There are many kinds of unusual presentations or associations and clinical mimics of acute appendicitis, and definitive diagnosis requires knowledge of the imaging findings in some cases. The unusual presentations and associations of acute appendicitis included in this study are perforated appendicitis, acute appendicitis occurring in hernias, acute appendicitis with cystic endosalpingiosis, intussusception of appendix, and acute appendicitis with pregnancy. We also present uncommon gastrointestinal, urinary and gynecologic clinical mimics of acute appendicitis including anomalous congenital band, duplication cysts, giant Meckel' s diverticulitis, inflammatory fibroid polyp, renal artery thrombosis, spontaneous urinary extravasation and OHVIRA syndrome. Familiarity with these entities may improve diagnostic accuracy and enable the quickest and most appropriate clinical management.

The data suggest that the prevalence of HBsAg positivity is gradually decreasing among pregnant women, while the level of HBsAg antibody seropositivity is lower than expected. HBV carrier rate increases with increasing age and gravidity. In addition to the national HBV immunisation programme, the prevention of perinatal transmission should also be prioritised to decrease the HBV pool of infection.

Here we present the case of an adult male patient with the anomalies of polysplenia, Kartagener syndrome, dorsal pancreas agenesis, and adult polycystic kidney disease. Familiarity with this extremely rare coincidence may improve diagnostic accuracy and patient management.Keywords: Polysplenia, Kartagener syndrome, dorsal pancreas agenesis, polycystic kidney disease ÖZ Polispleni, Kartagener sendromu, dorsal pankreas agenezisi ve polikistik böbrek hastalığı olan erişkin bir erkek hasta sunuyoruz. Bu çok nadir birlikteliğin iyi bilinmesi tanısal doğruluğu ve hasta tedavisini artırabilir.

Lemierre’s syndrome is an illness characterized by internal jugular vein thrombophlebitis related to infectious agents, primarily Fusobacterium necrophorum. These bacteria, residing in both the oropharynx and the gastrointestinal tract, may lead to pylephlebitis, a serious condition that could result in the development of hepatic abscesses. This manifestation of the disease is regarded as the abdominal variant of Lemierre’s syndrome. Patients with gastrointestinal malignancies, especially those who undergo surgeries, are susceptible to the abdominal variant of Lemierre’s syndrome. Timely diagnosis is required to avoid the life-threatening complications of the abdominal variant of Lemierre’s syndrome. Diffusion-weighted magnetic resonance imaging (MRI) might be very useful in differentiating this disease from liver metastasis in patients with malignancies. Radiologists and clinicians need to be aware of this challenging condition to prevent misdiagnosis, since prompt treatment is often lifesaving.

Centor score of 3 or more together with high CRP, neutrophilia, and lymphocytopenia is predictive for GABHS tonsillopharyngitis.
