CONCLUSIONS: More than half of patients with ascending retrocecal appendicitis presented with atypical clinical presentation. [ncbi.nlm.nih.gov]

Here we present a patient of acute subhepatic-retrocaecal appendicitis in whom clinical and US findings mimicked acute cholecystitis. [tjtes.org]

• Abdominal Pain

  RESULTS: Patients presented with right lower abdominal pain (49%, 16/33), right flank pain (24%, 8/33), right upper abdominal pain (18%, 6/33), and periumbilical pain (15%, 5/33). [ncbi.nlm.nih.gov]

  In patients presented with right abdominal pain with atypical clinical, laboratory and ultrasound (US) findings, acute appendicitis should be eliminated with computed tomography (CT). [tjtes.org]

• Acute Abdomen

  Contrast-enhanced CT has reasonable accuracy in diagnosing appendicitis and can also reveal other causes of an acute abdomen. [msdmanuals.com]

• Obturator Sign

• Right Flank Pain

  A 3-year-old girl presented with high fever and right flank pain for more than 1 week. Ultrasonography showed a right perinephric fluid collection with normal renal parenchyma and collecting system. [ncbi.nlm.nih.gov]

  Two years later, she presented with fever, limping gait, and right flank pain. Ultrasound revealed fixed dilated bowel loops, a fecalith and a heterogeneous hypoechoic lesion (3.7×3.6×3.3 cm) at right psoas muscle, suspecting PA. [omicsonline.com]

• Right Lower Quadrant Tenderness

  Appendicitis in a patient with a retrocecal appendix may present atypically, with less or poorly localized pain, discomfort on coughing or walking, or flank, rather than right lower quadrant, tenderness. [acuteabd.weebly.com]

  Rovsing sign is positive when pain is felt with pressure at a point on the left side of the abdomen corresponding to McBurney point on the right. Rectal examination will detect tenderness in the right lower quadrant in more than half of patients. [clinicaladvisor.com]

  The most important physical examination finding is right lower quadrant tenderness to palpation. [aafp.org]

  Due to the location of the retrocecal appendix, right lower quadrant tenderness may not be observed. Therefore, there could be difficulties in the diagnosis (4). [turkjsurg.com]

• Pelvic Pain

  Atypical pain may present in various ways. Pelvic appendix – pain initially felt in RLQ, no visceral symptoms and pain on urination, may cause suprapubic pain (5). May present with profuse diarrhoea and pelvic pain. [teachmepaediatrics.com]

  The pain is not as severe as that associated with abdominal or pelvic appendicitis and the pain rarely localises well to the right iliac fossa. [surgwiki.com]

  Because many gynecologic conditions can mimic appendicitis, a pelvic examination should be performed on all women with abdominal pain. [aafp.org]

Most often, however a workup including lab tests and imaging is required. Workup Laboratory studies There is no single lab test specific for the diagnosis of appendicitis. [cdemcurriculum.com]

Before his extensive GI tract workup, he had undergone investigations to exclude cardiac, renal and liver disease. In addition, mucosal disease of the GI tract had been excluded. [ncbi.nlm.nih.gov]
