Introduction: In this paper, we report our experience with a case of primary hydatid cyst involving only the spleen in a 27-year-old sportsman treated by PAIR technique. Case Report: Five years before, a 27-year-old handball player being admitted to our hospital, it was detected the cyst in his spleen which size was 35 x 30 mm in diameter, by abdominal ultrasound during a systematic examination. There was no pain or any other symptoms at that time. Tests on the presence of echinococcus cysts were negative. After a period of 5 years, and regular check-ups, the patient began to feel a dull pain in the left upper quadrant area. The Echinococcus test was again negative. Puncture and aspiration of content was performed and sent to cytological analysis that confirmed the presence of Echinococcus. The CT finding showed the spleen in a normal position, shape, enlarged, 185 mm in longitudinal diameter (splenomegaly), with inhomogeneous parenchyma on the expense of rounded area with hyperdense halo, which did not opacify after contrast, located in the dorsal area of the spleen, 100x98 mm in diameter and which corresponded to the echinococcal cyst in differential diagnosis–clean dense contents (protein / haemorrhagic). Conclusion: The reported case is very specific, considering that handball is contact sport, where it is almost impossible to avoid the physical contact between players, which is sometimes even rough. Due to rough contacts, spleen trauma is something we should be very aware about, especially in cases of splenomegaly with hydatid cyst, where the spleen rupture might lead to fatal outcome. According to all this, careful follow up of this patient is necessary.

The optimal treatment for appendiceal mass formed after appendiceal rupture due to acute appendicitis is surrounded with controversy. The treatment strategy ranges from open surgery (emergency or interval appendectomy), laparoscopic appendectomy, and image-guided drainage, to conservative treatment with or without antibiotics. Nonsurgical treatment (including conservative and drainage treatment), followed by interval appendectomy to prevent recurrence, is the traditional management of these patients. The need for interval appendectomy after a successful conservative or/and image-guided drainage treatment, has recently been questioned as the risk of recurrence is relatively small. Several authors consider that even in cases involving only ambulatory follow-up observation, without interval surgery after conservative management, the recurrence rate and risks of missing underlying pathologies were not high. This article evaluates the minimally invasive treatment modalities in the management of appendiceal mass, risk of undetected serious disease, and the need for interval appendectomy to prevent recurrence.
