but if the technique is incorrectly performed, or if it is accompanied by occult congenital malformations such as sacral anterior meningocele in our case, the consequences can be fatal.

ABSTRACT

Xanthogranulomatous pyelonephritis is a rare and aggressive form of chronic pyelonephritis, it can occur at all age groups but is more common in women than in men, supposedly relating to the increased incidence of urinary tract infections and chronic nephrolithiasis in woman. Computed tomography (CT) findings are very helpful in making the correct diagnosis, but the definitive diagnosis is still based on histology, as there are many differential diagnoses such as renal cell carcinoma and renal tuberculosis. The complications of this type of pyelonephritis are due to the involvement of adjacent organs. The most frequent ones are Psoas abscess, perinephric abscess, and sepsis. Nephrocutaneous and renocolic fistulas are less common. We report a case of a 61-year-old male, who presented to emergency for left-sided lumbar pain for whom radiological investigations confirmed a renocolic fistula complicating xanthogranulomatous pyelonephritis. The diagnosis of XGP was proven by histopathological examination of the nephrectomy specimen slides, but there was also association with an underlying malignant squamous differentiation consistent with urothelial carcinoma, which was not evident on CT. XGP is a rare variant of chronic pyelonephritis with known imaging features. The treatment of choice is nephrectomy and histopathological examination is required for final diagnosis, as there may be associated renal malignancy.

ABSTRACT

Close follow-up of patients with liver cirrhosis has led to increased detection of hepatocellular carcinoma (HCC) at an early stage, especially with magnetic resonance imaging (MRI) innovations. We report the case of a 70-year-old man, with a recent history of liver cirrhosis due to chronic hepatitis C virus (HCV) complicated by hepatocellular carcinoma (HCC), and for whom trans-arterial chemoembolization (TACE) was planned, as the patient was assigned Child B7 at admission. Angiography performed during the first TACE cycle shows not only the "tumor blush" corresponding to previously detected HCC but also an additional small foci of HCC uptake seen within a large dysplastic nodule giving the appearance of "nodule-within-nodule." Early detection of hepatocellular carcinoma improves prognosis. Hence, it is essential to be aware of all early aspects of HCC, including the nodule-within-nodule appearance on cross-sectional imaging, and also in angiography, as in this case.

ABSTRACT

Background: Intestinal carcinoid tumors are well-differentiated neuroendocrine tumors that are capable of secreting bioactive hormones and/or amines; These tumors are uncommon but are the most common primary tumors of the small intestine. Case presentation: We report the case of an 80-year-old woman who presented with a long history (about 14 years ago) of atypical digestive symptoms such as vague abdominal pain, alternating diarrhea, and constipation, treated as functional colopathy without improvement, until the day when she presented with worsening pain that prompted her consultation. CT scan revealed typical manifestations of a carcinoid tumor associated with signs of subacute small bowel ischemia. Despite the surgery being considered a gold standard treatment, it was rejected due to the extent of tumor mesenteric involvement, therefore, the patient received only somatostatin treatment. Conclusion: Small bowel carcinoid tumors are rare, with typical imaging features based on cross-sectional imaging (CE CT/MRI). Intestinal ischemia is a well-known complication that can be a factor in mortality.

ABSTRACT

Intestinal malrotation is a congenital rotational anomaly that results of abnormal rotation of the gut, said to occur in 1 in 6000 live births. Common mesentery predisposes to volvulus of the midgut and internal hernias due to the left position of the cecum and appendix. The association of this anomaly with acute left appendicitis is rarely reported in the literature. Occurrence of acute appendicitis on common mesentery is a source of diagnosis difficulties, which may lead to a surgical management delay. We report a case of a 10-year-old boy, admitted for a left-sided iliac pain whose radiological investigations confirmed a left acute appendicitis associated with complete common mesentery. The child underwent laparoscopic surgery with simple post-operative follow-up.

ABSTRACT

Background: Giant cell tumors (GCTs) are locally aggressive but rarely malignant bone neoplasms that uncommonly involve the skull. In this report, we describe a tumor of the sphenoid sinus. Case presentation: A 51-year-old female was presented with headache, and bilateral decreased visual acuity, CT scan, and brain MRI revealed an infra-sellar enhancing tumor expanding to the sellar and supra-sellar region which proved to be a GCT. the patient had received 03 months of preoperative denosumab-based treatment and imaging follow-up showed regression in size and morphology modifications of tumor tissue. Conclusion: This is one of few reports to describe the appearance of sphenoid bone GCT, and the first report to highlight the effects of short-term denosumab treatment in GCTb in such a location.

ABSTRACT

Acute intestinal intussusception in adults is a rare condition, most often secondary to an organic lesion (tumor or inflammation), representing 1%-5% of intestinal obstructions. Pure colic intussusception on lipoma rectal causing bowel obstruction is an exceptional situation. A 60-year-old man presented to the emergency department for acute abdominal pain with marked abdominal distention and red rectal bleeding. A contrast-enhanced abdominal CT scan was performed, which revealed a recto-sigmoid intussusception on lipoma, causing mechanical intestinal obstruction. The patient underwent a partial reduction of the intussusception with partial sigmoid resection and end colostomy. Colonic lipomas of the recto-sigmoid region represent a very rare condition and a subsequent etiology for intussusception and bowel obstruction in adults. However, it should be considered in the differential diagnosis of such situations.

ABSTRACT

Background: Carotid Web and focal carotid diaphragm are atypical fibromuscular dysplasia. The bilateral stroke due to this dysplasia is extremely rare. We will report a series of three young patients, admitted for a bilateral ischemic stroke caused by carotid bulb web and internal carotid diaphragm. Also, we will discuss their manifestations and treatment modalities. Case presentations: In our study, we will report a series of three North African patients, two females an one male, at the mean age of 37, admitted for an ischemic stroke caused by bilateral carotid bulb web and bilateral internal carotid diaphragm.All of our patients were young and didn't have a history of drug use. Conclusions: In our series, only end-vascular treatment was performed which was necessary to prevent any recurrence. Antiplatelet therapy was used in all cases to prevent any stroke during the follow-up.
