Summary
Orbital hydatid cysts, caused by Echinococcus granulosus, are rare but can lead to painless proptosis. Surgical removal via craniotomy and orbitotomy is effective for these zoonotic infections.
Area of Science:
- Parasitology
- Ophthalmology
- Neurosurgery
Background:
- Echinococcosis, a zoonotic disease caused by Echinococcus granulosus, affects humans as intermediate hosts.
- Orbital hydatid cysts represent a small but significant portion (1-2%) of all hydatid disease cases.
Observation:
- A case study of a 10-year-old boy presenting with unilateral painless proptosis.
- The patient was diagnosed with an orbital hydatid cyst.
Findings:
- Complete surgical excision of the orbital hydatid cyst was achieved through a combined frontal craniotomy and orbitotomy approach.
- The surgical procedure successfully removed the cyst without complications.
Implications:
- Unilateral painless proptosis in endemic regions warrants consideration of orbital hydatid cyst as a differential diagnosis.
- Early diagnosis and surgical intervention are crucial for managing orbital hydatid disease and preventing vision loss.

Ovarian Cycle
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
Ovaries
The ovaries are roughly the size of almonds and measure approximately 2 to 3 centimeters in length. These paired structures are situated within the pelvic region and are anchored by the mesovarium—a peritoneal extension that also connects them to the wider structure of the broad ligament. The support system extends to the suspensory ligament, housing blood and lymphatic vessels. In addition, the ovarian ligament tethers the ovaries to the uterus.

Atomic Orbitals
An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.
Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
